Cloning and functional characterization of the HbSYR1 gene encoding a syntaxin-related protein in Tibetan hulless barley (Hordeum vulgare L. var. nudum HK. f.)

Tibetan barley is a staple food for the natives of Qinghai-Tibet Plateau. Drought causes a reduction in barley production. In this study, the full-length cDNA of a gene encoding a syntaxin-associated protein was cloned from the leaves of a drought-resistant variety of barley, “Himalaya 10”; its expression was evaluated during drought stress and rehydrati..

Cloning and characterization of up-regulated HbSINA4 gene induced by drought stress in Tibetan hulless barley

    H.J. Yuan, X.M. Luo, T.S. Nyima, Y.L. Wang, Q.J. Xu and X.Q. Zeng

Hulless barley is an important crop cereal in Tibetan, China. Drought is a major abiotic stress in barley production. In this study, we cloned the drought-related HbSINA4 gene from the variety ‘Himalaya 10’ and analyzed its expression patterns under different drought and rehydration conditions. The cDNA of HbSINA4 was 1052 bp long, incl.. Read More»

Genetic variability in agronomic traits of a germplasm collection of hulless barley

    X.Q. Zeng

Germplasm collections represent an important genetic source for crop improvements. In this study, 220 accessions of hulless barley were collected worldwide and their genetic diversity was investigated. Sixteen agronomic traits, including yield and yield components, grain morphology, leaf size, plant height, and lodging resistance, were assessed under field conditions. All studied traits exhibit..

Genetic relationship between lodging and lodging components in barley (Hordeum vulgare) based on unconditional and conditional quantitative trait locus analyses

    W.Y. Chen, Z.M. Liu, G.B. Deng1, Z.F. Pan, J.J. Liang, X.Q. Zeng, N.M. Tashi, H. Long and M.Q. Yu

Lodging (LD) is a major constraint limiting the yield and forage quality of barley. Detailed analyses of LD component (LDC) traits were conducted using 246 F2 plants generated from a cross between cultivars ZQ320 and 1277. Genetic relationships between LD and LDC were evaluated by unconditional and conditional quantitative trait locus (QTL) mapping with 117 simple s.. Read More»

NJ cluster analysis of the SnRK2, PYR/PYL/RCAR, and ABF genes in Tibetan hulless barley

    H.J. Yuan, Y.L. Wang, Z.X. Wei, Q.J. Xu, X.Q. Zeng, Y.W. Tang and T.S. Nyima

The abscisic acid (ABA) signaling pathway is known as one of the most important signaling pathways in plants and is mediated by multiple regulators. The genes SnRK2, PYR/PYL/RCAR, and ABF are relevant to both ABA-dependent and -independent signaling pathways. To elucidate the profile of these genes from Tibetan hulless barley (Hordeum vulgare L. var. nudum Hook. f.).. Read More»
