The medicinal credence of Spigelia anthelmia suggests the plant as an important herbal remedy in the treatment of asthma and helminthiasis. A valid pharmacognostic assessment is done to give a standard and quality identification of the medicinal plant. A fresh leaf and a powdered form were evaluated. The foliar micro-morphology (qualitative and quantitative), microscopy, chemo-microscopy, and phytochemical composition were assessed using standard methods. The result indicates that for micromorphology, the cells are rectangular to polygonal with very large cells for both abaxial and adaxial epidermis. It has a straight anticlinal wall. stomata type is anomocytic for both the epidermis which means the leaf is amphistomatic. Trichomes present on the abaxial and adaxial are uniseriate and non-glandular, while they are absent on the adaxial epidermis. The stomata index for abaxial is (10.42%), while for adaxial is (5.88%). The cell length for abaxial (84.55 μm) and adaxial is (81.92 μm), while the cell width for abaxial is (58.15 μm) and for adaxial is (57.85 μm). The cell density is higher on the abaxial with (43.0 μm) and lesser on the adaxial with (32.0 μm). Mean Stomata number on the lower epidermis is (5), while on the adaxial is (2). The macroscopic features identified shows that the leaves are opposite, simple and entire, having a cylindrical shape with horny texture, the bark is coarse and the surface is smooth with a spot of brown nodules. The trunk is simple, without thorns but hairy. The leaf epidermis is straight with numerous starch grains and the crystals of calcium oxalate are present on the abaxial epidermis and absent on the adaxial. It has a granular fracture surface; its color is greyish green with a faint characteristic odor. The chemo-microscopic analysis shows that Starch, calcium carbonate crystals and cellulose are present while lignin, fats, calcium oxalate crystals, and mucilage were absent. The phytochemical screening shows that flavonoid, alkaloid, saponin, phenols, and tannin are present except, cardiac glycoside and anthraquinone. The foliar micromorphology, the macroscopy and phytochemical composition of S. anthelmia have provided proper information for its identification and authentication which can enable it to be included in the official pharmacopeia of Nigerian medicinal plants.

Methylation in DNA and chemical modification in histone proteins are the two most studied epigenetic mechanisms in plants. There exist low-throughput and high-throughput DNA methylation detection techniques in epigenetic research. In this study, touch-down polymerase chain reactions methylation sensitive-random amplified polymorphic DNA (TD-MSRAPD) technique was used to investigate cytosine methylation differences among three cotton varieties; Texas Marker 1 (TM-1), Pima 3-79 (3-79) and Maydos Yerlisi (MY), belonging to Gossypium hirsutum L., G. barbadense L., and G. herbaceum L., respectively. Genomic DNA samples extracted from the mature seeds of these varieties were treated with MspI, a relative methylation-insensitive restriction enzyme and HpaII, a methylation-sensitive restriction enzyme before touch-down polymerase chain reactions. Among 16 oligonucleotide primers used, three primers (AT03, W15, and C08) resulted in methylation polymorphisms among three varieties. TD-MS-RAPD-PCR method was cost-effective, required a simple method and basic instrumentation, and could easily be performed in our laboratory with basic setup using a regular DNA thermal cycler and DNA gel electrophoresis system, however, the level of methylation polymorphisms detected with this method were very low in cotton. We concluded that the low level of polymorphisms among the three cotton species were probably due to low occurrences of CCGG sites within the cotton genome. We also noted that TDMS- RAPD-PCR method could be used in primary scanning studies in epigenetic research.

Linum nervosum is among species that can hybridize with L. usitatissimum and produce fertile offsprings. Genetic diversity analysis of this wild relative of flax is important from conservation and breeding points of view. In the present study, 55 randomly selected plants of six different populations of L. nervosum varieties, including var. nervosum and var. bungei, were studied for morphological and genetic variability as well as population structure. Analysis of variance (ANOVA) did not show significant morphological difference between populations. PCA as well as PCA biplot confirmed that some morphological traits have taxonomic value. UPGMA clustering separated the populations of varieties in two distinct clusters, indicating degrees of morphological differentiation between them. Furthermore, UPGMA confirmed the variability in morphological characters within populations. Neighbor Joining tree and Neighbor-Net analysis of ISSR data revealed inter- and intrapopulation genetic variability. STRUCTURE plot revealed allelic difference of these varieties and some degree of intervarietal gene flow. K-means clustering showed the fragmentation of populations in support of AMOVA test, which revealed significant genetic difference among them. In general, obtained results confirmed the alternation of taxonomic level of L. bungei to the variety of L. nervosum.

