Abstract:MAX4 gene has been shown to be involved in the regulation of shoot branching in Arabidopsis (Arabidopsis thaliana). However, little is known about the role of MAX4 gene in low inorganic phosphate (Pi) stress response in Arabidopsis. Here we showed that MAX4 gene is involved in the regulation of low Pi stress response in Arabidopsis. MAX4 gene was repressed by low Pi stress, and the max4 mutants showed lower anthocyanin content and longer primary root length. In addition, max4 mutant plants also displayed altered root architecture such as increased root-to-shoot ratio, lower lateral root number and root hair density compared with wild-type plants under low Pi stress. Higher total Pi contents were detected in shoots and roots of max4 plants than those of wild-type plants when subjected to low Pi stress, which was associated, at least in part, with increase in expression of WRKY75 as well as AtPT1 and AtPT2 genes encoding high-affinity Pi transporters. Taken together, all these results suggest that MAX4 gene mediates low Pi stress response, at least in part, by regulating the expression of WRKY75 as well as AtPT1 and AtPT2 genes.
