RESEARCH
Pattern triggered immunity in horticultural crops
- We use comparative genomics to survey the pattern-recognition receptor (PRRs) repertoire of Chinese cabbage.
- We clone the homologs of known PRRs and test their functionality in Arabidopsis prr mutants.
- We assay the Chinese cabbage physiological responses to treatment with known pathogen-derived molecules.
Pathogen effector impact on plant physiology
- We selected a subset of Ralstonia solanacearum effectors that carry a putative Nuclear Localization Signal.
- We clone the selected effectors into binary vector for heterologous expression in tobacco and Arabidopsis.
- We survey the impact of effector expression on the plant immune system and the root development.
New R genes in horticultural crops
- We use comparative genomics to identify putative avirulent effectors from Korean strains of Ralstonia solanacearum in bacterial wilt resistant Solanaceae.
- We clone individual avirulent effector candidates into different vector to find a suitable delivery method in Solanaceae leaves.
- We test hypersensitive response following effector delivery in various segregating populations.
- We develop molecular markers linked with bacterial wilt resistance for accelerated breeding of resistant cultivars.