Anatomical and karyological features were investigated in four populations of Acinos alpinus subsp. meridionalis (Nyman) P. Ball., an Ibero-Maghreban species. Plant material was collected in the field during flowering stage, in contrasting bioclimatic conditions. Fresh material was used for analysis of trichomes morphology with light microscopy. Young meristems and flower buds were fixed for karyological analysis. Two types of capitate glandular, one type of peltate glandular, and four types of non-glandular trichomes were observed on different parts of the plants, including the stems, leaves and flowers. Trichomes distribution and density showed variability among organs, but no intraspecific variability was found. The chromosome number 2n = 2x = 18 is reported for the first time for Algerian populations. Furthermore, aberrant meiotic behavior in the form of cytomixis was observed in one population of A. alpinus subsp. meridionalis – cytoplasmic strand was formed between more than two cells at different stages of meiosis. Other types of abnormalities such as lagging chromosomes, and formation of triads with microcytes were also discovered. Results are discussed in comparison with literature.

Crepidium acuminatum is largely confine to the Himalayan region although it has been reported in South India, where its presence distribution needs to be critically studied. This study describes the morphological, anatomical and histochemical aspects of the materials of the authenticated species collected from Himalayas. This study also highlights the features of histochemistry and anatomy that should be used for the correct identification and authentication of C. acuminatum, especially because of the therapeutic importance of the species and its possible adulteration by other orchids.

Seed shape quantification in diverse species of the families belonging to the order Cucurbitales is done based on the comparison of seed images with geometric figures. Quantification of seed shape is a useful tool in plant description for phenotypic characterization and taxonomic analysis. J index gives the percent of similarity of the image of a seed with a geometric figure and it is useful in taxonomy for the study of relationships between plant groups. Geometric figures used as models in the Cucurbitales are the ovoid, two ellipses with different x/y ratios and the outline of the Fibonacci spiral. The images of seeds have been compared with these figures and values of J index obtained. The results obtained for 29 species in the family Cucurbitaceae support a relationship between seed shape and species ecology. Simple seed shape, with images resembling simple geometric figures like the ovoid, ellipse or the Fibonacci spiral, may be a feature in the basal clades of taxonomic groups.

Object: Study of symptoms and etiology of oleander tuberculosis causative agents and determination of causes of their appearance in conditions of the closed ground of the greenhouses of Ukraine. Methods: Samples for research were selected in greenhouses of Botanical Garden named after acad. A. V. Fomin from different kinds and forms of oleander (Nerium oleander L.). The microbiological and phytopathological analysis was carried out after K. I. Beltyukova. Biolog GN MicroPlate system was used to identify isolated bacterial strains. Calculations for bacteria identification in relation to genus, species and other taxonomic units are based on the similarity index. Results: On oleander plants, the greatest disease progress shows itself on the branches of the second year of development. Up to 5 bacterial nodes of different sizes can be formed on one branch. Galls can be formed on the leaves both on the upper (62.1%) and lower (37.9%) sides. Bacteria actively spread with water from branches and leaves, especially when spraying plants from a hose. The infection degree of different varieties of oleander was not the same. Such varieties and forms as of Nerium oleander "Album", Nerium oleander "Album Plenum" suffer from bacteriosis the most. Conclusions: For the first time in Ukraine tuberculosis Pseudomonas savastanoi pv. nerii was detected on oleander (Nerium oleander L.). The infection degree of different varieties of oleander was not the same. Nerium oleander "Album", Nerium oleander "Album Plenum", are the most severely leased, Nerium oleander "Flavescens", Nerium oleander "Lacteum" are leased to the lesser extent. The spread of the disease is favored by some methods of this group of plants growing: pruning plants, branches, and leaves bruise.

Floral vasculature and gynoecium architecture were studied in Hyacinthoides italica (L.) Rothm. Each locule shelters two ovules inserted basally and surprisingly supplied by axis bundles only, while lateral bundles of the carpels branch out into strands along the epidermises of septal nectaries. We brought then to the fore an unexpected trade-off between the supply of upper ovules in H. non-scripta and that of secretory tissues in the studied species. Moreover, a new pattern of septal nectary is described, with outer and inner cavities.

Results of an analysis and generalization of data on participation of pollen grains of Plantago species (Plantaginaceae) in the collective pollen floras of the Allerod–Holocene deposits of the forest, forest-steppe and steppe zones of Ukraine are considered. Five model species (P. lanceolata, P. major, P. maxima, P. media and P. urvillei) were identified. It has been found that each of model species had its own individual history of distribution in the plain part of Ukraine during the Allerod–Holocene, which was caused by natural and anthropogenic factors. For pollen grains of each model taxon of Plantago, a set of quantitative and qualitative diagnostic characters has been provided, which should be taken into account in their identification during the palynological studies of the Pleistocene–Holocene deposits of Ukraine and adjacent territories.
