Summary of main research topics

Molecular genetics of barley: morphology, seed quality, and disease resistance
Barley, regarded as the fourth most important cereal in the world, is used for food, brewing of beer, and animal feed. Different uses require particular quality standards. Our current research specifically examines molecular characterization of barley genes controlling plant morphology, healthy seed constituents, and viral disease resistance. Such basic research is expected to facilitate the breeding of new cultivars. Despite its huge genome size (5 Gbp) with limited genome sequence information, we are identifying many key genes of barley. Our interests also extend to the transfer of outcomes from barley to hexaploid wheat. 

Studies on plant systematics and conservation; Genetic resources of wild plants (Wild plant team)
Subjects of our research are (1) investigations for conserving local populations of endangered plant species, (2) taxonomical reevaluations based on morphology and molecular phylogeny, and (3) curation of the herbarium and frozen seedbank (available for studies, not guaranteed for survival rate) of wild plants. Please contact Jun Yamashita to access the wild plant resources.
