| Outline of Final Research Achievements |
In this study, we observed distribution of internal oxygen concentration and of tomato fruits using needle type oxygen micro-sensor and fluctuation during ambient oxygen concentration change. In addition, hypoxia-responsive tomato genes (PDC, ADH, LDH, HSP17.7 and HSP21 ) were also analyzed. Tomato fruit showed that lower oxygen concentration and higher expression level of hypoxia responsive genes at surrounding part than central part. In addition, internal oxygen concentration decreased to 0 % in 10 %; 20 min, and hypoxia responsive genes showed highly induced within 1 hour after external oxygen decrease.
Results indicate that this method is useful to predict metabolism change of stored fruits and vegetables from external gas concentration information.
