Research Description:

His laboratory is interested in understanding the molecular mechanisms and gene regulatory networks through which plant steroid hormone, Brassinosteroid (BRs), regulate plant growth and stress responses. His Lab uses a combination of genetics, genomics, computational modeling and predicative phenomics approaches and model plant Arabidopsis thaliana in their research. The long-term goal is to apply the knowledge generated from model systems to improve crop production under adverse climate conditions. There are several lines of research:

1. Investigate the Mechanisms and Networks for BR Regulated Plant Growth and Stress Responses: his lab has previously established that BRs function through BES1/BZR1 family transcriptional factors to mediate BR responses. They have identified many BES1 interacting proteins and target genes, based on which they have established BR Gene Regulatory Networks (GRNs) by computational modeling, in collaboration with M. Aluru and S. Aluru at Georgia Tech. they are currently investigating the functions of genes in the BR regulatory networks and the mechanisms of actions in plant growth and stress responses.

2. Use Predicative Phenomics to Study BR Gene Regulatory Networks (GRNs): In collaboration with several groups including L. Tang, P. Schnable, S. Sarkar, L. Dong and S. Howell, they are developing new phenotyping tools that can be used to study the functions of a large number of genes in GRNs. These include developing a platform to phenotype plant growth under drought conditions and using the platform to study the functions of hundreds of genes identified by computational modeling and quantitative genetics. The goal is to establish relationship between GRNs generated from predicative modeling and plant performance under various stress conditions.

3. Define the Functions and Signaling Pathways for the HERCULES Receptor-Like Kinases (HERKs): They have discovered that several CrRLK1L family receptor kinase genes, including HERK1, THE1 (THESEUS 1) and FER (FERONIA), are regulated by BRs and involved in plant growth and immunity.  They are using multidisciplinary approaches to study signaling transduction pathways for these receptor kinases. Their collaborators on this project include Y. Lee, E. Yu laboratories.
