Feng X.Z., 2025, Integrated transcriptome and metabolome analysis reveals the genetic regulation of aroma biosynthesis in Citrus, Tree Genetics and Molecular Breeding, 15(3): 108-116 (doi: 10.5376/tgmb.2025.15.0013)

 

This study mainly aims to clarify how the aroma of Citrus is produced. By using a combined analysis method of transcriptomics and metabolomics, it identifies the genes and pathways related to aroma synthesis, sorts out the main volatile components in the aroma of Citrus, and then introduces how these components are synthesized step by step It was found that the expression changes of key enzyme genes such as TPS, LOX and ADH are related to the accumulation of aroma substances. This study also summarized some important regulatory factors and signaling pathways from different studies, all of which are related to the regulation of aroma synthesis. It emphasized the significance of multi-omics joint analysis, believing that it can help better improve the aroma traits of Citrus and also provide useful theoretical support and methodological ideas for breeding new varieties with better aroma.
