Plant Genetics and Breeding Laboratory Kenichi MATSUSHIMA Associate Professor Chili pepper Buckwheat Genetic resources Ethnobotany Local traditional variety Molecular genetics Advanced theory and practical methods of plant breeding based on the latest knowledge in genetics and biotechnology will be provided for graduate students by two Professors through seminars and dissertation research for M.S. / Ph.D. degrees with a well-equipped laboratory and field. And also, Research for preservation and reevaluation of local varieties of vegetables and crops are carried to develop agriculture in rural area. The main research materials are chili pepper and buckwheat. International students will be cordially received. Ethnobotanical research on plant resources has been carried out in field explorations of overseas countries as well as in Japan. Collected plant resources such as buckwheat, chili pepper and amaranth including their wild relatives are being investigated in a phylogenetic study and evaluated as breeding materials. A B C D A B C Breeding research using the latest methods of biotechnology is a major research effort. For example, interspecific hybridization using embryo/ovule culture, expression analysis of specific gene and development of DNA markers linked with desired genes for marker assisted selection are being advanced in buckwheat and chili pepper. Bioresource Science Division Left; Interspecific hybrid of chili pepper using embryo culture technique. Right; New variety of chili pepper developed for rural area. Wild edible plant resources collected in the eastern Bhutan. Laboratory of Vegetable and Ornamental Horticulture Yoshikuni KITAMURA Assistant Professor Key words Conductive tissue in floral organ Cut flower Floral organ morphogenesis Functional flavones Our interest is the physiology and ecology of the horticultural plants, and studying them aiming for the application for the horticultural production. Our main subjects are establishment of physiological regulation for the harvesting the lettuce, elucidating the relation between the conductive tissue in floral organs and vase life of the cut flowers, accumulating the functional flavones by regulating the secondary metabolic pathway, archiving continuous flowering in ornamental plants, and stabilization of flower color. Elucidating the underlying mechanism for the long lasting cut flowers. A B C D A B C We are studying the underlying mechanism for the long lasting cut flowers using hydrangea. We are studying the stability of the green flower color using Japanese original green lily cultivar ‘Alp’. Regulation of the expression of the genes for the floral organ morphogenesis aiming for the flower color stabilization. Accumulating apigenin and luteorin in dahlia flower aiming for using dahlia flower as a new edible flower. Bioresource Science Division 17
