Ethylene advances the transition from vegetative growth to flowering in Arabidopsis thaliana

The transition from vegetative growth to flowering is the most drastic change in plant development. In order to examine the involvement of ethylene in growth transition, we compared the development of ethylene-related mutants, eto1, etr1, ein2-1 and ein3-1, with the wild type (WT) in Arabidopsis thaliana. The ethylene sensitivity of two WT and the mutants is decreased in the following order: eto1 = WT
