A key goal of crop improvement is to engineer/breed plants that rapidly respond and adapt to a changing environment. Our group studies translational control and peptide signaling, two rapid regulatory mechanisms involved in plant growth and environmental responses. We exploit genome-wide approaches to monitor mRNA translation and discover novel peptides simultaneously. Then, we use a combination of molecular biology, genetics, biochemistry and bioinformatics analysis to dissect the regulatory mechanisms. In particular, we focus on gene expression regulation controlled by abiotic stress and stress hormone, abscisic acid (ABA). Our long-term goal is to leverage the novel regulatory mechanisms to promote plant resilience to the environment.
