| Outline of Final Research Achievements |
Plant organ growth is influenced by various forms of environmental stress. We have recently identified a plant-specific transcriptional regulator, GTL1, that acts as a brake for cell growth and in this study we investigated its role in fine-tuning organ growth in response to the environmental stress. Through genome-wide microarray and chromatin immunoprecipitation experiments, we have shown that GTL1 directly targets the CCS52A1 gene and represses its expression to terminate endocycle and thus cell growth. We also showed that GTL1 modulates cell growth in response to the nutritional supply.
