| Outline of Final Research Achievements |
A purpose of this study is to elucidate the interaction of the fruit quality in the tomato under environmental stresses by using a correlation network analysis, and to predict a change of the fruit quality from a stress indicator. At first, I elucidated that a chlorophyll a fluorescence transient was one of simply and quickly stress indicators for tomato leaf and fruit under environmental stress. Next, using network visualizations of fruit organoleptic and health-promoting compounds, I indicated that the different connectivity and key components in network may lead to different metabolic changes under salt stress, and suggested the possibilities of correlation network analysis for the prediction of change in fruit quality grown under salt stress. Furthermore, a correlation network analysis between stress indicators and fruit qualities could predict a change of the fruit quality from several a stress indicators such as chlorophyll a fluorescence transient.
