PCR-based rye (Secale cereale L.) chromosome-specific markers can contribute to the effective utilization of elite genes of rye in wheat (Triticum aestivum L.) breeding programs. In the present study, 578 new PCR-based rye-specific markers have been developed by using specific length amplified fragment sequencing (SLAF-seq) technology, and 76 markers displayed different polymorphism among rye K...

Tetrameric inhibitors of heterologous alpha-amylases have been characterized in allohexaploid wheat, Triticum aestivum (genomes AABBDD), as well as in Triticum turgidum (AABB) and Triticum tauschii (DD). Their subunits have been identified as the previously described CM proteins. Single oligomeric species were observed in T. Turgidum (subunits CM2, CM3A, and CM16) and in T. tauschii (CM1, CM3D,...

The article analyzes our own data and from the literature on study of plant–pathogen interactions in pathosystem Puccinia triticina host plants genera Triticum Aegilops with different ploidy genomes. We characterize long-term variability Russian populations pathogen, caused by cultivation genetically protected cultivars common wheat (T. aestivum). Differences pathogen’s virulence hexaploid spec...

Phytoremediation is a technology that uses vegetation to remediate contaminants from water, soil, and sediments. Unlike traditional remediation techniques such as soil washing or vitrification, phytoremediation offers a technology that is solar-driven, aesthetically pleasing, and cost effective. Recent studies indicate that winter wheat (Triticum aestivum L.) is a potential accumulator for heav...

Blue aleurone is a useful and interesting trait in common wheat that was derived from related species. Here, transcriptomes of blue and white aleurone were compared for isolating Blue aleurone 1 (Ba1) transferred from Thinopyrum ponticum. In the genes involved in anthocyanin biosynthesis, only a basic helix-loop-helix (bHLH) transcription factor, ThMYC4E, had a higher transcript level in blue a...

The classic wheat evolutionary history is one of adaptive radiation of the diploid Triticum/Aegilops species (A, S, D), genome convergence and divergence of the tetraploid (Triticum turgidum AABB, and Triticum timopheevii AAGG) and hexaploid (Triticum aestivum, AABBDD) species. We analyzed Acc-1 (plastid acetyl-CoA carboxylase) and Pgk-1 (plastid 3-phosphoglycerate kinase) genes to determine ph...

The second largest BamHI fragment (B2) of the chloroplast DNA in Triticum (wheat) and Aegilops contains a highly variable region (a hotspot), resulting in four types of B2 of different size, i.e. B2l (10.5kb), B2m (10.2kb), B2 (9.6kb) and B2s (9.4kb). In order to gain a better understanding of the molecular nature of the variations in length and explain unexpected identity among B2 of Ae. ovata...

Auxin, one of the most important phytohormones enhances the root architecture, nutrient acquisition and plant growth. Present study provides the screening, characterization and optimization of auxin producing bacteria from wheat rhizosphere. Effects of auxin producing isolates on seed germination and growth of T. aestivum were also evaluated. The Bacillus megaterium, Escherichia coli, Klebsiell...
