GmWRKY45 Enhances Tolerance to Phosphate Starvation and Salt Stress, and Changes Fertility in Transgenic Arabidopsis.

ABSTRACT: WRKY protein is a unique transcription factor (TF) and plays an important role in the physiological processes of various stress responses and plant development. In this research, we obtained a WRKY TF gene from soybean by homologous cloning, and named it GmWRKY45. GmWRKY45 is a nuclear protein containing a highly conserved WRKY domain and a C₂H₂ zinc finger structure, and mainly expressed in roots, flowers and pods of soybean. The quantitative reverse transcription-PCR showed that GmWRKY45 was induced by phosphate starvation and salt stress. As compared with the wild type (WT), overexpression of GmWRKY45 increased the adaptability of transgenic Arabidopsis to phosphate starvation, which might be related to the enhancement of lateral
