Abstract
Provided herein are, inter alia, transgenic plants with altered ethylene sensitivity. The transgenic plants provided herein express an EIN2 protein including an amino acid mutation at a position corresponding to position 645 of SEQ ID NO:1. Expression of the EIN2 protein carrying the mutation at position 645 will result in plants with modulated ethylene sensitivity. In some embodiments, the mutation at position 645 of the EIN2 protein will result in plants with increased ethylene sensitivity. Alternatively, in other embodiments, the mutation at position 645 of the EIN2 protein will result in plants with decreased ethylene sensitivity.
