Abiotic stress responses in shoot apical meristem
STM signaling networks
|
I have developed integrated transcriptional networks on meristem development and stress signaling pathways in Arabidopsis thaliana. However, it is important to understand how genotype and phenotype correlate for meristem development in accordance to the environmental cues. My lab will combine genomic, genetics, and systems biology approaches to link meristem and stress-associated traits to the gene regulatory networks that control them.

Postharvest senescence in vegetables and fruits
Postharvest senescence in broccoli (Brassica oleracea)
|
The cultivated Brassica species, which are the group of crops most closely related to Arabidopsis. Previous comparative research between Brassica oleracea and Arabidopsis thaliana genome identified numerous one-to-one segmental relationships and genome duplications. However, little is known about the molecular mechanism of postharvest senescence in broccoli. My lab will focus on identifying genes that are involved in postharvest senescence in Brassica oleracea and the other Brassica species . |
Potato tuber meristem and sprout development
|
The meristem for potato tubers (Solanum tuberosum) serve as a excellent system to study meristem development in response to a changing environment because their meristems are large in size and have continued transcriptional activity despite dormancy. The duration of potato tuber dormancy and their sprouting time have significant economic importance and are under environmental, and physiological control.

Cell wall changes and postharvest softening in small fruits
|
|
We are interested in understanding the molecular mechanisms of cell wall changes during fruit ripening and how cell wall breakdown causes postharvest fruit softening in blueberry
