The pollen morphology of 48 taxa (including species, subspecies and varieties) of the genus Lamium was investigated and documented using light microscopy (LM) and scanning electron microscopy (SEM). Lamium pollen is small to medium sized ( P = 21.65–39.96 μm), oblate-spheroidal to subprolate in shape and tricolpate. Three major exine sculpturing patterns (reticulate, granulate and microreticulate) were observed. The results indicated that the exine sculpturing pattern of Lamium is systematically informative at sectional level, but not at the species and infraspecific levels. In the present study, the palynological data are compared with available phylogenetic studies to evaluate the systematic value of pollen characters in the genus. Analysis show that; (1) Mennema's infrageneric classification is partly corroborated by our palynological data, (2) recent phylogenetic analysis on the genus and our results are partly corroborated, and (3) pollen morphology supports the inclusion of L. galeobdolon (= Galeobdolon ), L. orientale and L. multifidum (= Wiedemannia ) in Lamium . (4) Variation in exine sculpturing pattern have systematic importance particularly at sectional level.

Parallel to this increase, hardware, software and trained people structures started to develop. This progress enabled the preparation of some countrywide digital databases to be used in spatial analysis and modeling processes. Flora and vegetation studies took the benefit of these improvements, and some applications showed the emerging utility of these tools. In this presentation, we summarized two latest innovations of us that can be used for plant biodiversity and community composition mapping. In the former, we explained how plant biodiversity of Nallihan forest ecosystem was modeled and mapped in GIS by utilizing diversity (Shannon Wiener, Simpson, Number of Species) indices, environmental (soil, topography, geology and climate) variables, and remotely sensed data (LANDSAT-ETM+). In the latter, we summarized the ways of Normalized Difference Vegetation Index (NDVI) usage to develop plant community composition maps of Tersakan Valley in Amasya by using both GIS and RS.

Palynological characteristics of 30 Salvia taxa in sections Hymenosphace and Aethiopis from Turke... more Palynological characteristics of 30 Salvia taxa in sections Hymenosphace and Aethiopis from Turkey were investigated by light and scanning electron microscopy. S. aethiopis (sect. Aethiopis) has the smallest pollen while S. blepharochlaena (sect. Hymenosphace) has the largest pollen. The basic shape of the pollen grains in most taxa is suboblate, oblate-spheroidal, or prolate-spheroidal to spheroidal; however, subprolate pollen grains are occasionally are found in S. cassia of sect. Aethiopis. Hexacolpate pollen is dominant in all studied taxa, but heptacolpate and octacolpate pollen grains are mixed together in S. palaestina (heptacolpate, 20%) and S. candidissima subsp. candidissima (heptacolpate, 2% and octacolpate, 40%). The exine sculpturing is bireticulate (the common type) or reticulate-perforate. The bireticulate and the reticulate-perforate sculpturing patterns can be divided into subtypes according to the number of primary lumina. Taxonomic implications of the pollen data are also discussed.

Some anatomical characters such as (1-)2-24-rowed pith rays in roots, dorsiventral leaves, obviously larger upper epidermal cells, and two to three large vascular bundles in the center and two to four small subsidiary bundles in the wings of petiole provide information of taxonomical significance. Three main types of trichomes were observed on the stem, inflorescence axis, leaf and calyx surfaces of S. chrysophylla. They are peltate, capitate glandular and nonglandular. Capitate glandular and non-glandular trichomes were further subdivided into several kinds. Glandular trichomes are present in abundance on the inflorescence axis and calyx, but non-glandular ones were mainly situated on the leaf and stem. Scanning Electron Microscopy (SEM) studies on the pollen grains have revealed that they are oblate-spheroidal and their exine ornamentation is bireticulate-perforate.

Since 2005, our revisional studies on the genus in Turkey have been shown that previously known two localities of the species including type locality are wrong, and the species has not been collected since 1970. In this study, the type locality of the species is amended and morphological description of the species is amplified and expanded based on large number of specimens. The anatomy, palynology, myxocarpy, mericarp micromorphology and distribution of the trichomes on the aerial parts of S. quezelii are studied for the first time to understand the usefulness of these characteristics for systematic purposes. Morphological characteristics of leaves, calyces, corollas and types of stamens are useful for sectional and specific delimitation in Salvia. Anatomical characters such as number of ray rows in roots, distance between vascular bundles in stems, mesophyll structures in leaves, shape of mid-rib and presence/absence of sclerenchymatic tissue in petioles provide information of taxonomical significance. Scanning electron microscopy studies on the pollen grains have revealed that they are oblate-spheroidal to prolate-spheroidal and their exine ornamentation is reticulate-perforate. Mericarps are broadly ovate to rotund, and surface sculpturing pattern is verrucate or slightly reticulate. Three main types of trichomes were observed on the stem, inflorescence axis, leaf and calyx surfaces of S. quezelii with very high diversity. They are peltate, capitate glandular and non-glandular. Capitate glandular and non-glandular trichomes were further subdivided into several kinds. Glandular trichomes are present in abundance on all vegetative parts, particularly in inflorescence axis.

