Jian Gao is a researcher in crop genetics and breeding with expertise in radish genomics and functional genomics. His research centers on the genetic regulation of anthocyanin biosynthesis and the molecular mechanisms of plant responses to heavy metal and abiotic stresses. He applies genome-wide analysis, transcriptomics, and bioinformatics to identify key functional genes and regulatory networks. His studies on gene families such as GST and GRAS have provided important insights into stress tolerance and quality trait formation in radish. He has also contributed to microRNA and regulatory gene research related to environmental stress responses in plants. Beyond plant science, his work extends to applied genomics using high-throughput sequencing technologies. His research has been published in leading international journals in plant science and molecular biology. He has played leading and collaborative roles in multiple competitive research projects. His work has resulted in authorized patents and the development of improved radish varieties. He is actively involved in graduate training and interdisciplinary teaching in genomics and bioinformatics.
