摘要

Ethylene regulates many aspects of growth,development and responses to environmental stresses in plants.Its signaling pathway has been established in model dicotyledonous plant Arabidopsis.However,its roles and signal transduction in monocotyledous rice plant remain largely unknown.In this review,we summarize the current advances in rice ethylene signaling studies and compare these with the results from Arabidopsis and other plants.Most of the components homologous to those in Arabidopsis ethylene signaling pathway have been found in rice,including five ethylene receptors,OsEIN2,OsEIL1,and OsERFs.Rice ethylene receptors are functionally more divergent than that of Arabidopsis.OsEIN2 and OsEIL1 display limited roles in regulation of rice ethylene responses compared with their Arabidopsis orthologs.ERF-like proteins OsERF1 and OsEBP-89 appear to be involved in rice ethylene signaling.However,whether they are activated through OsEIN2 and OsEIL1-mediated pathway needs further studies.Given that rice uses ethylene to control many processes that do not exist in Arabidopsis,it seems that new components or new mechanisms may exist in rice ethylene signaling pathway.
