    Resume：

    Sun Yucheng, Ph.D, Professor, Principal investigator of “Insect ecological adaptation“ research group, Institute of Zoology, Chinese Academy of Sciences. He received bachelor's degree from Nanchang University in 2003, and got Ph.D in Ecology from Institute of Zoology CAS in 2009. Since July 2009, he has been working in State Key Laboratory of Integrated Management of Pest Insects and Rodents, Institute of Zoology CAS. His group firstly discovered a salivary elicitor cathepsin B3 secreted by green peach aphid that could be recognized by plant immune system, and triggered a Raf-dependent phloem-located defense. It also revealed that TYLCV caused a caspase-dependent apoptotic neurodegeneration in the brain of viruliferous whitefly by inducing an inflammatory signaling cascade of innate immunity. The sensory defects caused by neurodegeneration removed the steady preference of whitefly for virus-infected plants, thereby enhancing virus to enter uninfected hosts, and eventually benefited TYLCV spread among the plant community. Furthermore, a phosphatidylethanolamine binding protein PEBP4 served as a master regulator of apoptosis and autophagy was identified in virus-vector insects for the first time. Coordination of two forms of programmed cell death had optimized virus load and vector fitness, enabling virus-vector coexistence. It improved the immune tolerance of whitefly to arbovirus, and laid the immune basis for the high-efficient virus transmission. Overall, these studies analyzed the key targets and their molecular functions of feeding damage and virus transmission from aspects of behavioral, neural and immune regulation, and provided effective, practical and operative targets for the development of accurate control technology of piercing-sucking insects based on behavioral and immune manipulation. He has published over sixty peer-reviewed SCI papers including PNAS, Nature Communications, Current Biology, eLife, Global Change Biology, New Phytologsit, etc., and participated in editing 6 academic monographs.
    Research Interest：

    My interests primarily focused on feeding behavior regulation of phloem feeding insects, the molecular basis for plant resistance against phloem feeders, the manipulation of arbovirus on immune tolerance of vector insect, and plasticity of aphid wing morph associated with environmental adaptability. Aphids and whiteflies, and their transmitted plant viruses are used to determine: (1) The biochemical and molecular basis of aphid salivary proteins in regulating the plant immunity. (2) The regulatory mechanism of salivary protein secreted by vector insect in facilitating the co-infection of virus and its vector. (3) Immune regulation and balancing homeostasis with vector insects achieved by the arbovirus. (4) Plasticity in aphid wing and ecological adaptation function of endosymbiotic bacteria in aphids.
