Regulation Mechanism of Phosphate Homeostasis in Plants

doi:10.13560/j.cnki.biotech.bull.1985.2021-0472

Abstract

Abstract:

Phosphorus is one of the essential plant macronutrient,which is an important component of life macromolecules,and plays an indispensable role in the process of plant life cycle. Maintaining phosphate homeostasis is critical for plant growth and environmental response. Phosphate homeostasis uptake and transport in plants involves multiple signaling molecules. The process of plant maintaining phosphate homeostasis mainly includes the activation of soil phosphate homeostasis,the uptake and transportation of phosphate homeostasis,the allocation and remobilization of phosphate in plants. It involves phosphate homeostasis mechanisms such as response to low phosphate homeostasis stress,transcription factor regulation,miRNA regulation,mycorrhizal symbiosis,inter organelle transfer regulation and so on. The research of phosphate homeostasis nutrition mechanism in the future needs the integration of interdisciplinary knowledge,from model plant research to commercial crops. In this paper, we summarized the latest research progress on the core molecules and their mechanisms of uptake and transport of phosphate in plant cells,aiming to provide an important reference for crop engineering and breeding strategies.

Key words: phosphate homeostasis, low phosphate homeostasis stress, mycorrhizal fungi, transcription factor, miRNA
