Abstract
The GRAS gene family is a kind of plant-specific transcription factor reported in many plants. To figure out the function of maize GRAS family under stress, we obtained ZmGRAS319 (AC: NC_024462) gene from maize (Zea mays) root. Sequence analysis showed that the coding sequence (CDS) of ZmGRAS31 was 1422 bp encoding a protein of 473 amino acids with molecular weight of 51,700.38 Da and an isoelectric point of 4.73. Bioinformatics analysis revealed that ZmGRAS31 had a conserved domain unique to the GRAS transcription factor family and poor hydrophilicity, but no transmembrane structure. Transient expression of maize protoplasts indicated that ZmGRAS31 was localized in the nucleus. Real-time quantitative PCR analysis showed that the expression of ZmGRAS31 was up-regulated in maize seedlings under low temperature, dehydration, high salinity and drought conditions. The root length of the ZmGRAS31 overexpression transgenic Arabidopsis plants was longer than that of wide type under different concentrations of NaCl treatments. Therefore, our data suggested that ZmGRAS31 might be involved in abiotic stress response.
