Drought-tolerant rice germplasm developed from an Oryza officinalis transformation-competent artificial chromosome clone

R. Liu, Zhang, H. H., Chen, Z. X., Shahid, M. Q., Fu, X. L., and Liu, X. D., Drought-tolerant rice germplasm developed from an Oryza officinalis transformation-competent artificial chromosome clone, vol. 14, pp. 13667-13678, 2015.

Oryza officinalis has proven to be a natural gene reservoir for the improvement of domesticated rice as it carries many desirable traits; however, the transfer of elite genes to cultivated rice by conventional hybridization has been a challenge for rice breeders. In this study, the conserved sequence of plant stress-related NAC transcription factors was selected as a probe to screen the O.

Physiological evaluation of the responses of Larix olgensis families to drought stress and proteomic analysis of the superior family

L. Zhang, Zhang, H. G., and Pang, Q. Y., Physiological evaluation of the responses of Larix olgensis families to drought stress and proteomic analysis of the superior family, vol. 14, pp. 15577-15586, 2015.

The conifer Larix olgensis has been analyzed to delineate physiological and proteomic changes that occur under drought stress. Studies of the deleterious effects of drought in the larch families have mainly focused on photosynthesis. In the present study, when the intensity of drought was increased, plant height was inhibited as both POD and MDA levels increased, which indicates oxidative stress.

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

H. J. Yuan, Luo, X. M., Nyima, T. S., Wang, Y. L., Xu, Q. J., and Zeng, X. Q., Cloning and characterization of up-regulated HbSINA4 gene induced by drought stress in Tibetan hulless barley, vol. 14. pp. 15312-15319, 2015.

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, including an open reading frame of 771 bp that encoded a protein of 256 amino acids. The molecular weight of HbSINA4 protein was predicted to be 29.53 kDa and the theoretical pI was 8.32.

Cloning and stress response analysis of the PeDREB2A and PeDREB1A genes in moso bamboo (Phyllostachys edulis)

H. L. Wu, Li, L., Cheng, Z. C., Ge, W., Gao, J., and Li, X. P., Cloning and stress response analysis of the PeDREB2A and PeDREB1A genes in moso bamboo (Phyllostachys edulis), vol. 14, pp. 10206-10223, 2015.

Moso bamboo is a large woody bamboo with the highest ecological, economic, and cultural value among all bamboos in Asia. However, environmental stress influences its growth and development and limits its geographic distribution. Therefore, improving its resistance to environmental stress is extremely important. Dehydration responsive element binding (DREB) transcription factors perform an important role in the regulation of stress-related genes, enhancing the resistance of plants to abiotic stress.
