英文摘要: SpERF1 acts as a positive regulator, contributing to drought stress tolerance in A. thaliana through activating DRE/CRT elements in the promoters of abiotic stress-responsive genes.
Stipa purpurea is an endemic perennial grass species in alpine arid and semi-arid meadows on the Qinghai-Xizang Plateau, which is highly tolerant against drought and cold. ERF transcription factors are known to regulate gene expression under abiotic and biotic treatments. Herein, we isolated a full-length ERF gene CDS from S. purpurea named SpERF1, which was induced by drought, cold, and jasmonic acid stresses. Subcellular localization revealed that SpERF1 is a nuclear protein, consistent with its roles as a transcription factor. Overexpression of SpERF1 enhanced drought tolerance of transgenic Arabidopsis thaliana via the activation of DRE/CRT elements in the promoters of abiotic stress-responsive genes. Furthermore, increased accumulation of proline indicated that SpERF1 might be involved in proline synthesis in the transgenic lines, allowing them to have a better buffering capacity and membrane protection under drought stress. This study indicated that SpERF1 might be an attractive target in the genetic engineering for improving stress tolerance in other crops. Moreover, SpERF1 protein function analysis increased our understanding of S. purpurea's ability to adapt to the adverse conditions of the Qinghai-Xizang Plateau.
