Z. T. Ding, Shen, J. Z., Pan, L. L., Wang, Y. U., Li, Y. S., Wang, Y., Sun, H. W., Ding, Z. T., Shen, J. Z., Pan, L. L., Wang, Y. U., Li, Y. S., Wang, Y., and Sun, H. W., CsSAD: a fatty acid desaturase gene involved in abiotic resistance in Camellia sinensis (L.), vol. 15, p. -, 2016.

Tea (Camellia sinensis L.) is a thermophilic evergreen woody plant that has poor cold tolerance. The SAD gene plays a key role in regulating fatty acid synthesis and membrane lipid fluidity in response to temperature change. In this study, full-length SAD cDNA was cloned from tea leaves using rapid amplification of cDNA ends and polymerase chain reaction (PCR)-based methods. Sequence analysis demonstrated that CsSAD had a high similarity to other corresponding cDNAs.

Overexpression of EsMcsu1 from the halophytic plant Eutrema salsugineum promotes abscisic acid biosynthesis and increases drought resistance in alfalfa (Medicago sativa L.)

C. Zhou, Ma, Z. Y., Zhu, L., Guo, J. S., Zhu, J., and Wang, J. F., Overexpression of EsMcsu1 from the halophytic plant Eutrema salsugineum promotes abscisic acid biosynthesis and increases drought resistance in alfalfa (Medicago sativa L.), vol. 14, pp. 17204-17218, 2015.

The stress phytohormone abscisic acid (ABA) plays pivotal roles in plants’ adaptive responses to adverse environments. Molybdenum cofactor sulfurases influence aldehyde oxidase activity and ABA biosynthesis. In this study, we isolated a novel EsMcsu1 gene encoding a molybdenum cofactor sulfurase from Eutrema salsugineum. EsMcus1 transcriptional patterns varied between organs, and its expression was significantly upregulated by abiotic stress or ABA treatment.
