Understanding of belowground interactions among tree species and the fine root (≤2 mm in diameter) contribution of a species to forest ecosystem production are mostly restricted by experimental difficulties in the quantification of the species composition. The available approaches have various defects. By contrast, DNA-based methods can avoid these drawbacks. Quantitative real-time polymerase c...

this study represents phylogenetic analyses of two woody polygonaceous genera calligonum and pteropyrum using both chloroplast fragment (trnl-f) and the nuclear ribosomal internal transcribed spacer (nrdna its) sequence data. all inferred phylogenies using parsimony and bayesian methods showed that calligonum and pteropyrum are both monophyletic and closely related taxa. they have no affinity w...

We have studied several samples from Lotus corniculatus s. l. and L. zhegulensis populations with the use of SSR sequenced nuclear (ITS) plastid (atpB-rbcL, ndhC-trnV, rpl32-trnL(UAG), trnH-psbA, trnL-trnF) markers. analysed 9 local Volga River valley ranging Ulyanovsk in north to Volgograd south, as well two Moscow Lipetsk Provinces. Analyses markers using STRUCRURE program divided sample into...

The present study was hypothesized to evaluate a set of SSRs for the assessment genetic variations in Asparagus officinalis L. and their allied species. Nine genic SSR markers were especially developed genome employed DNA profiling studies These have revealed allelic polymorphism ranging from 1.0 2.0. Allele frequency found highest psbD-trnL (1.0), petB (1.0) AG7 while it lowest ZHD1 (0.1). Pol...

Phenotypic and genotypic diversity is essential needs more enhancement in different ways to achieve higher productivity better quality vegetables. The presented research aimed study the phenotypic characteristics determine genetic of F1 populations compared with colchicine mutant variants Mercy cultivar cucumber (Cucumis sativus L.), held from March May 2019 at experimental field Department Agr...
