1. Molecular mechanisms of plant responses to abiotic stress (extreme temperatures and drought stress)
Adverse effects caused by abiotic stresses including drought, salinity, cold and heat stress result in huge yield loss of crops worldwide. To survive in a fixed environment, plants have to adjust their metabolisms and developmental programs to adapt to environmental stress or acclimate to the transitory stress. The ultimate goal of this project is to understand the Molecular mechanisms of plant responses to abiotic stress. We are using genetic, biochemical, genomic, and physiological approaches to try to elucidate the molecular mechanisms of plant stress responses with Arabidopsis thaliana and apple trees as plant materials.
2. Molecular marker-assisted apple breeding at whole-genome level with stress- resistant traits.
Another focus of my research is on the area of plant breeding. Currently, we are investigating the genetics of abiotic stresses in apple trees, with emphasis on the use of molecular markers at whole-genome level. The goal of this project is to obtain new apple cultivars with abiotic stress-resistant traits.
