Brief biography: In 2014, I joined the Lab of Prof. Lei Shi at Huazhong Agricultural University to pursue my Ph.D. study. During Ph.D. period, my research mainly focused on the regulation mechanism of boron efficient absorption in Brassica napus, and I received my Ph.D. degree in plant nutrition in Dec. 2020. Later, I joined the Lab of Prof. Lin Liu at Shenzhen University as a postdoctoral fellow to investigate the regulatory mechanisms of plant microRNAs. The maize transcription factor INDETERMINATE1 (ID1) was first reported to participate in the regulation of maize flowering. In this study, we further revealed that ID1 could modulate the transcription of ZmmiR399 family genes as a negative regulator, thus alleviating the targeted cleavage of ZmPHO2 at mRNA level and contributing to the maintenance of phosphate homeostasis in maize. Our study establishes a regulatory connection between Pi-deprivation sensing by the miR399-ZmPHO2 regulatory module and plant developmental regulation by ID1 in maize.
