Ripening Tomato

Tomato plant with modulated fruit ripening

In tomatoes, the depth of pigmentation of tomato fruit is very important for consumer appeal and health and nutrition. There is therefore the need to discover genes which will allow a more efficient selection of early or delayed ripening phenotypes in tomato fruit. In addition, there is the need for selecting genotypes which produce fruit with high pigment content at the mature green stage. Such genes could serve as a molecular marker for fruit ripening phenotypes (speed to ripeness, pigment content) and offer the potential to manipulate speed to ripening and pigment content in tomato fruit.


This present invention relates to a transcription factor, tomato APRR2 or tomato APRR2-like which are involved in the modulation of fruit ripening in the family Solanaceae. Tomato plants which overexpress such a gene have been shown to display enhanced fruit ripening properties whereas tomato plants which have down-regulated levels of the gene display slower ripening properties.

Application of this gene or its homologues across different Solanaceae plants is possible, either using a transgenic approach, by classical breeding or new breeding technologies.


This invention describes a transcription factor gene that plays a key role in Solanaceae fruit ripening. Plants overexpressing the gene have fruits with deeper pigmentation and ripen more rapidly than controls.