Research paper thumbnail of Pollen morphology of some taxa of Vicia L. subgenus Vicilla (Schur) Rouy (Fabaceae) from Turkey

Plant Systematics and Evolution, 2014

Twelve morphometric characters are analysed with one-way analysis of variance and Tukey&#39;s honestly significant difference test for multiple comparisons. Polar axis and equatorial diameter of pollen grains range from 24.64 to 44.19 and from 15.90 to 30.42 mu m, respectively. The pollen grains are prolate-spheroidal to perprolate (P/E = 1.09-2.07), but the prolate shape occurs in the majority of the taxa. The regular pollen grains of all taxa are trizonocolporate, isopolar, and released in monads. Ornamentation of the mesocolpium is psilate-perforate in V. tenuifolia subsp. dalmatica and V. tenuifolia subsp. tenuifolia (sect. Cracca), reticulate-rugulate in V. villosa subsp. villosa (sect. Cracca), and reticulate-perforate in the remaining taxa. The apocolpium and colpus area are reticulate-perforate in V. hirsuta (sect. Cracca), V. ervilia (sect. Ervilia) and V. lunata subsp. grandiflora (sect. Trigonellopsis), and psilate, psilate-slightly perforate or perforate in the other taxa. The results obtained from analyses of pollen grains from the studied taxa of the subgenus Vicilla reveal significant differences in general morphology and some morphometric attributes, and ornamentation types. However, it is concluded that pollen morphology has proved to be uninformative for differentiating the subgenera Vicilla and Vicia.

In Turkey, Hordeum is represented by 12 taxa, namely Hordeum violaceum Boiss. & Hohen., H. geniculatum All., H. marinum var. marinum, H. marinum Hudson var. pubescent (Guss.) Nevski, H. murinum L. subsp. murinum, H. murinum subsp. glaucum (Steudel) Tzvelev, H. murinum subsp. leporinum (Link) Arc. var. leporinum, H. murinum subsp. leporinum var. simulans Bowden, H. bulbosum L., H. spontaneum K.Koch, H. distichon L., and H. vulgare L. Th e main objective of this study is to assess the signifi cance of anatomical characteristics of the leaves. For this purpose, dehydrated specimens were embedded into paraffi n and transverse sections were gathered. Furthermore, the leaf surfaces were examined. Results of the study show that anatomical characteristics of the leaf blades vary between the taxa in both qualitative and quantitative values. Sclerenchymatic cells, silica bodies, and stomata, furrow and rib properties, the existence of midrib and bulliform cells, and indumentum properties such as arrangement, density, and length of macro hairs are all included in these diagnostic characteristics. Based on these anatomical characteristics, an identifi cation key for the taxa is given for the fi rst time.

In our previous study of 55 Salvia taxa, we explored significant anticholinesterase activity of cultivated S. fruticosa. In this study, we compared the inhibitory activity of dichloromethane, ethyl acetate, and ethanol extracts of 3 wild-grown samples and 1 cultivated sample of S. fruticosa against acetylcholinesterase and butyrylcholinesterase enzymes (which are associated with pathogenesis of Alzheimer&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s disease) by using the spectrophotometric Ellman method. Antioxidant activities were assessed by determining 2,2-diphenyl-1-picrylhydrazyl radical-scavenging activity, iron-chelating capacity, and ferric-reducing antioxidant power. The dichloromethane extract of the cultivated sample was then subjected to fractionation by using open column chromatography and medium-pressure liquid chromatography to obtain the most active fraction by activity-guided fractionation. All fractions and subfractions were tested in the same manner, and inactive subfractions were discarded. The essential oil of the cultivated sample was analyzed by gas chromatography-mass spectrometry.

Some anatomical characters such as (1-)2-24-rowed pith rays in roots, dorsiventral leaves, obviously larger upper epidermal cells, and two to three large vascular bundles in the center and two to four small subsidiary bundles in the wings of petiole provide information of taxonomical significance. Three main types of trichomes were observed on the stem, inflorescence axis, leaf and calyx surfaces of S. chrysophylla. They are peltate, capitate glandular and nonglandular. Capitate glandular and non-glandular trichomes were further subdivided into several kinds. Glandular trichomes are present in abundance on the inflorescence axis and calyx, but non-glandular ones were mainly situated on the leaf and stem. Scanning Electron Microscopy (SEM) studies on the pollen grains have revealed that they are oblate-spheroidal and their exine ornamentation is bireticulate-perforate.

