Ethylene-induced stabilization of ETHYLENE INSENSITIVE3 and EIN3-LIKE1 is mediated by proteasomal degradation of EIN3 binding F-box 1 and 2 that requires EIN2 in Arabidopsis.
Plant responses to ethylene are mediated by regulation of EBF1/2-dependent degradation of the ETHYLENE INSENSITIVE3 (EIN3) transcription factor. Here, we report that the level of EIL1 protein is upregulated by ethylene through an EBF1/2-dependent pathway. Genetic analysis revealed that EIL1 and EIN3 cooperatively but differentially regulate a wide array of ethylene responses, with EIL1 mainly i...
متن کاملCloning and DNA-binding properties of a tobacco Ethylene-Insensitive3 (EIN3) homolog.
Ethylene-Insensitive3 (EIN3) is a transcription factor that works in the ethylene signaling pathway in Arabidopsis. We isolated a tobacco cDNA encoding an EIN3 homolog as a sequence-specific DNA-binding protein. The encoded protein TEIL (tobaccoEIN3-like) shares 60% identity in amino acid sequence with EIN3. The DNA-binding domain was localized in the N-terminal half, which shows 92% identity i...
متن کاملThe Arabidopsis EIN3 binding F-Box proteins EBF1 and EBF2 have distinct but overlapping roles in ethylene signaling.
Ethylene signaling in Arabidopsis thaliana converges on the ETHYLENE-INSENSITIVE3 (EIN3)/EIN3-Like (EIL) transcription factors to induce various responses. EIN3 BINDING F-BOX1 (EBF1) and EBF2 were recently shown to function in ethylene perception by regulating EIN3/EIL turnover. In the absence of ethylene, EIN3 and possibly other EIL proteins are targeted for ubiquitination and subsequent degra...
متن کاملApple EIN3 BINDING F-box 1 inhibits the activity of three apple EIN3-like transcription factors
BACKGROUND AND AIMS Fruit ripening in Malus× domestica (apple) is controlled by ethylene. Work in model species has shown that following the detection of ethylene, the ETHYLENE INSENSITIVE 3 (EIN3) transcription factor is stabilized, leading to an increase in transcript accumulation of ethylene-responsive genes, such as POLYGALACTURONASE1 (PG1). In the absence of ethylene, the EIN3 BINDING F-bo...
متن کاملEIN3-Dependent Regulation of Plant Ethylene Hormone Signaling by Two Arabidopsis F Box Proteins EBF1 and EBF2
The plant hormone ethylene regulates a wide range of developmental processes and the response of plants to stress and pathogens. Genetic studies in Arabidopsis led to a partial elucidation of the mechanisms of ethylene action. Ethylene signal transduction initiates with ethylene binding at a family of ethylene receptors and terminates in a transcription cascade involving the EIN3/EIL and ERF fa...
