摘　　要：植物缺磷已经成为世界性的难题,越来越多的研究表明,转录调控是植物耐低磷调控的的重要环节,因此,有关植物低磷诱导转录因子转录机制的研究已成为国内外研究的热点。综述了与植物磷胁迫相关的转录因子PHR1,PHO1,WRKY6等调控磷酸饥饿的方式及其在植物生长发育、根系形态变化和激素信号等方面的功能,并对其研究前景进行了展望。Phosphorus deficiency in the plant is a worldwide problem and more and more evidences indicate that transcriptional regulation is one of the key processes for phosphorus deficiency regulation and the research on the plant transcription mechanism of transcription factors under low-phosphate condition has become a hot issue. In this paper, transcription factors involved in phosphorus stress response were reviewed. The regulation of these factors like PHR1, PHO1 and WRKY6 on plant growth, root architecture, hormone signal transduction were also summarized and a prospect of the transcription factors research was also stated in the review.
