Research interests

In our lab, we are trying to understand ABA signaling and how plants respond to environmental stress. ABA is a key hormone which not only controlling plant growth and development, but also functions as one of the most important signal for aboitic stress response. In ABA signaling pathway, a number of transcription factors had been identified and characterized. In our previous study, we had found Arabidopsis Ring finger protein RHA2a and RHA2b play key role in ABA-mediated control of seed germination, early seedling development and drought tolerance. Genetic analysis showed that RHA2a and RHA2b act independently with well known transcription factor ABI3, ABI4 and ABI5. RHA2a and RHA2b were functional E3 ubiquitin ligase, and their conserved RING domain was critical for the biological function. We are using a combination of biochemical, genetic, molecular and functional genomic approaches to understand the following goals using Arabidopsis and Rice as model systems:

1. Action mechanism of RHA2a and RHA2b in ABA signaling pathway.

2. Understand the function of RHA2a-like Ring finger protein in ABA signaling and plant stress response
