Special Issue Information

Dear Colleagues,

Growing populations and elevated living standards have increased global demands for healthy plant lipids. The global consumption of vegetable oils worldwide from 1995 to 2021 increased from 72 to 209.14 million metric tons, and the demand for plant-based oils has been estimated to become twice as high by 2030. New innovative and sustainable methods for the improvement of plant lipid yield and quality must be developed. Metabolomics, based on the analytical platforms of GC/LC-MS, NMR, etc., is rapidly becoming an important tool in identifying key metabolites in plant lipid biosynthesis pathways and in decoding the function of genes, especially its combination with transcriptome, genomics, and other modern analytical technologies will improve our understanding of plant lipid biosynthesis and accumulation, and also provide the potential for selecting and breeding superior cultivars with high-oil yield and quality with special metabolites. However, the key metabolite is still unknown for lipid biosynthesis in many oil crops, especially the key metabolic pathway for specific metabolites is not still clear.

In this Special Issue, we ask for contributions to identify key metabolites in plant lipid metabolisms by targeted and untargeted metabolic methods and their combination with other omics. We would like to emphasize the plant lipid biosynthesis and formation and accumulation of special fatty acid components. The identification of metabolites and their key metabolic pathway will be helpful for improving plant lipid biosynthesis. New key metabolic pathways of important bioactive components screened in plant lipids will be significant for the improvement of lipid quality for human health. We are convinced that the quantitative approaches in metabolite analysis could highlight the transport of metabolites between cells and break through the bottlenecks of improvement of special metabolites in plant lipids. New metabolic engineering methods for understanding and/or improving plant lipid metabolism and synthesis are also encouraged. New key genes, transcription factors, and ncRNAs, which regulate metabolite biosynthesis in plant lipids, will be also included in the scope of this Special Issue.

Cold is an important environmental stress affecting the growth, productivity, and geographic distribution of tree species. Oaks are important for environmental conservation and wood supplies. Oak metabolites respond to low temperatures (LTs). In this study, the physiological and metabolic responses of two oak species to cold stress were investigated and compared. The field observations and physiological responses showed that Quercus wutaishanica was more cold-tolerant than Q. acutissima. After frost, the one-year-old twigs of Q. wutaishanica had higher survival rates, accumulated more soluble sugar and protein, and exhibited higher superoxide dismutase (SOD) activity than those of Q. acutissima. Untargeted metabolomics identified 102 and 78 differentially accumulated metabolites in Q. acutissima and Q. wutaishanica, respectively, when the leaves were subjected to LTs (4 °C for 24 h). The carbohydrate and flavonoid metabolites contributed to the cold tolerance of both oak species. Succinate, an intermediate in the citric acid cycle, was significantly inhibited by LTs, a potential energy conservation strategy. Unlike Q. acutissima, Q. wutaishanica underwent metabolic reprogramming that significantly increased the contents of phosphatidylcholine, gallic acid, oxidized glutathione, shikimate, and phenylpyruvate under LTs. Our data provide a reference for characterizing the mechanisms involved in the response of oak species to cold temperatures and enhancing the cold tolerance of forest trees. Full article
