摘要： 挖掘利用植物自身的磷高效营养遗传资源是农业可持续发展的关键。磷高效营养性状涉及根形态、根分泌物、膜与体内磷转运以及菌根等许多方面，表现为数量遗传性状及受多基因控制。近年来，许多高亲和磷转运子基因已被克隆, 磷向地上部转运和磷吸收负反馈调节的控制基因也被发现, 对于根系分泌有机酸和酸性磷酸酶的基因的控制也有了一定的了解, 但目前对于根毛、排根、根构型以及菌根的营养学意义性状的分子生物学研究进展缓慢。
Abstract: Exploration and utilization of the genetic resources of high efficient phosphorus (P) nutrition in plants are the key to sustainable agricultural development. High efficiency of P nutrition
in plants is closely related to root morphology, root exudates, P transport across plasmalemma, phosphorus translocation and symbiosis with microorganisms. These nutritional properties are genetically
controlled by multi-genes and characterized by quantitative trait loci. In past years, many genes encoding high-affinity P transporters have been cloned; the genes regulating root-to-shoot P translocation and down-regulating P absorption have been identified. The genetic regulation of root exudation of organic acids and acid phosphatases has been moderately understood. Bacterial citric synthase has been successfully introduced into and overexpressed in plant cells. However, few advances have been made in the molecular biology of root hair, cluster roots, root architecture and mycorrhiza in relation to high efficient P nutrition.
