In this study, ITS–rDNA region was used to identify some anamorphic powdery mildews in Guilan province. According to the results, Erysiphe species on Vicia faba and Sesbania punicea showed 100% similarity to each other, however, without ITS sequence of holotype of E. sesbaniae it is impossible to make conclusion whether Vicia faba powdery mildew fungus actually belongs to E. sesbaniae or E. tri...

many powdery mildew fungi occur as anamorphic state on different host plants in guilan province, iran. the species have usually been identified as oidium spp. in order to identify teleomorphic species using anamorphic characteristics and host range, several infected plant specimens were collected from around guilan province during 2004-2011. based upon  the  results of the study 25 species were...

Three different techniques were applied to analyze the patterns of longitudinal chromosome differentiation in five Sesbania species (S. exasperata, S. punicea, S. sesban, S. tetraptera, and two different geographical populations of S. virgata). For all the species investigated, the prophase chromosome condensation was always proximal. After staining with the fluorochromes chromomycin A, and DAP...

The objective of the study was to evaluate biometry fruits and seeds S. punicea in order determine point collection for production seedlings species. were collected from plants situ Barra do Ribeiro, RS. In laboratory, they separated by staining in: stage 1, 2 3. Fruits measured with digital caliper (mm), counting number locules. At each water content, seed dry matter germination test evaluated...

A well-resolved rhizobial species phylogeny with 51 haplotypes was inferred from a combined atpD + recA data set using Bayesian inference with best-fit, gene-specific substitution models. Relatively dense taxon sampling for the genera Rhizobium and Mesorhizobium was achieved by generating atpD and recA sequences for six type and 24 reference strains not previously available in GenBank. This phy...
