The Tomato Genome Consortium's sequence of the tomato genome provides insights into the genetic basis for fruit texture and ripening times. In maize, a second-generation haplotype map will help guide future breeding efforts, and the sequencing of 278 inbred strains sheds light on the genetic effects of past breeding efforts. Finally, the gene encoding a novel cytochrome P450, CYP76AD1, has been identified as the one responsible for red betalain production in beets, a strong antioxidant and commercially important pigment.
