Fisch) and white pigweed (Chenopodium album L.) on wheat (Triticum aestivum L.) plants cv. Lenigradskaya 6, growing under hydroponic conditions and osmotic stress (generated by 12% polyethylene glycol-6000 (PEG)). Based on the assumption that plants create a unique microbiome that helps them overcome various stresses, we hypothesized that bacteria isolated from drought-tolerant plants may assist cultivated wheat plants in coping with drought stress. PGPB were isolated from seeds and leaves of plants and identified as Bacillus spp. (strains Cap 07D, Cap 09D, and App 11D); Paenibacillus sp. (Cap 286); and Arthrobacter sp. (Cap 03D). All bacteria produced different phytohormones such as indole acetic acid (IAA), abscisic acid (ABA), and gibberellic acid (GAS3) and were capable of stimulating wheat growth under normal and osmotic stress conditions. All PGPB reduced the malondialdehyde (MDA) content, increased the total chlorophyll content by increasing chlorophyll a, and modulated wheat hormone homeostasis and CAT and POX activities under osmotic conditions. Selected strains can be promising candidates for the mitigating of the drought stress of wheat plants.

The effects of spraying salicylic acid (SA) during the grain-filling stage on the salt tolerance of progeny seeds in wheat (Triticum aestivum L.) were investigated in this study. The results showed that spraying SA during the grain-filling stage significantly increased the grain weight and yield of wheat plants. Meanwhile, the seeds from the SA-treated plants showed a higher germination rate, length and dry mass of the coleoptile and radicle, and a lower mean germination time compared to the seeds of water-treated plants under the salt germination condition, indicating that SA pretreatment during the grain-filling stage could effectively improve the salt tolerance of progeny seeds in wheat. SA pretreatment significantly increased the activities of amylases and the respiration rate, accompanied by a decrease in starch content, and a higher accumulation in the level of soluble sugars and adenosine triphosphate (ATP) in the germinated seedlings compared to the water pretreatment under salt stress. In addition, SA pretreatment obviously alleviated the increase in malondialdehyde (MDA) content and the reactive oxygen species (ROS) release rate in seedlings by activating antioxidant enzymes (superoxide dismutase (SOD) and peroxidase (POD)) under salt stress. Moreover, the seedlings of the SA-treated plants showed lower Na + and higher K + contents compared to the seeds of water-treated plants under salt stress. The results of this study indicate that spraying SA during the grain-filling stage improves the capacity of offspring seeds to maintain osmotic and ion balance and redox homeostasis under salt stress, thereby conferring salt tolerance to the wheat seeds.

Maek. has been employed in traditional Chinese medicine for millennia. Nevertheless, the small size and the paucity of research on its pharmacological effects have restricted its extensive utilisation in clinical medicine. Polyploid breeding represents an effective method for the rapid enhancement of plant biomass and metabolites. In this study, the most effective in vitro method for inducing tetraploid formation was identified as axillary buds treated in a solution of colchicine at a concentration of 1% for 24 h. Meanwhile, a comparison between tetraploids and diploids yielded two significant findings: (1) The presence of 6-zonocolpate and 8-zonocolpate pollen grains can be used as distinguishing characteristics for diploid and tetraploid, respectively. (2) Genome duplication resulted in alterations to the polyphenol species and synthesis pathway in E. splendens. The accumulation of wogonin, oroxylin A, baicalin, chrysin, acacetin and related derivatives was markedly greater in tetraploid plants, whereas apigenin, naringenin, scutellarein and related derivatives were found to accumulate to a greater extent in diploid plants. It is noteworthy that wogonin and oroxylin A were uniquely detected in tetraploids, indicating that the generated tetraploids may harbor novel pharmacological value. The findings not only provided new insights into the metabolic mechanism of polyploidisation but also established a foundation for the selection and breeding of novel genetic resources of E. splendens.

