Nutritional deficiency and the inability of this mushroom to efficient use of compost are mentioned as its reasons. Basically, compost includes two major food components, lignocellulose and microbial biomass. But this microbial biomass provides just 10% of button mushroom food needs. According to research studies, differentenzymes in both white button mushroom and oyster mushroom are responsible for decomposition of lignin compounds in compost media, from begin of mycelium grows to the end of fruiting. Lacasse, manganese peroxidase, lignin peroxidase, glyoxal oxidase enzymes contribute to degradation of lignin compounds in degradation mushroom has proven by researchers however itis dependent on mushroom types. Manganese peroxidase enzyme (EC. 1.11.1.13) is an extracellular parser lignin enzyme that has a central peroxidase core. Manganese peroxidase enzyme oxidizesMn2+ to Mn3+ and then Mn3+...

The yield of this mushroom is less than the average of yield in the world because of strain degeneration and using strains with low yield. Most of the current hybrids are either identical or very similar to the first hybrids. Ongoing breeding programs are exploiting the variability in Agaricus germplasm to produce new varieties with better traits including higher yield and resistance to biotic and abiotic stresses. One of the breeding programs is F1 production from parental homokaryons crossing. These homokaryonsis were isolated among germinated basidiospores on the culture media. During the last decades, various molecular markers based on nucleic acid polymorphisms (such as Restriction Fragment Length Polymorphism, Random Amplification of Polymorphic DNA, Amplified fragment of Length Polymorphism, Inter Simple Sequence Repeat, Simple Sequence Repeat markers) have ...

Edible mushrooms are a rich source of protein. Agaricus bisporus is the most common edible mushroom with high economic value. One of the most important steps in the production process of white button mushroom is the production of spawn. It is highly important to make pure high-quality mycelium during the production of spawn. Studies have shown that at this stage of production, a high level of morphological changes occurs in some mushrooms, which causes the formation of fluffy-shaped mycelium. This phenomenon is a kind of strain degeneration in edible mushrooms and is one of the biggest concerns of the producers of white button mushroom. Objectives: The purpose of this study was to investigate the nature of stroma (strain degeneration) in white button mushroom, and to identify the causes of genetic changes. Methods: In this experiment, ten successive subcu...

In this report, a few methods of total RNA Extraction from Edible mushroom (Agaricus bisporus) compared. This methods consist AGPC(Acid Guanidinium-Phenol-Chloroform), The method according by Lithium chloride and RNx total RNA isolation Kit (CinnaGen). Best method selected for the preparation of high quality and intact total RNA from A. bisporus. Based on the Ethidium Bromide straining pattern of 28s and 18s rRNAs, either denaturing (formaldehyde/agarose) or nondenaturing (TAE/agarose) gel electrophoresis could be used to determine the general integrity of the RNA preparation. Analysis by either method revealed sharp rRNA bands indicative of high quality RNA. yield of RNA was acceptable in any three method but RNA quality in AGPC method similar with RNx Total RNA isolation kit (CinnaGen).

To achieve constant interested gene expression in all cells of the organism, proper promoter isolation is necessary. To isolate this promoter, PCR with specific primers was performed on extracted DNA of the white button mushroom strains Holland737 and IM008. The PCR amplified 290 bp fragments of gpdII promoters. IM008 gpdII promoter was used to construct pCAMBIAH8 plasmid. Comparison of isolated promoters among sequence records at NCBI demonstrated high similarity between IM008 gpdII promoter and previously reported gpdII promoter. Sequence analysis of isolated promoters revealed several point mutations on this promoter. TACAAA promoter sequence in −65 site acts as TATA box. Among the three CAAT candidate sequences, one is functional, which is located at position −108. ...

Phytoestrogens derived from medicinal plants would be the best alternative to chemical drugs with harmful side effects. The main purpose of the present study was to investigate the effect of ferutinin compared to 17β-estradiol (E2) on bone mineralization of zebrafish larvae. Regarding the lack of publications, the histology analysis was performed after exposure to E2 to find effective treatment on bone mineralization of developing zebrafish larvae. Then, the larvae were exposed to four concentrations of ferutinin at three time points to assess the mortality, the expression of some related genes and histology of the ceratohyal and hyomandibular of treated larvae. The RT-PCR result of the treatment groups demonstrated the similar expression pattern in the larvae which were exposed to 1.25 μg/mL of ferutinin and 2 µM of E2 at 2 dpf, which confirmed the result of histology analysis. ...

Five normal trees were selected from the Guilan region, Iran. Samples for testing were prepared at four stem height levels (5%, 25%, 50% and 75% of total stem height) in both positions along radial direction (heartwood and sapwood). Analysis of variance results (Anova) indicated that the effects of longitudinal position (stem height) and heartwood-sapwood on the wood density, MOE and MOR were significant. The mean of wood density, MOE and MOR along longitudinal position from base to top decreased with height. The mean of wood density, MOR and MOE in sapwood are lower compared to the corresponding values for heartwood. The relationship between wood density and mechani...

In this study, two of the species ate introduced for the first time. Due to the extreme similarities and the wide variation of the morphological characters, identification of these species is very difficult. In this study, we attempted to separate the species using morphological characters. We scored 75 morphological (vegetative and generative) characters of 84 individuals belonging to 11 species. The results of the multivariate analysis indicated the separation among the studied species and showed three distinct groups among samples. The first group was individuals of E. repandum, E. griffithianum, E. sisymbrioides, E. nanum and E. persepolitanum. The second group included individuals of E. aitchisonii, E. kerbabaevii and E. crassipes. The third group consisted of E. crassicaule, E. stocksianum, E. crassicaule (with trichome) and E. ischnostylum. Finally, an identification key was introduced based on morphological characters for Erysimum species in Khorasan.

Among Iranian species, five are found in the Razavi, North and South Khorasan provinces. Eighty morphological characters were measured in 44 herbarium specimens belonging to: H. calycinus, H. bituminosus, H. platystegius and H. elegans. The Kruskal-Wallis Test was implemented to evaluate which characters significantly differentiate the species. Thus, forty-two morphological characters were used in subsequent analyses. Taxonomic relationships were investigated using the Principal Component Analysis (PCA). H. bituminosus and H. platystegius were separated in two distinct groups. There was no sharp distinction between the two other species, H. calycinus and H. elegans. Canonical discriminant analysis (CDA) was also applied to find the best discriminating traits among the species.

For this purpose, the bagasse flour was mixed with 25, 35, and 45 wt.% of polypropylene. An MAPP coupling agent was also used. The tensile strength and impact resistance tests were conducted according to the ASTM standard. It was found that the tensile properties improved, but the impact strength decreased with increase in the bagasse fiber loading from 25 to 45%. The composites treated with MAPP exhibited enhanced mechanical properties, which pointed to an efficient fiber-matrix adhesion.
