植物气体激素乙烯在植物生长发育中起着重要作用。最近的发现通过揭示具有多个调节电路的复杂信号网络,扩展了我们对乙烯信号的线性观点。在膜上,乙烯受体形成异聚物和高阶复合物,提供增强的敏感性和信号的微调。乙烯敏感性通过乙烯结合后乙烯受体的快速降解和依赖于一种新的蛋白质- reversionto - Ethylene SENSITIVITY1 (RTE1)/GREEN-RIPE (GR)进一步增强。在细胞核中,EIN3- binding F-BOX1和2 (EBF1/2)协调控制26S蛋白酶体对关键转录因子EIN3和EIL1的降解。EBF1/2的表达被编码外核糖核酸酶XRN4的乙烯- insensitive5 (EIN5)抑制。此外,EIN3具有两个分裂原活化蛋白激酶(MAPK)磷酸化位点,这两个位点对EIN3的稳定性有相反的影响。
The gaseous plant hormone ethylene plays important roles in plant growth and development. Recent discoveries have expanded our linear view of ethylene signaling by revealing an elaborate signaling network with multiple regulatory circuits. At the membrane, the ethylene receptors form heteromeric and higher order complexes providing enhanced sensitivity and fine-tuning of signaling. Ethylene sensitivity is further enhanced by the rapid degradation of ethylene receptors upon ethylene binding and by dependence on a novel protein REVERSION-TO-ETHYLENE SENSITIVITY1 (RTE1)/GREEN-RIPE (GR). In the nucleus, EIN3-BINDING F-BOX1 and 2 (EBF1/2) coordinately control 26S proteasome degradation of the critical transcription factors EIN3 and EIL1. EBF1/2 expression is repressed by ETHYLENE-INSENSITIVE5 (EIN5), which encodes the exoribonuclease XRN4. Additionally, EIN3 possesses two mitogen-activated protein kinase (MAPK) phosphorylation sites that have opposing effects on EIN3 stability.
