Furthermore, of all nutrients, shortage of phosphorus has the biggest impact on legumes, therefore, lots of studies were carried out for identifying responses of legumes to shortage of phosphorus. They concluded that to maintain improved growth under phosphorus defioiency oonditions plants develop two major mechanisms： （i） Phosphorus acquisition （root morphology, root exudation and phosphorus uptake mechanisms）, （ii） Phosphorus utilization （internal mechanisms associated with better use of absorbed phosphorus at cellular level）. The aim of this brief review is to elucidate root morphological ohanges and rhizophere aoidification to phosphorus deficiency.展开更多

文摘Phosphorus deficiency is a universal problem in most world soils. Furthermore, of all nutrients, shortage of phosphorus has the biggest impact on legumes, therefore, lots of studies were carried out for identifying responses of legumes to shortage of phosphorus.
