Functional analysis of <i>ZmPHR1</i> and <i>ZmPHR2</i> under low-phosphate stress in maize.

ABSTRACT: The PHOSPHATE STARVATION RESPONSE REGULATOR (PHR) plays a crucial regulatory role in plants during the process of responding to phosphate starvation. In this study, we combined reverse genetics and biotechnology to investigate the function of ZmPHR1 and ZmPHR2, including proteins containing the Myb_DNA_banding and Myb_CC-LHEQLE structural domains, in maize seedlings. Phylogenetic analysis revealed that ZmPHR1 and ZmPHR2 have high homology with AtPHR1 and OsPHR2, and share the characteristic features of nuclear localisation and transcriptional self-activation. Real-time quantitative PCR analysis showed that low phosphate (Pi) stress significantly induced the expression of ZmPHR1 and ZmPHR2 in maize seedling stage, and candidate gene as
