Purple acid phosphatases ( PAP )-encoding genes form a complex network that play a critical role in plant phosphate (Pi) homeostasis. Mostly, the functions of PAPs were investigated individually. However, the interactions of most of these genes in response to various concentrations of available Pi remain unknown. In this study, the roles of  AtPAP17  and  AtPAP26  genes, and their relationship within Pi homeostasis context were investigated. Surprisingly,  atpap17  and  atpap26  mutants not only showed no obvious developmental defects, but also produced higher biomass in compare to wild type (WT) plants under normal growth conditions. Comparing gene expression patterns of these mutants with WT plant, we identified a set of genes up-regulated in mutant plants but not in WT. Based on these unexpected results and up-regulation of  AtPAP17  and  AtPAP26  genes by the loss of function of each other, the hypothesis of compensation relationship between these genes in Pi homeostasis was assessed by generating  atpap17/atpap26  double mutants. Observation of developmental defects in  atpap17/atpap26  mutant but not in single mutants indicated a compensation relationship between  AtPAP17  and  AtPAP26  genes in Pi homeostasis network. Taken together, these results demonstrate the activation of  AtPAP17  and  AtPAP26  genes to buffer against the loss of function of each other, and this compensation relationship is vital for Arabidopsis growth and development.
