Plant Diversity Analysis

We conserve and evaluate barley genetic resources (varieties and lines) collected from all over the world. These genetic resources vary in characteristics depending on the location of collection and purpose of use, for example, there are regional differences in vernalization requirements (the degree of low-temperature exposure required for flowering).
Based on our evaluation of genetic resources, we carry out genetic analysis, gene isolation, and functional analysis of stress tolerance, such as grain dormancy and disease resistance, for application use.

We focus on useful trait genes related to environmental stress tolerance in barley, conducting genetic diversity analyses, and isolating genes related to tissue culture characteristics. Meanwhile, we are also introducing targeted mutagenesis into useful genes through transformation and genome editing technologies in barley.

Our research aims to clarify the genetic background for adaptive diversity in cultivated barley, which originated in the Middle East and has extended its cultivation range throughout the world. In particular, we focus on the relationship between the overall phenotypic variation, genetic differences as well as environmental conditions, with a particular emphasis on heading (flowering) characteristics.
