| Abstract: | NAC transcription factors are known to be involved in regulation of plant responses to drought stress. In this study, the expression of 23 drought-responsive GmNAC genes was assessed in the shoot tissues of DT51 and MTD720, the two soybean varieties with contrasting drought-responsive phenotypes, by real-time quantitative PCR (RT-qPCR) under normal and drought conditions. Results indicated that expression profile of GmNAC genes was genotype-dependent, and six GmNACs (GmNAC019, 043, 062, 085, 095 and 101) had higher transcript levels in the shoots of the drought-tolerant DT51 in comparison with the drought-sensitive MTD720 under drought. Our study suggests a positive correlation between the higher drought tolerance degree of DT51 versus MTD720 and the upregulation of at least these six drought-responsive GmNACs in the shoot tissues. Furthermore, on the basis of our analysis, three genes, GmNAC043, 085 and 101, were identified as promising candidates for development of droughttolerant soybean cultivars by genetic engineering. |
