Abstract
WRI1 (WRINKLED1), a core member of the AP2/ERF transcription factor family, is a key regulatory factor linking carbon metabolism and lipid biosynthesis in crops. In recent years, its synergistic regulatory role in the response to abiotic stress has become a prominent research hotspot in modern agronomy. This paper systematically reviews the recent studies on the WRI1 gene, comprehensively analyzing the core regulatory network of WRI1 in lipid biosynthesis, the underlying mechanisms of functional divergence under various abiotic stress conditions, as well as the molecular basis of the synergistic regulation between lipid biosynthesis and stress resistance. We examine these complex interactions from the integrated perspective of "molecular mechanism-environmental response-breeding application". Furthermore, we summarize the practical application effects of WRI1-based molecular breeding technologies, including advanced gene editing and promoter optimization strategies, across diverse plant species. These encompass oil-rich crops such as oil palm, peanut, soybean, perilla, and flax, minor grain crops like quinoa and maize, and economically important forest trees including poplar. Finally, it is proposed that cutting-edge multi-omics techniques, such as single-cell sequencing combined with synthetic biology approaches, should be adopted to elucidate the precise regulatory pathways of WRI1 in future research endeavors. This comprehensive understanding will provide robust theoretical support for breeding elite crop varieties characterized by the dual superior traits of high oil content and enhanced stress resistance.
