Research Interests
The Chen lab initially studied how the identities of floral organs are specified and uncovered the functions of a number of RNA-binding proteins as floral homeotic genes that specify the identities of floral organs. The studies led to the discovery that some of the proteins act in the metabolism or function of microRNAs. The lab then switched research focus and investigated how microRNAs are made, degraded, and who they regulate target genes.
At present, the lab focuses on three main areas of investigation. One is to study how microRNAs move from cell to cell or systemically in plants and how mobile RNAs serve as intercellular signals that coordinate the growth of plant organs in response to warm temperature. The second is to elucidate the mechanisms underlying the deposition, removal and molecular functions of non-canonical RNA caps such as NAD, FAD, and dpCoA caps. The third is to investigate the development of plastids with a focus on understanding gene expression and RNA modifications in plastids.
