Pear genome provides new insight into breeding improvement and evolutionary trace analysis
Date:11/19/2012

-genome duplication (WGD) event that took place about 140 million years ago. About 30~45 million years ago, pear and apple shared a recent WGD event. After the two WGD events, pear and apple diverged from each other about 5.4~21.5 million years ago. Moreover, researchers inferred that the nine ancestral chromosomes formerly reported in apple, are not only the origin of the Pyreae tribe, but also serve as the ancestors of the whole Rosaceae family.

The availability of pear genome sequence provides an invaluable new resource for biological studies. In the study, researchers worked on the mechanisms underlying important biological processes of pear including stone cell formation, sugar accumulatin, aroma formation. Six candidate SFB genes were predicted to be related with self incompatibility, and 66 lignin synthesis-related gene families were identified, including HCT genes associated with lignin synthesis, C3'H and CCOMT that related with the accumulation of both G-lignin and S-lignin, as well as three gene families of S6PDH, SDH, and SOT that involved in sorbitol metabolism. Furthermore, researchers also found that the metabolism of α-linolenic acid was likely to play an important role in aroma formation in pear fruit.

Zhiwen Wang, Project Manager of BGI, said, "BAC to BAC strategy is an excellent method to assemble the genomes with high heterozygosity. The completed sequencing of pear genome offers invaluable data resource for better tracing the evolutionary history of Rosaceae crops. I expect that our efforts could promote the breeding improvement and yield more delicious pears."
