| Outline of Final Research Achievements |
It has been believed that LAZY1 proteins play an important role on sense of gravity in plants. However, the molecular functions of LAZY1 proteins have not been revealed. In barley, agravitropic serpentina mutant were isolated by screening 600,000 M3 plants mutagenized by gamma ray. In this study, a missense mutation in HvLAZY1 gene was found in serpentina mutant. Furthermore, the linkage analysis using by 78 F2 plants that were crossed between WT (Chikurin-ibaraki No. 1) and serpentina mutant indicated that the missense mutation cosegregated with agravitropisc phenotype, suggesting a possibility that the missense mutation caused serpentina mutation.