Since 2005, our revisional studies on the genus in Turkey have been shown that previously known two localities of the species including type locality are wrong, and the species has not been collected since 1970. In this study, the type locality of the species is amended and morphological description of the species is amplified and expanded based on large number of specimens. The anatomy, palynology, myxocarpy, mericarp micromorphology and distribution of the trichomes on the aerial parts of S. quezelii are studied for the first time to understand the usefulness of these characteristics for systematic purposes. Morphological characteristics of leaves, calyces, corollas and types of stamens are useful for sectional and specific delimitation in Salvia. Anatomical characters such as number of ray rows in roots, distance between vascular bundles in stems, mesophyll structures in leaves, shape of mid-rib and presence/absence of sclerenchymatic tissue in petioles provide information of taxonomical significance. Scanning electron microscopy studies on the pollen grains have revealed that they are oblate-spheroidal to prolate-spheroidal and their exine ornamentation is reticulate-perforate. Mericarps are broadly ovate to rotund, and surface sculpturing pattern is verrucate or slightly reticulate. Three main types of trichomes were observed on the stem, inflorescence axis, leaf and calyx surfaces of S. quezelii with very high diversity. They are peltate, capitate glandular and non-glandular. Capitate glandular and non-glandular trichomes were further subdivided into several kinds. Glandular trichomes are present in abundance on all vegetative parts, particularly in inflorescence axis.

Twelve morphometric characters are analysed with one-way analysis of variance and Tukey&#39;s honestly significant difference test for multiple comparisons. Polar axis and equatorial diameter of pollen grains range from 24.64 to 44.19 and from 15.90 to 30.42 mu m, respectively. The pollen grains are prolate-spheroidal to perprolate (P/E = 1.09-2.07), but the prolate shape occurs in the majority of the taxa. The regular pollen grains of all taxa are trizonocolporate, isopolar, and released in monads. Ornamentation of the mesocolpium is psilate-perforate in V. tenuifolia subsp. dalmatica and V. tenuifolia subsp. tenuifolia (sect. Cracca), reticulate-rugulate in V. villosa subsp. villosa (sect. Cracca), and reticulate-perforate in the remaining taxa. The apocolpium and colpus area are reticulate-perforate in V. hirsuta (sect. Cracca), V. ervilia (sect. Ervilia) and V. lunata subsp. grandiflora (sect. Trigonellopsis), and psilate, psilate-slightly perforate or perforate in the other taxa. The results obtained from analyses of pollen grains from the studied taxa of the subgenus Vicilla reveal significant differences in general morphology and some morphometric attributes, and ornamentation types. However, it is concluded that pollen morphology has proved to be uninformative for differentiating the subgenera Vicilla and Vicia.

In Turkey, Hordeum is represented by 12 taxa, namely Hordeum violaceum Boiss. & Hohen., H. geniculatum All., H. marinum var. marinum, H. marinum Hudson var. pubescent (Guss.) Nevski, H. murinum L. subsp. murinum, H. murinum subsp. glaucum (Steudel) Tzvelev, H. murinum subsp. leporinum (Link) Arc. var. leporinum, H. murinum subsp. leporinum var. simulans Bowden, H. bulbosum L., H. spontaneum K.Koch, H. distichon L., and H. vulgare L. Th e main objective of this study is to assess the signifi cance of anatomical characteristics of the leaves. For this purpose, dehydrated specimens were embedded into paraffi n and transverse sections were gathered. Furthermore, the leaf surfaces were examined. Results of the study show that anatomical characteristics of the leaf blades vary between the taxa in both qualitative and quantitative values. Sclerenchymatic cells, silica bodies, and stomata, furrow and rib properties, the existence of midrib and bulliform cells, and indumentum properties such as arrangement, density, and length of macro hairs are all included in these diagnostic characteristics. Based on these anatomical characteristics, an identifi cation key for the taxa is given for the fi rst time.

In our previous study of 55 Salvia taxa, we explored significant anticholinesterase activity of cultivated S. fruticosa. In this study, we compared the inhibitory activity of dichloromethane, ethyl acetate, and ethanol extracts of 3 wild-grown samples and 1 cultivated sample of S. fruticosa against acetylcholinesterase and butyrylcholinesterase enzymes (which are associated with pathogenesis of Alzheimer&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s disease) by using the spectrophotometric Ellman method. Antioxidant activities were assessed by determining 2,2-diphenyl-1-picrylhydrazyl radical-scavenging activity, iron-chelating capacity, and ferric-reducing antioxidant power. The dichloromethane extract of the cultivated sample was then subjected to fractionation by using open column chromatography and medium-pressure liquid chromatography to obtain the most active fraction by activity-guided fractionation. All fractions and subfractions were tested in the same manner, and inactive subfractions were discarded. The essential oil of the cultivated sample was analyzed by gas chromatography-mass spectrometry.
