Identification and sequence analysis of grain softness protein in selected wheat, rye and triticale

M. A. S. Kharrazi and Bobojonov, V., Identification and sequence analysis of grain softness protein in selected wheat, rye and triticale, vol. 11, pp. 2578-2584, 2012.

Grain softness protein (GSP) is an important protein for overcoming milling and grain defenses in the innate immunity systems of cereals. The objective of this study was to evaluate and understand GSP sequences in selected wheat, rye and triticale. Using sequences for this gene from a sequence database, we performed clustering analysis to compare the sequences obtained from 3 germplasms with other studied sequences for GSP. The maximum difference between the Hirmand GSP genotype in wheat and the database sequences was 23% in EF109396 and EF109399.

Mitotic and meiotic behavior of rye chromosomes in wheat - Psathyrostachys huashanica amphiploid x triticale progeny

Q. Xie, Kang, H., Sparkes, D. L., Tao, S., Fan, X. M., Xu, L., Fan, X., Sha, L., Zhang, H., Wang, Y., Zeng, J., and Zhou, Y., Mitotic and meiotic behavior of rye chromosomes in wheat - Psathyrostachys huashanica amphiploid x triticale progeny, vol. 12, pp. 2537-2548, 2013.

The dynamics of rye chromosomes during mitosis and meiosis was analyzed in a subset comprising 33 F3 lines from the cross of wheat, Psathyrostachys huashanica amphiploid (AABBDDNsNs) and hexaploid triticale (AABBRR), as visualized by genomic in situ hybridization. The results indicated that 31 of the total lines contained 4-14 rye chromosomes. Twenty-eight combinations had more rye chromosomes than the F1 hybrids, suggesting the occurrence of spontaneous quantitative increment. No P.
