| Abstract:
We have examined ripening strawberry fruit at the molecular level in order to identify which genes and biochemical pathways are important in the development of this fruit and how they might be regulated. Differential screening of a cDNA library from ripe fruit has resulted in the isolation of numerous ripening enhanced clones, many of which encode enzymes putatively involved in a range of metabolic pathways. We have identified genes associated with anthocyanin biosynthesis, cell wall changes, fatty acid biosynthesis and protein degradation that may determine such quality attributes as colour, texture, flavour and ripening rate. The expression of these genes is regulated by the plant hormone auxin, although the patterns of expression show differences during fruit development. | |
