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 up-regulation 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 drought-tolerant soybean cultivars by genetic engineering.
