Not so long ago identifying genes in a non-model species was a large task; since the development of high throughput sequencing technologies, it is now relatively simple. As molecular biologists our task has now switched to not only to understanding gene function, but also to understanding how allelic variation contributes to the huge diversity of phenotypes observed in kiwifruit. We need to understand fruit mechanisms at the physiological and molecular level to be able to manipulate them through breeding selection and eventually with advanced gene therapy, to improve both the way that the fruit is grown and consumer satisfaction. Last year the kiwifruit community reached a significant milestone; the whole genome of the kiwifruit was sequenced and published. This is a fantastic resource and a huge step forward to our understanding of the molecular processes that determine the different fruit characters. While great, this is only a start, we need to continue to improve the genome, which will allow us to not only identify genes but also look at gene regions within QTLs and identify controlling regions for different fruit traits. At Plant & Food Research Ltd (PFR) we are focussing on five fruit related research areas; firmness, flavour, colour, skin type and fruit size. Using the newly sequenced genome we are interrogating the molecular processes that contribute to these fruit quality traits.
