Molecular Plant-Microbe Interactions. 13:942-950 Research Interests: Our central focus is on plant cell wall metabolism as an integral part of important events in developmental biology. We study (1) cell wall metabolism in ripening fruits and the relationship of wall changes to fruit softening, (2) the interactions of fruit and other plant organs with pathogens, focusing on pathogen pectin-degrading enzymes and their interaction with plant inhibitors of those enzymes, and (3) the interactions of plants with insects, focusing on the roles of cell wall-digesting enzymes in insect salivary secretions. A common thread running through these studies is the regulatory role played by oligosaccharides generated as plant cell wall pectins are digested by plant, pathogen or insect enzymes. Recently we have added to the research program by adapting what we understand about in planta cell wall disassembly for use in identifying approaches to facilitate the use of lignocellulose as a source of biofuels. Laboratory Personnel: 1401 Plant Reproductive Biology - Carl Greve (in charge), Dario Cantu (PBGG Ph.D. candidate from Italy), Jim Langston (BMB Ph.D. candidate from the US), Zac Chestnut (PBGG student from the US), Lianhai Fu (Postdoc, originally from China), Shengke Tian and Lingli Lu (Ph.D. students from Zhejiang University, China; visiting researchers), Ray Chao and Aleks Milman (Undergraduate Researchers) Teaching Interests:At the undergraduate level, I am interested in teaching introductory plant-related courses and upper division courses in topics related to plant development. I have regularly taught a Freshman Seminar course that is designed to introduce freshmen to UCD's efforts in plant research. At the graduate level in Plant Biology I have a variety of teaching interests. These are generally related to aspects of cell and developmental biology. This includes a course in my program's research focus, Plant Cell Walls Courses Taught: PBI 200B PBGG Core Course (Plant Development, Cell Biology and Metabolism). - Term(s): Winter FRS 1 Freshman Seminar: Research in Plant Biology: Relevance for Students, Society and Scientists - Term(s): Fall,Spring PLS 100B Crop Plant Development - Term(s): Winter PBI 214 The Plant Cell Wall (even years) - Term(s): Winter |
