Epigenetische Mechanismen der pflanzlichen Reproduktion
PostDoc
Forschungsinteressen
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?