Studying the effect of light and darkness on the germination of somatic embryos led to the development of a modified protocol for inducing date palm somatic embryo germination and conversion into plants. Two types of somatic embryos were obtained, individual somatic embryos with bipolar structures and cluster primary embryos that multiplied to the cluster somatic embryos. The cluster embryos produced cluster shoots up on germination, while individual embryos developed into a single plantlet. The cluster somatic embryos that germinated in the dark exhibited sustained and vigorous growth, leading to the formation of long etiolated stems with thin leaves. Germination under darkness significantly shortened the conversion period of cluster somatic embryos into plants from 20 weeks, when using light, to only 7 weeks for both germination and elongation in one stage. Moreover, the plants incubated in the dark had the greatest percentage of rooting and plant acclimatization. Taken together, these results led to the development of an efficient new and simple protocol for date palm micropropagation, which led to improved germination and growth and significantly reduced time and costs.

Young leaf explants were cultured on modified Murashige and Skoog (MS) medium containing different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D; auxin) (1, 2, and 4 mg L-1) and two Dicamba concentrations (4 and 6 mg L-1). The highest callus induction rate was achieved with 2 mg L-1 of 2,4-D. Subsequently, particle bombardment was used to introduce genetic constructs containing the uidA reporter gene driven by three promoters (CaMV35S, ubiquitin, and actin1) into the embryogenic calli. We assessed the impact of various biological, physical, and DNA parameters, including bombardment pressure, target distance, particle size, DNA amount, and osmotic pretreatment, through histochemical GUS assay to quantify blue spots. Results showed that the most effective combination involved bombardment at 1100 psi, 6 cm target distance, 1 μm gold particles coated with 1 μg DNA, under a vacuum of 25 inHg. Additionally, the best osmotic pretreatment utilized a solution containing 0.2 M sorbitol and 0.2 M mannitol. Notably, the construct driven by the ubiquitin promoter resulted in the highest transient expression of the uidA gene, suggesting its superiority for gene expression in this system.

Banana plants production can be increased through tissue culture with the use of explants and the right combination of hormones. This study was conducted to determine the use of flower apices explants on local banana varieties using a combination of cytokinin hormones containing BAP (Benzylaminopurine) and several levels of TDZ (Thidiazuron). The result of this research was analyzed using a one-way analysis of variance. The hormone combination in this study consists of MS + BAP 2 mg/L + three concentrations of TDZ (2 mg/L, 2.5 mg/L, and 3 mg/L) as a regeneration medium. Three local banana varieties (Kepok Putih, Kepok Kuning, and Pisang Susu) was cultured on the three combination medium. The results showed that the use of flower apices explants contained in banana flowers grown on MS media with a combination of cytokinin hormones could increase the efficiency of explant regeneration. Media MS + BAP 2 mg/L + TDZ 3 mg/L gave the best regeneration rate for Kepok Putih (62.50%), Kepok Kuning (62.50%) and Banana Susu (56.25%) compared to TDZ 2. mg/L and TDZ 3 mg/L. The novelty of this study can provide information in the propagation of local banana plants using flower apices explants

Kale plants are diploid (2n = 2x = 30) with small stem and leaf morphology. One of the efforts to increase productivity and biomass can be done by increasing ploidy. Induction using colchicine has been widely done in the process of polyploidization in plants and most of these inductions are successful. Colchicine with the right concentration will weaken the preparation of microtubules, this causes the mitotic stage to be inhibited resulting in the number of chromosomes in the plant will be doubled and produce polyploid plants. This type of research is experimental research in the form of polypoid induction in kale plants by administering colchicine. The treatment was given by soaking the kale seeds for 24 hours in colchicine solution consisting of control concentration (T0), 0.1% (T1), 0.3% (T2) and 0.5% (T3). In this study, no kale chromosomes were seen due to factors such as not using hydrolysis solution and lack of skill in squashing. In this study, kale chromosomes were not visible in all treatments. Many factors caused the invisibility of kale chromosomes such as not using hydrolysis solution and lack of skill in squashing. It is recommended that this research be developed again in the methods and solutions used so that chromosomes can be seen under the microscope

The ISSR marker demonstrated a higher degree of polymorphism (13.6%) compared with RAPD (3.5%). The polymorphic information content averaged 0.484 for ISSR and 0.354 for RAPD. The B. gymnorrhiza samples from Alappuzha and Thrissur clustered together in both markers. Nei's genetic diversity index (h) was determined to be 0.430 for RAPD and 0.453 for ISSR. The unweighted pair group with the arithmetic mean dendrogram, reflecting a greater degree of polymorphism, supports the conservation of B. gymnorrhiza throughout Kerala's west coast. Additionally, the marker index was calculated as 0.506 for ISSR and 0.392 for RAPD, highlighting the efficacy of ISSR markers in assessing the genetic diversity of B. gymnorrhiza.

