Major quality trait analysis and QTL detection in hexaploid wheat in humid rain-fed agriculture

H. M. Li, Tang, Z. X., Zhang, H. Q., Yan, B. J., and Ren, Z. L., Major quality trait analysis and QTL detection in hexaploid wheat in humid rain-fed agriculture, vol. 12, pp. 1740-1751, 2013.

Humid rain-fed agriculture is a special environment for wheat (Triticum aestivum) culture that tends to negatively affect wheat yield and quality. To identify quality characters of wheat in a humid environment, we conducted quality analysis and quantitative trait loci (QTL) detection in a recombinant inbred line whose parent had a high level of quality for several years. We found that high-quality wheat had less gluten content and lower protein content. Apparently, wheat quality and associated quantity traits were in a dynamic state of equilibrium.

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.

Cloning and characterization of thioredoxin h in the three-pistil line of common wheat

Z. J. Yang, Peng, Z. S., Wu, K., and Wei, S. H., Cloning and characterization of thioredoxin h in the three-pistil line of common wheat, vol. 12, pp. 2688-2701, 2013.

Thioredoxin h (Trxh) is a ubiquitous protein that reduces disulfides in target proteins, and is itself reduced by NADPH-thioredoxin reductase. In the current study, the complementary DNA sequence and the genomic sequence of the three-pistil (TP) line of common wheat (Triticum aestivum L.) were obtained from spikes through reverse transcription-polymerase chain reaction (RT-PCR) and touchdown-PCR. Sequence alignment of amino acids of TPTrxh then allowed for predictions of its physicochemical properties, secondary structures, tertiary structures, and functional domains.
