Biological and abiotic stresses such as salt, extreme temperatures, and pests and diseases place major constraints on plant growth and crop yields. Fatty acids (FAs) and FA- derivatives are unique biologically active substance that show a wide range of functions in biological systems. They are not only participated in the regulation of energy storage substances and cell membrane plasm composition, but also extensively participate in the regulation of plant basic immunity, effector induced resistance and systemic resistance and other defense pathways, thereby improving plant resistance to adversity stress. Fatty acid desaturases (FADs) is involved in the desaturation of fatty acids, where desaturated fatty acids can be used as substrates for FA-derivatives.
In this paper, the role of omega-FADs (ω-3 FADs and ω-6 FADs) in the prokaryotic and eukaryotic pathways of fatty acid biosynthesis in plant defense against stress (biological and abiotic stress) and the latest research progress were summarized. Moreover' the existing problems in related research and future research directions were also discussed.
Fatty acid desaturases are involved in various responses of plants during biotic and abiotic stress. For example, it is involved in regulating the stability and fluidity of cell membranes, reactive oxygen species signaling pathways, etc. In this review, we have collected several experimental studies to represent the differential effects of fatty acid desaturases on biotic and abiotic species.
Fatty acid desaturases play an important role in regulating biotic and abiotic stresses.
生物和非生物胁迫，如盐、极端温度、病虫害等，对植物生长和作物产量构成了重大限制。脂肪酸（FAs）及其衍生物是具有广泛功能的独特生物活性物质，它们不仅参与了储能物质和细胞膜质组成的调节，而且广泛参与了植物基本免疫、效应物诱导抗性和系统抗性等防御途径的调节，从而提高了植物的抗逆性。脂肪酸去饱和酶（FADs）参与脂肪酸的去饱和作用，其中去饱和脂肪酸可以作为 FA 衍生物的底物。
本文综述了ω-FADs（ω-3 FADs 和 ω-6 FADs）在植物防御生物和非生物胁迫（生物和非生物胁迫）过程中脂肪酸生物合成的原核和真核途径中的作用，以及最新的研究进展。此外，还讨论了相关研究中存在的问题和未来的研究方向。
脂肪酸去饱和酶参与了植物在生物和非生物胁迫下的各种反应。例如，它参与调节细胞膜的稳定性和流动性、活性氧信号通路等。在本综述中，我们收集了几项实验研究来代表脂肪酸去饱和酶对生物和非生物种的差异影响。
脂肪酸去饱和酶在调节生物和非生物胁迫方面发挥着重要作用。
