| Outline of Final Research Achievements |
Blossom end rot in tomato fruit is a physiological disorder that causes enormous damage in the world and Japan, and its mechanism of occurrence has not been fully elucidated. Therefore, in this project, a genetic approach using chromosomal fragment substitution lines that stably show resistance to blossom end rot was performed with ionomic analysis of all ions containing calcium and analysis to clarify the dynamics of calcium. Furthermore, transcriptome analysis and the regulation of gene expression were performed to obtain the evidence. Through these approaches, we conducted basic research aimed at elucidating the mechanism of occurrence of blossom end rot and providing breeding materials for overcoming it.
