M., “Genetic transformation and expression of transgenic lines of Populus x euramericana with insect-resistance and salt-tolerance genes”, vol. 15, p. -, 2016.

We characterized new transgenic varieties of poplar with multiple insect-resistant and salt stress tolerant genes. Two insect-resistant Bacillus thuringiensis (Bt) genes, Cry1Ac and Cry3A, and a salt-tolerant gene, Betaine aldehyde dehydrogenase (BADH) were inserted into a vector, p209-Cry1Ac-Cry3A-BADH. The clone of Populus x euramericana was transformed by the vector using the Agrobacterium-mediated method.

Drought and salt stresses are the two major factors influencing the yield and quality of crops worldwide. Na+(K+)/H+ antiporters (NHXs) are ubiquitous membrane proteins that play important roles in maintaining the cellular pH and Na+(K+) homeostasis. The model plant Arabidopsis potentially encodes six NHX genes, namely AtNHX1 to 6.

SSR-based association mapping of salt tolerance in cotton (Gossypium hirsutum L.)

Y. L. Zhao, Wang, H. M., Shao, B. X., Chen, W., Guo, Z. J., Gong, H. Y., Sang, X. H., Wang, J. J., Ye, W. W., Zhao, Y. L., Wang, H. M., Shao, B. X., Chen, W., Guo, Z. J., Gong, H. Y., Sang, X. H., Wang, J. J., and Ye, W. W., “SSR-based association mapping of salt tolerance in cotton (Gossypium hirsutum L.)”, vol. 15, p. -, 2016.

The identification of simple sequence repeat (SSR) markers associated with salt tolerance in cotton contributes to molecular assisted selection (MAS), which can improve the efficiency of traditional breeding. In this study, 134 samples of upland cotton cultivars were selected. The seedling emergence rates were tested under 0.3% NaCl stress. A total of 74 SSR markers were used to scan the genomes of these samples.

Enhanced salt tolerance in tomato plants constitutively expressing heat-shock protein in the endoplasmic reticulum

C. Fu, Liu, X. X., Yang, W. W., Zhao, C. M., Liu, J., Fu, C., Liu, X. X., Yang, W. W., Zhao, C. M., and Liu, J., “Enhanced salt tolerance in tomato plants constitutively expressing heat-shock protein in the endoplasmic reticulum”, vol. 15, p. -, 2016.

The accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER) causes ER stress and activates the unfolded protein response (UPR) signaling pathway. The UPR signaling pathway is associated with plant responses to adverse environmental conditions. Thus, changes in the UPR signaling pathway might affect plant abiotic tolerance. Here, the role of ER small heat-shock protein (ER-sHSP) in improving plant resistance to salt stress was explored.
