十字花科植物是世界上种植最广泛、最重要的作物之一。磷（P）是所有植物生长的关键矿物元素，主要以无机磷酸盐的形式提供，这是一种日益减少的资源，可能成为全球农业中日益重要的因素。为了开发能从土壤中提取磷、更有效地利用磷、需要更少的磷或从土壤有机磷库等其他来源获得更多磷的作物，需要详细了解影响植物和相关土壤中磷代谢和循环的因素。本文综述了目前的理解状态的根性状，根沉积和根际社区的相互作用，因为它适用于磷的溶解和收购，特别是参考芸苔属物种。被认为是物理根特性，有机酸（特别是苹果酸和柠檬酸）和磷酸酶的分泌和潜在的控制机制，这些反应的P缺乏检查。讨论了根际沉积物对根际微生物群落发育的影响，并考虑了该群落对缺磷反应的具体特征;特别是磷酸酶、植酸酶和膦酸酯水解酶的产生。最后讨论了提高芸苔属作物磷素利用率的途径。
Brassicas are among the most widely grown and important crops worldwide. Phosphorus (P) is a key mineral element in the growth of all plants and is largely supplied as inorganic rock-phosphate, a dwindling resource, which is likely to be an increasingly significant factor in global agriculture. In order to develop crops which can abstract P from the soil, utilize it more efficiently, require less of it or obtain more from other sources such as soil organic P reservoirs, a detailed understanding the factors that influence P metabolism and cycling in plants and associated soil is required. This review focuses on the current state of understanding of root traits, rhizodeposition and rhizosphere community interaction as it applies to P solubilization and acquisition, with particular reference to Brassica species. Physical root characteristics, exudation of organic acids (particularly malate and citrate) and phosphatase enzymes are considered and the potential mechanisms of control of these responses to P deficiency examined. The influence of rhizodeposits on the development of the rhizosphere microbial community is discussed and the specific features of this community in response to P deficiency are considered; specifically production of phosphatases, phytases and phosphonate hydrolases. Finally various potential approaches for improving overall P use efficiency in Brassica production are discussed.
