B. Diversity of soil nematodes and its ecological function

C. Biological characteristics of Entomopathogenic nematode (EPN) and biological control of crop pests

II. Research Interests and objectives

A. Plant-parasitic nematodes (PPN) cause substantial agricultural loss of more than $150 billion annually throughout the world. Root-knot nematodes (RKN) and cyst nematodes are the two most damaging groups PPN and are widely distributed worldwide on many crops. Our research focuses on the two nematodes to study the interaction between nematodes and plants in the molecular and genetic level. Research includes a defined combination of themes selected among the areas of nematode–plant interaction, host-perception genes in nematodes, host defense genes in plants, resistance genes in plants, avirulence genes in nematodes, plant genetic resistance, nematode identification, nematode-disease complex infection, IPM, and biotechnology. Functional genomics study on soybean cyst nematodes is one of my important research areas, which will allow us to address genome-wide disease responses. Research discovery in this area will result in a better understanding of biology of complex interactions between plants and nematodes and correspondingly new targets for control strategies will be explored.

B. Soil nematodes are part of a complex soil ecosystem, and they are diverse and widely distribute over the world. Soil nematodes play important role in soil food web, and directly or indirectly involve in nutrition cycle, energy flow and other biological processes, etc. Not only can soil nematode diversity indicate the soil biological diversity and disturbance of soil environment, but soil nematode community structure can reflect the character of soil food web and function of soil ecosystems. If the function of soil nematodes and condition of soil ecosystems are combined, the influence of outer disturbance or environment change on soil biological diversity, soil food web and function of soil ecosystems will be further revealed.

C. Entomopathogenic nematodes (EPNs), not same as plant-parasitic nematodes, is beneficial nematodes to human and environment. EPNs as alternatives to chemical pesticiedes are used as bio-control agent to host insect. Together with symbiotic bacteria, EPN can kill insect pests. The complex of interaction among EPN, symbiotic bacteria, host insect, host-habitat plants and/or soil environment affects biological control efficiency. Therefore, our study focuses on how and why the interaction of EPN-host habitat plant, EPN-host insect, symbiotic bacteria-insect, and soil environment-EPN attraction/repulsion or EPN infection affect control efficiency. Meanwhile, we are trying to utilize EPN to control PPN. The ultimate aim is to reduce or eliminate toxic chemical control and to increase EPN control in order to protect environment and food safety.
