Dr. Hua Jiang

My research focuses on understanding the regulation of plant germline development under both normal and stressed conditions. Ultimately, my aim is to enhance reproductive tolerance and harness environmental sensitivity for crop breeding.

Key Questions:

What mechanisms govern the epigenetic basis of plant fertility?
How are ploidy reduction processes controlled during germline development?
What mechanisms support thermotolerant germline development?
