Three novel low-molecular-weight glutenin subunit (LMW-GS) genes (designated as Ht1, Ht2, and Ht3) were isolated from the genomic DNA of Hordeum brevisubulatum ssp. turkestanicum by PCR amplification (accession no. Y0695). The coding regions of Ht1, Ht2, and Ht3 were 924, 924, and 903 bp, respectively. The deduced amino acid sequences were 306, 306, and 299(More)
The low-molecular-weight (LMW) glutenin subunits are important for the aspects of wheat quality and dough processing, and the LMW-i type glutenin is one of the typical glutenins. However, a detailed description of the DNA structures and encoded polypeptides of the LMW-i type glutenin subunit gene family is still lacking. In this study, two LMW-i type(More)
Three low-molecular-weight (LMW) glutenin-like genes (designated as Ssy1, Ssy2, and Ssy3) from Secale sylvestre Host were isolated and characterized. The three genes consist of a predicted highly conservative signal peptide with 20 amino acids, a short N-terminal region with 13 amino acids, a highly variable repetitive domain and a less variable C-terminal(More)
To carry out comparative analysis of the α-gliadin genes on A genomes of diploid and polyploid wheats, 8 full-length α-gliadin genes, including 3 functional genes and 5 pseudogenes, were obtained from diploid wheats, among which 2, 2 and 4 α-gliadin genes were isolated from T. urartu, T. monococcum, and T. boeoticum, respectively. The results indicated that(More)
Using microsatellite (SSR) markers, the genetic diversity and genetic relationships among 48 Triticum turgidum L. accessions, including 30 Triticum turgidum L. ssp. turgidum, 7 Triticum turgidum L. ssp. durum, 4 Triticum turgidum L. ssp. carthlicum, 3 Triticum turgidum L. ssp. paleocolchicum, 2 Triticum turgidum L. ssp. turanicum, and 2 Triticum turgidum L.(More)
Sixty-two DNA sequences for the coding regions of omega-secalin (ω-secalin) genes have been characterized from rye (Secale cereale L.), hexaploid and octoploid triticale (×Triticosecale Wittmack), and wheat (Triticum aestivum L.) 1BL/1RS translocation line. Only 19 out of the 62 ω-secalin gene sequences were full-length open reading frames (ORFs), which can(More)
Allelic variation of the low-molecular-weight glutenin subunit (LMW-GS) is associated with the significant differences of dough quality in bread and durum wheat, and has been widely evaluated at protein level in wheat and its relatives. In this study, a PCR primer set, targeting the high variable repetitive domains, was employed to assay the length(More)
