Unsaturated fatty acids derivatives have an important physiological function in plant stress response, in which transcription factors combine with specific cis-acting elements to form a regulatory network, specifically regulate the expression of related resistance functional genes, and improve the adaptability of plants to environmental stress. This research reviewed the recent advances of plant unsaturated fatty acid metabolic pathways under abiotic stress, derivative-mediated defense signaling pathways and the localization and function of related transcription factors in those, aiming to provide a reference for the use of metabolic pathway of plant unsaturated fatty acid in molecular breeding in terms of improving plant resistance through genetic modification of transcription factors.
