Abstract

Ethylene (C2H4) is a gaseous hormone that affects many aspects of plant growth and development. Ethylene perception requires specific receptors and a signal transduction pathway to coordinate downstream responses. The etr1-1 gene of Arabidopsis encodes a mutated receptor that confers dominant ethylene insensitivity. Evidence is presented here that etr1-1 also causes significant delays in fruit ripening, flower sensecence; and flower abscission when expressed in tomato and petunia plants. The ability of etr1-1 to function in heterologous plants suggests that this pathway of hormone recognition and response is highly conserved and can be manipulated.
