摘要/Abstract

摘要：

磷是植物必需的重要营养元素之一,是生物大分子的重要组成部分,在植物生命过程中发挥着不可或缺的作用。维持体内磷稳态对于植物的生长发育和环境应答至关重要。多种信号分子参与调控植物对磷的吸收和转运。植物维持磷稳态主要包括土壤磷的活化、磷的吸收、转运、存储和再利用等过程,涉及磷胁迫响应、转录因子调节、miRNA调节、菌根共生、细胞器间转移等磷调节机制。未来的磷营养机制研究需要跨学科知识的融合,由模式植物研究转向栽培作物。全面总结了植物细胞磷吸收和转运的核心分子及其作用机制的研究进展,旨在为作物品种改良和遗传育种提供重要借鉴。

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
