He graduated from Prof. Chen has been engaged in plant science research for a long time, and has made outstanding achievements in plant resources, secondary metabolism, cotton biology, and innovation of plant biotechnology against insect pests. He has made outstanding contributions to botany research and the development of Shanghai Chenshan Botanical Garden. The main achievements are reflected in four aspects. 1. Collection of medicinal plants and investigation of terpenoid biosynthesis During his doctoral studies and work at Nanjing University, Xiao-Ya Chen conducted systematic research on plants of Angelica and Ferula, family Umbelliferae, and was one of the earliest scholars in China to do plant chemotaxonomy research. Since 2005, appointed by the Chinese Academy of Sciences, he joined the team of designing, planning and construction of Shanghai Chenshan Botanical Garden. He has made important contributions to the establishment of Chenshan Plant Science Research Center of the Chinese Academy of Sciences, and the development of science research programs. At the same time, he led a team dedicated to the collection, conservation, and research of medicinal plant resources in the Labiatae family, collecting over 300 species of Labiatae plants, and building the largest core germplasm resource bank, as well as the conservation and breeding nursery of Salvia plants from China and abroad. They have made important progresses in genomics and metabolomics research of medicinal plants, such as Salvia miltiorrhiza, S. officinalis, Artemisia annua, patchouli and Scutellaria baicalensis. Their researches have revealed correlation between the evolution of tanshinone synthesis pathway and the formation of storage roots. Breakthrough progress has been made in the elucidation and metabolic engineering of plant coenzyme Q biosynthetic pathway. 2. Elucidation of gossypol biosynthetic pathway Cotton plants in the genus Gossypium of Malvaceae family synthesize sesquiterpenoid compounds, such as gossypol, to resist pathogen infection and insect feeding. The high content of gossypol in cotton seeds, however, limits their application as vegetable oil and feeding stuff. Prof. Chen's group has devoted to the studies of gossypol biosynthesis for more than 30 years, and has fully elucidated the biosynthetic pathway of from farnesyl diphosphate (FDP) to gossypol. They cloned and identified the FDP synthase (FPS) that provides sesquiterpene precursors, the (+)-delta-cadinene synthase (CDN) that forms the basic backbone of gossypol, the cytochrome P450 monooxygenase (CYP706B1, CYP82D113, CYP71BE79, CYP736A196), the dioxygenase 2-ODD-1, the alcohol dehydrogenase DH1, and the aromatase SPG that modify and decorate the skeleton to form functional groups, and finally the dirigent proteins GhDIR5 and GhDIR6 that impart the hemigossypol oxidative coupling into (−)- and (+)-gossypol, respectively. To reduce cotton seed toxicity, they disrupted GhDIR5 gene by genome editing, resulting in effective elimination of (−)-gossypol from cottonseed without affecting other phytoalexins, including (+)-gossypol, that provide pest resistance, thereby improving the utilization of cottonseed products. The elucidation of gossypol biosynthetic pathway is an important progress in the field of plant secondary metabolism research, and of great importance in improving cotton quality. 3. Dissect the regulatory mechanism of cotton fiber elongation In the research of cotton fiber development, Chen's group identified that the cotton HD-ZIP transcription factor HOX3 is a master regulator of cotton fiber elongation. HOX3 interacts with DELLA protein to transduce the gibberellin signal into fiber cell growth, and with the miR319-targeted TCP4 to coordinate cotton fiber elongation and secondary wall thickening. They also characterized genes involved in cotton fiber cell elongation (PRE1) and cell wall loosening (RDL1). All these findings are of great importance for the formation of cotton fiber quality traits. In addition, they were also involved in sequencing of upland cotton and island cotton genomes. 4. Develop RNAi technology for plant protection Secondary metabolites play an important role in plant-insect interactions and coevolution. During analyzing the detoxification mechanism of cotton bollworm towards gossypol, they developed the plant-mediated insect RNAi by expressing double stranded RNA of insect gene in plants, so that the growth of insect feeders are inhibited. This achievement is a milestone breakthrough in the development advanced biotechnology for plant protection against pests and pathogens, and has been widely used in many institutions to develop crops with enhanced disease or pest resistance. In addition, their research revealed the “double-edged sword” role of plant secondary metabolites in plant-insect interactions, and the dynamic changes of plant immunity or defense reactions during plant aging. Besides, they also engineered plant to secrete laccase from root to transform phenolic pollutants in the soil, thus providing new strategies for soil remediation. Prof. Chen has published about 200 papers in scientific journals, including Nature Biotechnology, Nature Chemical Biology, Nature Plants, PNAS, Plant Cell, Molecular Plant, and has been listed as Highly Cited Researcher by Clarivate multiple times. He has more than 30 authorized invention patents. To date more than 80 postdocs, PhD and Master Degree graduate students have worked or studies in his laboratory. He has edited or jointly edited books, including “Plant Physiology and Molecular Biology” (a textbook for graduate schools), “On Hundred Thousand Whys - Plants (sixth edition)”. He has contributed to plant science research, education, popularization, and plant conservation in China. |
