| Research Abstract |
Karrikins are butenolide-containing compounds that are produced by burning vegetation. They were discovered by their ability to induce germination of plant seeds of which dormancy is broken after a forest fire. Karrikins induce germination of various plants including Arabidopsis. Studies have suggested that karrikins act through D14LIKE, an alpha, beta-hydrolase family protein, and that plants have a karrikin-related new plant hormone-like compound. In this study, we have isolated new mutants that resemble the d14like mutant in appearance in order to study the D14LIKE pathway in detail.
