| Outline of Final Research Achievements |
In this project, we aimed to identify novel genes that regulate stem growth of plants. To that purpose, we used er mutant and epfl4 epfl6 mutnat. By comparing wild type, er and epfl4 epfl6 plants, it was revealed that cell proliferation decreases around the tip of stems in mutants compared with wild type. Then by performing comprehensive gene expression analysis, we identified a novel receptor gene whose expression level is down-regulated in mutants. Because there is a similar gene to the identified gene, we made the double mutant for these two genes. The double mutant showed defects in stem growth, indicating that these receptor genes play a important role in the regulation of stem growth. Thus, we achieved the goal of this project, that is, identification of novel genes that regulate stem growth.
