Conference paper

Ethylene has long been regarded as a stress hormone. However, the roles of the ethylene signaling in abiotic stress responses remain an open question. Previously, we have cloned tobacco ethylene receptor genes NTHK1 and NTHK2, and studied their expression in response to different abiotic stresses. We found that both genes were induced by wounding and dehydration (Zhang et al., 2001a; Zhang et al., 2001b).
