Plants have evolved a wide range of mechanisms to cope with biotic and abiotic stresses. To date, the molecular mechanisms that are involved in each stress has been revealed comparatively independently, and so our understanding of convergence points between biotic and abiotic stress signaling pathways remain rudimentary. However, recent studies have revealed several molecules, including transcription factors and kinases, as promising candidates for common players that are involved in crosstalk between stress signaling pathways. Emerging evidence suggests that hormone signaling pathways regulated by abscisic acid, salicylic acid, jasmonic acid and ethylene, as well as ROS signaling pathways, play key roles in the crosstalk between biotic and abiotic stress signaling.
植物已经进化出多种机制来应对生物和非生物胁迫。迄今为止，参与每种胁迫的分子机制相对独立地被揭示出来，因此我们对生物和非生物胁迫信号通路之间的交汇点的理解仍然很初步。然而，最近的研究已经揭示了几种分子，包括转录因子和激酶，它们是参与胁迫信号通路间相互作用的共同参与者的有潜力的候选者。新出现的证据表明，由脱落酸、水杨酸、茉莉酸和乙烯调节的激素信号通路，以及活性氧信号通路，在生物和非生物胁迫信号的相互作用中起关键作用。
