As shown in Table 1, based upon the occurrence of the four major T-cell immunogenic peptides, as well as the relative lengths of the two polyglutamine domains, the deduced protein sequences of 8 genes (Z4A-3, Z4A-4, Z4A-6, Z4A-8, Z4A-13, Z4A-18, Z4A-21 and Z4A-22) that contained
only glia-α9 and glia-α20 Pifithrin-�� solubility dmso showed that the number of glutamine residues in their glutamine repeat I was relatively large, except for Z4A-22. They could accordingly be assigned to chromosome 6A based on these observations. Similarly, six other α-gliadin genes (Z4A-1, Z4A-2, Z4A-9, Z4A-11, Z4A-12 and Z4A-17) were assigned to chromosome 6B because their amino acid sequences contained none of the four major T-cell epitopes and, except for Z4A-2, carried relatively large numbers of glutamine residues in glutamine repeat II. The remaining 8 genes (Z4A-5, Z4A-7, Z4A-10, Z4A-14, Z4A-15, Z4A-16, Z4A-19 and Z4A-20) contained 2 to 4 epitopes in different combinations. Moreover,
even repeats of glia-α2 were identified in the N-terminal repetitive domain of Z4A-5, resulting from an extra insertion of QLPYPQP at position 100–106. They were accordingly assigned to chromosome 6D. In total, 16, 0 and 23 epitopes were represented in Galunisertib nmr 8, 6 and 8 genes located
on chromosome 6A, 6B and 6D, respectively. Clearly Zhengmai 004 had full potential Fossariinae to induce the CD syndrome. Based on the deduced amino acid sequences without signal peptides among the 22 cloned genes, as well as all the 95 full-ORF genes derived from three diploid wheat species (46 from T. monococcum, 12 from Ae. speltoides and 37 from Ae. tauschii) in GenBank, a phylogenetic tree was constructed, resulting in clear clustering by genomic origin ( Fig. 3). Most of the sequences derived from T. monococcum and Ae. tauschii, and all the sequences derived from Ae. speltoides, formed separate clusters designated as groups 1, 3 and 2, respectively. Groups 1, 2 and 3 clearly represent the respective α-gliadin genes on the A, B and D genomes, although 11 exceptional genes originating in T. monococcum (protein IDs ACJ76933, ACJ76934, ACJ76935, ACJ76936, ACJ76937 and ACJ76938) and Ae. tauschii (protein IDs ADD17011, ABQ96115, ABQ96118, ABQ96119 and ADM96154), but clustered in group 2, were also detected. Similarly, although most of the 22 genes cloned in this work and located on chromosome 6A, 6B and 6D were clustered respectively in groups 1, 2 and 3, two (Z4A-5 and Z4A-22) exceptional genes were also found.
