Research

I am focus on utilizing bacteria to increase plant resistance against pests through altered plant secondary metabolites. Specifically, I am using Pseudomonas syringae to increase the resistance of tomato and chrysanthemum against western flower thrips.

The western flower thrips is one of the most serious greenhouse pests against agriculture and horticultural crops worldwide. It is highly polyphagous with about 200 recorded wild and cultivated hosts. Current control of western flower thrips depends mainly on the use of pesticides. However pesticides application can lead to many other problems. Therefore, other eco-friendly tactics are needed to be developed, among them are increased host plant resistance with elicitors, such as jasmonic acid mimic coronatine (COR).

In my project, I am going to apply COR-producing bacteria Pseudomonas syringae on tomato and chrysanthemum, as models for agri- and horticulture respectively, instead of using the chemical COR itself to achieve a long period effectiveness. I will establish a standard method to inoculate plants with these bacteria. Thereafter test the plant resistance against thrips with bioassay and study the underlying genetic, metabolomic and mechanical mechanisms in response to bacterial inoculation. Ultimately, reliable approaches of controlling thrips will be provided under Integrated Pest Management (IPM) system.
