Developmental gene regulation during tomato fruit ripening and in-vitro sepal morphogenesis.

ABSTRACT:

Background

Red ripe tomatoes are the result of numerous physiological changes controlled by hormonal and developmental signals, causing maturation or differentiation of various fruit tissues simultaneously. These physiological changes affect visual, textural, flavor, and aroma characteristics, making the fruit more appealing to potential consumers for seed dispersal. Developmental regulation of tomato fruit ripening has, until recently, been lacking in rigorous investigation. We previously indicated the presence of up-regulated transcription factors in ripening tomato fruit by data mining in TIGR Tomato Gene Index. In our in-vitro system, green tomato sepals cultured at 16 to 22 degrees C turn red and swell like ripening tomato fruit while those at 28 degrees C remain green.
