The genetic relationships of A genomes of Triticum urartu (Au) and Triticum monococcum (Am) in polyploid wheats are explored and quantified by AFLP fingerprinting. Forty-one accessions of A-genome diploid wheats, 3 of AG-genome wheats, 19 of AB-genome wheats, 15 of ABD-genome wheats, and 1 of the D-genome donor Ae. tauschii have been analysed. Based on 7 AFLP primer combinations, 423 bands were...

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 diploid species that donated the A and D genomes to the polyploid wheats have been recognized for some time. New evidence indicates that Triticum speltoides cannot be the B genome donor to T. turgidum or T. aestivum. T. speltoides is probably homologous to the G genome of T. timopheevii. The donor of the B genome to T. turgidum and T. aestivum is currently unrecognized.

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,...

Giacintucci V., Guardeño L., Puig A., Hernando I., Sacchetti G., Pittia P. (2014): Composition, protein contents, and microstructural characterisation of grains and flours of emmer wheats (Triticum turgidum ssp. dicoccum) of the central Italy type. Czech J. Food Sci., 32: 115–121. The microstructural characteristics were evaluated of two types of Italian Farro (Triticum turgidum ssp. dicoccum) ...

Wheat-derived foodstuffs represent about one-fifth of the calories consumed by humans worldwide. Bread wheat (Triticum aestivum L.) is one of the most important crops throughout the world, and it has been extensively studied for its allelopathic potential. In contrast, for allelopathy in durum wheat (Triticum turgidum ssp. durum), our knowledge is partial and fragmentary. Through highlighting r...

Aiganfanmai is a dwarf tetraploid wheat landrace (Triticum turgidum var. turgidum) that stably produces the semi-dwarf trait. Plant height varies from 80-105 cm under cultivation. Compared with tall durum wheat (T. turgidum var. durum) variety Langdon, we found it to have short spikes and seeds, besides a semi-dwarf character. We crossed Aiganfanmai with Langdon to analyze the genetic basi...

The collection of 10 parental lines of tetraploid wheat genotypes with various origin was cultivated in growth chamber. Leaf and growth traits such as assimilation pigments content, dry mass and leaf area of plants were measured. The genotype differences were recognized by chlorophyll a fluorescence fast kinetics method applied on penultimate young wheat leaves. Consequently, heat stress suscep...

Dear Editor, We read with interest the article by Gorelick et al. [1], who assayed the diabetogenic potential of two ancestral wheat landraces (Triticum turgidum ssp. dicoccoides and spp. dicoccum), compared to a modern wheat cultivar (T. aestivum) in NOD mice. [...].

Wheat bugs are widely distributed in various areas of Europe, Asia and North Africa. Species belonging to the genus Eurygaster and Aelia pierce wheat kernels affecting protein quality. The effects of these insects’ feeding activity have been studied mainly in bread wheat (Triticum aestivum L.). This study provides information on the degradation of prolamin proteins (glutenins and gliadins) of b...