It allows for the rapid identification of induced polyploids or mixoploids and plantlets with unchanged ploidy levels compared to the conventional method of chromosome counting. Therefore, the present study aims to optimize and develop an efficient FCM analysis
procedure to determine the ploidy level and DNA content of Neolamarckia cadamba. This involved investigating various types of leaf tissues of N. cadamba and lysis buffers to identify the best tissue-buffer combination for FCM analysis. The histograms generated by FCM analysis revealed that only fresh leaves combined with LB01 buffer produced clean histograms with sharper peaks, reduced noise, and low coefficient of variation values. FCM analysis effectively classified the nodal explants of N. cadamba treated with colchicine into three distinct groups of polyploid
plants: tetraploids, mixoploids, and octoploids. The N. cadamba tetraploids were found to have an estimated DNA content of 2.59 ± 0.09 pg, while octoploids showed an increase of DNA content to 5.35 ± 0.24 pg. These results highlight the effectiveness of FCM as a valuable tool in identifying mixoploids among the colchicine-induced polyploids of N. cadamba, as compared to the conventional method of chromosome counting. Mixoploids, which are characterized by cells with varying ploidy levels, deserve further investigation in future research.

These metabolic and health indices were examined in Clarias gariepinus fed with Zingiber officinale (ginger) roots-powder supplemented diets in 40-litre freshwater-filled plastic tanks. 120 C. gariepinus fingerlings (weight, 2.33±0.07g) were fed with 40% crude protein diets containing three concentrations of Zingiber officinale roots-powder: GRP1-1%; GRP2-2%; GRP3-3%, and control-0% ad libitum twice daily for 12 weeks. Significant differences (p < 0.05) occurred in the growth parameters except feed conversion ratio and specific growth rate. Survival rate decreased as concentration of powder increased. Differences (p<0.05) seen in packed cell volume (PCV), Haemoglobin (Hb), and Red blood cell (RBC), thus highest in GRP3: PCV (37.00±1.16%), Hb (12.37±0.37g/dl) and RBC (3.47±0.08 x 10 6 /l) and lowest in control: PCV (22.00±0.58%), Hb (7.37±0.20g/dl) and RBC (2.07±0.06 x 10 6 /l). Liver histology of control fish was normal, while fatty degenerations were seen in the treated fish. The histology of fish kidney was normal in all treatments. The study concluded that 1% ginger root-powder dietary supplementation in cultured C. gariepinus could effectively improve the metabolic activities, health profile and survival of the fish.

To ensure high quality and efficient field production, the industry relies on a uniformity of elite cocoa plants, which can be achieved through vegetative propagation methods like somatic embryogenesis. However, the low yield rate in the multiplication and regeneration of cocoa plants remains a challenge for basic research. To obtain a greater number of secondary somatic embryos (SSE) in cocoa, the effect of three osmoregulators on the disc cells of primary somatic embryos (PSE) of cocoa was studied. PSE was induced from cocoa staminodes of genotype I52. Epicotyls were selected from PSE at the torpedo and cotyledon stages, segmented into 3 mm discs, and placed in a secondary callus growth medium. The explants were transferred to embryo development medium 3, where they were exposed to the osmoregulatory polyethylene glycol (PEG), mannitol, and sorbitol at the following concentrations: 0%, 1%, 3%, and 5%. D-Mannitol at 3% and D-Sorbitol at 1% increased the number of SSE at the torpedo, globular, and cotyledon stage per explant. The culture medium with 1% PEG significantly increased the formation of SSE in the globular and cotyledonal stages. The results presented a positive effect of the osmoregulators on the formation of cocoa SSE.

