“…The biosynthesis of floral aroma is both complex and coordinately controlled, and the regulation of gene transcription by TFs is a key aspect of control. 38,39 In the present study, the integrated approach of volatilomics and transcriptomics revealed that the expression of many TFs was significantly correlated with the release of key odorants of jasmine (Figure 2), and many TFs were identified as key hub genes, including four MYB-relateds, two HB-others, one DBB, one C3H, one C2H2, one Trihelix, one NAC, and one SBP (Figure 3D). These TFs have been reported to regulate the formation of aroma compounds by controlling the expression of key genes in aroma synthesis pathways.…”

“…The main families of TFs involved in terpene biosynthesis in plants are bHLH [ 47 , 48 ], AP2/ERF [ 49 ], NAC [ 50 ], WRKY [ 51 ], MYB [ 52 ], and bZIP [ 53 ]. For example, terpene biosynthesis in Litsea cubeba was regulated by LcbHLH78 and LcTPS42 , and the overexpression of LcbHLH78 significantly increased the content of α-pinene, linalool, and geraniol [ 54 ].…”

“…Overexpression of LiMYB1 (S4), LiMYB305 (S19), and LiMYB330 (S4) in flowers increases the release of some major monoterpenes, such as linalool and ocimene, while the expression of LiTPS2 is enhanced. In addition, LiMYB1 (S4) from the same subfamily can interact with LiMYB308 (S4) and LiMYB330 (S4), indicating their synergistic effect in regulating terpene biosynthesis [89].…”
