Sequencing was used to investigate the origin of the D genome of the allopolyploid species Triticum aestivum and Aegilops cylindrica. A 247-bp region of the wheat D-genome Xwye838 locus, encoding ADP-glucopyrophosphorylase, and a 326-bp region of the wheat D-genome Gss locus, encoding granule-bound starch synthase, were sequenced in a total 564 lines of hexaploid wheat (T. aestivum, genome AABB...

The Russian wheat aphid, Diuraphis noxia, an invasive phytotoxic pest of wheat, Triticum aestivum, and barley, Hordeum vulgare, causes huge economic losses in Africa, South America, and North America. Most acceptable and ecologically beneficial aphid management strategies include selection and breeding of D. noxia-resistant varieties, and numerous D. noxia resistance genes have been identified ...

Common bread wheat, Triticum aestivum, has one of the most complex genomes known to science, with 6 copies of each chromosome, enormous numbers of near-identical sequences scattered throughout, and an overall haploid size of more than 15 billion bases. Multiple past attempts to assemble the genome have produced assemblies that were well short of the estimated genome size. Here we report the fir...

Kernel texture (‘hardness’) is an important trait that determines end-use quality of wheat (Triticum aestivum L. and Triticum turgidum ssp. durum [Desf.] Husn.). Variation in texture is associated with the presence/absence or sequence polymorphism of two proteins, puroindoline a and puroindoline b. This work describes the flanking and coding region sequences of puroindoline genes from 25 access...

The presented study analyzed the inheritance via heterosis of interspecific F1 hybrids between durum and bread wheat over better parents ratios dominance for spike-related traits affecting their productivity transmission to future segregating populations. research transpired in crop seasons 2017–-2019 at Institute Molecular Biology Biotechnologies, Azerbaijan National Academy Sciences, Baku, Az...

The phytotoxicity of Se(IV) was determined through root and shoot growth inhibition, biomass (dry (DM), fresh (FM)) production, water content, photosynthetic pigment (chlorophyll a, chlorophyll b and carotenoids) levels and Se accumulation in the roots and shoots. The sensitivities of monocotyledonae (Hordeum vulgare, Triticum aestivum) and dicotyledonae plants (Sinapis alba, Brassica napus) we...

Long non-coding RNAs (lncRNAs) are a family of regulatory RNAs that play essential role in the various developmental processes and stress responses. Recent advances in sequencing technology and computational methods enabled identification and characterization of lncRNAs in certain plant species, but they are less known in Triticum aestivum (bread wheat). Herein, we analyzed 52 RNA seq data (>30...

Triticum genus encloses several tetraploid species that are used as genetic stocks for expanding the genetic variability of wheat (Triticum aestivum L.). Although the T. aestivum (2n = 6x = 42, AABBDD) and T. durum (2n = 4x = 28, AABB) karyotypes were well examined by chromosome staining, Giemsa C-banding and FISH markers, other tetraploids are still poorly characterized. Here, we established a...

Human history was transformed with the advent of agriculture in the Fertile Crescent with wheat as one of the founding crops. Although the Fertile Crescent is renowned as the center of wheat domestication, archaeological studies have shown the crucial involvement of Çatalhöyük in this process. This site first gained attention during the 1961-65 excavations due to the recovery of primitive hexap...

Restriction map variation in two 5-6-kb chloroplast DNA regions of five diploid Aegilops species in the section Sitopsis and two wild tetraploid wheats, Triticum dicoccoides and Triticum araraticum, was investigated with a battery of four-cutter restriction enzymes. A single accession each of Triticum durum, Triticum timopheevi and Triticum aestivum was included as a reference. More than 250 re...
