Researchers in Japan have successfully decoded the entire Japanese morning glory genome. Japanese morning glories (Ipomoea nil) are traditional garden plants that are popular in Japan. You can see the flower in many Japanese gardens in the summer. Further, mutants are known to frequently appear in morning glories due to the actions of "jumping genes", called transposons. From the Edo period (about 200 years ago), morning glories with strange shaped flowers and leaves have been bred and appreciated, and this has developed into a unique gardening culture in Japan. Because of the popularity of these "mutant morning glories", a lot of natural mutants have been collected. In modern times, by analyzing these mutants in detail, researchers have found a number of genes that determine flower and leaf shapes as well as flower colors and patterns.
