摘要
酸性土壤占世界潜耕性土壤的50%,而缺磷(P)和铝(Al)毒是酸性土壤限制植物生长的两大营养逆境因子。有机酸、激素和铁(Fe)稳态在植物响应2种胁迫的信号交互和协同进化中扮演核心作用。系统综述了有机酸分泌、STOP1/ALMT1和STAR1/ALS3多效性调节、激素信号转导和细胞壁相关激酶在调控植物根发育和根构型以改善酸性土壤P有效性和Al耐性的分子生理机制,并对该领域发展前景进行了展望。
Acid soils comprise approximately 50%of potential arable lands worldwide.Phosphorus(P)deficiency and aluminum(Al)toxicity are two major nutritional stress factors limiting plant growth on acid soils.Studies have shown that organic acids(OA),hormones and iron(Fe)homeostasis play a core role in co-evolution and signal crosstalk of plant responses to both stresses.This article systematically reviewed the physiological and molecular mechanisms of OA secretion,pleiotropic regulation of STOP1/ALMT1 and STAR1/ALS3,hormone signal transduction and cell wall-related kinases in regulating plant root development and root architecture to improve P availability and Al resistance on acid soils and also prospected the visions in this field.
