Purple acid phosphatase (PAPs) is a kind of acid phosphatase, which can effectively hydrolyze organic phosphorus such as anhydrides and phosphates into inorganic phosphorus that can be directly absorbed and utilized by plants under acid conditions. It is one of the important mechanisms for plants to adapt to low phosphorus stress that roots enhance the synthesis and secretion of PAPs, which is also a typical feature of plants with high phosphorus use efficiency. There are universality and diversity of functional characteristics of PAPs in different plant types and genotypes, but the specific function and expression of most PAPs and their coding genes in response to low phosphorus stress still need to be improved. In this paper, the functional structure and protein characteristics of PAPs were analyzed, and the secretion of PAPs in plant roots and the biological function of PAPs coding gene under low phosphorus stress were reviewed, in order to provide reference for further understanding of the functional characteristics of PAPs in response to low phosphorus stress.
