XU lab focus on epigenetic regulation of plant reproductive development and transgenerational inheritance in Arabidopsis, rice or orchid. Our research will combine epigenome, transcriptome, forward (mutant screening) and reverse genetics to understand how floral organ identity genes coordinate epigenetic regulators to control cell identity or function in Arabidopsis and orchid; how transgenerational inheritance traits passed to next generations.  Thus, NGS, genetics, biochemistry, molecular and cellular biology assays would be conducted.
