A Cu/Zn superoxide dismutase from Jatropha curcas enhances salt tolerance of Arabidopsis thaliana

Z. B. Liu, Zhang, W. J., Gong, X. D., Zhang, Q., and Zhou, L. R., A Cu/Zn superoxide dismutase from Jatropha curcas enhances salt tolerance of Arabidopsis thaliana, vol. 14, pp. 2086-2098, 2015.

Superoxide dismutases (SODs) are involved in protecting plants against diverse biotic and abiotic stresses. In the present study, a novel Cu/Zn-SOD gene (JcCu/Zn-SOD) was cloned from Jatropha curcas L. Quantitative reverse transcription-polymerase chain reaction analysis revealed that JcCu/Zn-SOD is constitutively expressed in different tissues of J. curcas and induced under NaCl treatment.

Differential gene expression in drought-tolerant sugarcane roots

J. S. Vantini, Dedemo, G. C., Gimenez, D. F. Jovino, Fonseca, L. F. S., Tezza, R. I. D., Mutton, M. A., Ferro, J. A., and Ferro, M. I. T., Differential gene expression in drought-tolerant sugarcane roots, vol. 14, pp. 7196-7207, 2015.

Drought is one of the most frequent abiotic stresses limiting the productivity and geographical distribution of sugarcane culture. The use of drought-tolerant genotypes is one approach for overcoming the effects of water stress. We conducted a comparative study to identify gene expression profiles under water stress in tolerant sugarcane roots. Two different cultivars, 1 drought tolerant (RB867515) and 1 drought susceptible (SP86-155), were evaluated at 4 sampling time points (1, 3, 5, and 10 days) using the cDNA-amplified fragment length polymorphism technique.