Establishing a method for rapid and efficient regeneration of E. bungeanus is essential to achieve industrial-scale production. The aim of this study was to establish a rapid tissue propagation technique for E. bungeanus and provide a foundation for the industrial production of tissue-cultured seedlings. Using stem segments of E. bungeanus as explants, we investigated effects of explant collection time, sterilization method, various culture media, and ratios of plant growth regulators on the initiation, subculture, and rooting stages of the tissue culture process for E. bungeanus. The optimal explant collection time was mid-April; a combination of 75% ethanol for 20 s, followed by 0.1% HgCl2 for 7 min was suitable for disinfection, yielding a survival rate of 55.00% for the explants. Initiation culture using the woody plant medium (WPM) supplemented with 1.0 mg L-1 of 6-benzylaminopurine (6-BA) and 0.2 mg L-1 of α-naphthalene acetic acid (NAA) achieved an induction rate of 87.22% for explants. Proliferation culture on ¼ WPM medium containing 2.0 mg L-1 of 6-BA and 0.1 mg L-1 of NAA resulted in a propagation coefficient of 4.98. Rooting culture on ½ Murashige and Skoog (MS) medium supplemented with 0.2 mg L-1 of indole-3-butyric acid achieved a rooting rate of 78.33%. However, the rooting rate was low, indicating the need for further optimization of rooting and acclimatization. This study is the first to develop a rapid and efficient regeneration system for E. bungeanus using stem segments.

Banana plants production can be increased through tissue culture with the use of explants and the right combination of hormones. This study was conducted to determine the use of flower apices explants on local banana varieties using a combination of cytokinin hormones containing BAP (Benzylaminopurine) and several levels of TDZ (Thidiazuron). The result of this research was analyzed using a one-way analysis of variance. The hormone combination in this study consists of MS + BAP 2 mg/L + three concentrations of TDZ (2 mg/L, 2.5 mg/L, and 3 mg/L) as a regeneration medium. Three local banana varieties (Kepok Putih, Kepok Kuning, and Pisang Susu) was cultured on the three combination medium. The results showed that the use of flower apices explants contained in banana flowers grown on MS media with a combination of cytokinin hormones could increase the efficiency of explant regeneration. Media MS + BAP 2 mg/L + TDZ 3 mg/L gave the best regeneration rate for Kepok Putih (62.50%), Kepok Kuning (62.50%) and Banana Susu (56.25%) compared to TDZ 2. mg/L and TDZ 3 mg/L. The novelty of this study can provide information in the propagation of local banana plants using flower apices explants

Kale plants are diploid (2n = 2x = 30) with small stem and leaf morphology. One of the efforts to increase productivity and biomass can be done by increasing ploidy. Induction using colchicine has been widely done in the process of polyploidization in plants and most of these inductions are successful. Colchicine with the right concentration will weaken the preparation of microtubules, this causes the mitotic stage to be inhibited resulting in the number of chromosomes in the plant will be doubled and produce polyploid plants. This type of research is experimental research in the form of polypoid induction in kale plants by administering colchicine. The treatment was given by soaking the kale seeds for 24 hours in colchicine solution consisting of control concentration (T0), 0.1% (T1), 0.3% (T2) and 0.5% (T3). In this study, no kale chromosomes were seen due to factors such as not using hydrolysis solution and lack of skill in squashing. In this study, kale chromosomes were not visible in all treatments. Many factors caused the invisibility of kale chromosomes such as not using hydrolysis solution and lack of skill in squashing. It is recommended that this research be developed again in the methods and solutions used so that chromosomes can be seen under the microscope

The ISSR marker demonstrated a higher degree of polymorphism (13.6%) compared with RAPD (3.5%). The polymorphic information content averaged 0.484 for ISSR and 0.354 for RAPD. The B. gymnorrhiza samples from Alappuzha and Thrissur clustered together in both markers. Nei's genetic diversity index (h) was determined to be 0.430 for RAPD and 0.453 for ISSR. The unweighted pair group with the arithmetic mean dendrogram, reflecting a greater degree of polymorphism, supports the conservation of B. gymnorrhiza throughout Kerala's west coast. Additionally, the marker index was calculated as 0.506 for ISSR and 0.392 for RAPD, highlighting the efficacy of ISSR markers in assessing the genetic diversity of B. gymnorrhiza.

