摘要

Phosphorus (P) is one of the most limiting plant nutrients in many agro-eco-systems. Phosphate ( Pi) deficiency is particularly acute in acid soils spread around the world. Plants in general deploy a range of adaptive strategies to obtain phosphate from both inorganic and organic complexes. The response of plants to Pi deficiency is quite complex and well orchestrated at the level of transcription. Expression of large number of genes, including transcription factors, is altered during adaptation of plants to Pi starvation. The number of characterized transcription factors associated with Pi starvation responses is increasing. Alterations in the expression of transcription factors have been shown to affect many of the Pi starvation adaptive traits including Pi uptake, phosphatase production, root morphology, plant pigmentation and hormone responses. This review highlights the role of transcription factors in the regulation of a host of Pi starvation responses in plants.
