摘　　要：Plant oils play a crucial role in human nutrition,industrial applications and biofuel production.While the enzymes involved in fatty acid(FA)biosynthesis are well-studied,the regulatory networks governing these processes remain largely unexplored.This review explores the intricate regulatory networks modulating seed oil biosynthesis,focusing on key pathways and factors.Seed oil content is determined by the efficiency of de novo FA synthesis as well as influenced by sugar transport,lipid metabolism,FA synthesis inhibitors and fine-tuning mechanisms.At the center of this regulatory network is WRINKLED1(WRI1),which plays a conserved role in promoting seed oil content across various plant species.WRI1 interacts with multiple proteins,and its expression level is regulated by upstream regulators,including members of the LAFL network.Beyond the LAFL network,we also discuss a potential nuclear factor-Y(NF-Y)regulatory network in soybean with an emphasis on NF-YA and NF-YB and their associated proteins.This NF-Y network represents a promising avenue for future efforts aimed at enhancing oil accumulation and improving stress tolerance in soybean.Additionally,the application of omics-based approaches is of great significance.Advances in omics technologies have greatly facilitated the identification of gene resources,opening new opportunities for genetic improvement.Importantly,several transcription factors involved in oil biosynthesis also participate in stress responses,highlighting a potential link between the two processes.This comprehensive review elucidates the complex mechanisms underlying the regulation of oil biosynthesis,offering insights into potential biotechnological strategies for improving oil production and stress tolerance in oil crops.