It allows for the rapid identification of induced polyploids or mixoploids and plantlets with unchanged ploidy levels compared to the conventional method of chromosome counting. Therefore, the present study aims to optimize and develop an efficient FCM analysis
procedure to determine the ploidy level and DNA content of Neolamarckia cadamba. This involved investigating various types of leaf tissues of N. cadamba and lysis buffers to identify the best tissue-buffer combination for FCM analysis. The histograms generated by FCM analysis revealed that only fresh leaves combined with LB01 buffer produced clean histograms with sharper peaks, reduced noise, and low coefficient of variation values. FCM analysis effectively classified the nodal explants of N. cadamba treated with colchicine into three distinct groups of polyploid
plants: tetraploids, mixoploids, and octoploids. The N. cadamba tetraploids were found to have an estimated DNA content of 2.59 ± 0.09 pg, while octoploids showed an increase of DNA content to 5.35 ± 0.24 pg. These results highlight the effectiveness of FCM as a valuable tool in identifying mixoploids among the colchicine-induced polyploids of N. cadamba, as compared to the conventional method of chromosome counting. Mixoploids, which are characterized by cells with varying ploidy levels, deserve further investigation in future research.

To ensure high quality and efficient field production, the industry relies on a uniformity of elite cocoa plants, which can be achieved through vegetative propagation methods like somatic embryogenesis. However, the low yield rate in the multiplication and regeneration of cocoa plants remains a challenge for basic research. To obtain a greater number of secondary somatic embryos (SSE) in cocoa, the effect of three osmoregulators on the disc cells of primary somatic embryos (PSE) of cocoa was studied. PSE was induced from cocoa staminodes of genotype I52. Epicotyls were selected from PSE at the torpedo and cotyledon stages, segmented into 3 mm discs, and placed in a secondary callus growth medium. The explants were transferred to embryo development medium 3, where they were exposed to the osmoregulatory polyethylene glycol (PEG), mannitol, and sorbitol at the following concentrations: 0%, 1%, 3%, and 5%. D-Mannitol at 3% and D-Sorbitol at 1% increased the number of SSE at the torpedo, globular, and cotyledon stage per explant. The culture medium with 1% PEG significantly increased the formation of SSE in the globular and cotyledonal stages. The results presented a positive effect of the osmoregulators on the formation of cocoa SSE.

Establishing a method for rapid and efficient regeneration of E. bungeanus is essential to achieve industrial-scale production. The aim of this study was to establish a rapid tissue propagation technique for E. bungeanus and provide a foundation for the industrial production of tissue-cultured seedlings. Using stem segments of E. bungeanus as explants, we investigated effects of explant collection time, sterilization method, various culture media, and ratios of plant growth regulators on the initiation, subculture, and rooting stages of the tissue culture process for E. bungeanus. The optimal explant collection time was mid-April; a combination of 75% ethanol for 20 s, followed by 0.1% HgCl2 for 7 min was suitable for disinfection, yielding a survival rate of 55.00% for the explants. Initiation culture using the woody plant medium (WPM) supplemented with 1.0 mg L-1 of 6-benzylaminopurine (6-BA) and 0.2 mg L-1 of α-naphthalene acetic acid (NAA) achieved an induction rate of 87.22% for explants. Proliferation culture on ¼ WPM medium containing 2.0 mg L-1 of 6-BA and 0.1 mg L-1 of NAA resulted in a propagation coefficient of 4.98. Rooting culture on ½ Murashige and Skoog (MS) medium supplemented with 0.2 mg L-1 of indole-3-butyric acid achieved a rooting rate of 78.33%. However, the rooting rate was low, indicating the need for further optimization of rooting and acclimatization. This study is the first to develop a rapid and efficient regeneration system for E. bungeanus using stem segments.
