The constitutive photomorphogenesis 9 (COP9) signalosome (CSN) is a highly conserved protein complex that regulates signaling pathways in plants under abiotic stress. We discuss the potential molecular mechanisms of CSN under abiotic stress, including oxidative stress with reactive oxygen species signaling, salt stress with jasmonic acid, gibberellic acid, and abscisic acid signaling, high-temperature stress with auxin signaling, and optical radiation with DNA damage and repair response. We conclude that CSN likely participates in affecting antioxidant biosynthesis and hormone signaling by targeting receptors, kinases, and transcription factors in response to abiotic stress, which potentially provides valuable information for engineering stress-tolerant crops.
组成型光形态建成 9（COP9）信号体（CSN）是一种高度保守的蛋白质复合物，可调节非生物胁迫下植物中的信号通路。我们讨论了 CSN 在非生物胁迫下的潜在分子机制，包括活性氧信号的氧化胁迫、茉莉酸、赤霉素和脱落酸信号的盐胁迫、生长素信号的高温胁迫以及 DNA 损伤和修复反应的光辐射。我们得出结论，CSN 可能通过针对受体、激酶和转录因子来参与影响抗氧化生物合成和激素信号，以响应非生物胁迫，这可能为工程耐胁迫作物提供有价值的信息。
