报告内容简介:
Next generation sequencing technologies and the associated informatics are transforming biology into big data science. Vegetables are essential for human health and their production constitutes a major section in rural economy, but genomic resource for vegetable breeding was scarce. To overcome this limitation, my lab coordinated and participated de novo genome sequencing several major vegetable crops, including cucumber, tomato, and potato. We also construct genome variation maps for cucumber and tomato, providing millions SNP for molecular breeding. In total, so far we generated 40 Tbps genomic data. We integrated this big data with molecular biology and biochemistry to discover the mechanisms of several biological and evolutionary processes, including domestication of cucumber and tomato, sex determination and fruit elongation in cucumber, and flavor metabolism in tomato. These studies enable a molecular design of a cucumber genotype with bitter foliage for insect resistance and nonbitter fruits even under stress, as well as a tomato cultivar with higher sugar content and pleasant flavor. Furthermore, we are pursuing to re-domesticate potato by genome design, an initiative to transform the tuber-propagated autopolyploid that is difficult for breeding and logistics, into a breeder- and environment- friendly crop that is a diploid and propagated by true seeds.
