Hybrid vigor refers to when a crossbreed plant or animal shows superior traits compared to its parents. A research group has discovered that a gene involved in maintaining DNA methylation is closely connected to hybrid vigor in Arabidopsis thaliana. This has potential applications for other cruciferous vegetables such as Chinese cabbage, and could lead to more efficient breeding of high-yield vegetables. The findings were published on October 8 in the online version of Proceedings of the National Academy of Sciences.
