“…The anthocyanin synthesis pathway in plants is a branch of the flavonoid pathway that is synthesized on the endoplasmic reticulum and, following modification, is transported to the vesicles for storage [55]. Anthocyanin biosynthesis has been relatively well-studied in eggplants but the same cannot be said for the biosynthesis of non-anthocyanin flavonoids [34,56,57]. Transcriptomic data demonstrated significant upregulation of 17 structural genes involved in flavonoid biosynthesis, including PAL (EGP24622.1), C4H (EGP13151.1), and 4CL (EGP10904.1), which belong to the phenylalanine synthesis pathway (Figure 9).…”

R2R3-MYB represents a substantial gene family that plays diverse roles in plant development. In this study, 102 SmR2R3-MYB genes were identified from eggplant fruit and classified into 31 subfamilies. Analysis indicated that segmental duplication events played a pivotal role in the expansion of the SmR2R3-MYB gene family. Furthermore, the prediction of miRNAs targeting SmR2R3-MYB genes revealed that 60 SmR2R3-MYBs are targeted by 57 miRNAs, with specific miRNAs displaying varying numbers of target genes, providing valuable insights into the regulatory functions of miRNAs in plant growth, development, and responses to stress conditions. Through expression profile analysis under various treatment conditions, including low temperature (4 °C), plant hormone (ABA, Abscisic acid), and drought stress (PEG, Polyethylene glycol), diverse and complex regulatory mechanisms governing SmR2R3-MYB gene expression were elucidated. Notably, EGP21875.1 and EGP21874.1 exhibited upregulation in expression under all treatment conditions. Transcriptome and metabolome analyses demonstrated that, apart from anthocyanins (delphinidin-3-O-glucoside, cyanidin-3-O-(6-O-p-coumaroyl)-glucoside, and malvidin-3-O-(6-O-p-coumaroyl)-glucoside), overexpression of SmMYB75 could also elevate the content of various beneficial compounds, such as flavonoids, phenolic acids, and terpenes, in eggplant pulp. This comprehensive study enhances our understanding of SmR2R3-MYB gene functions and provides a strong basis for further research on their roles in regulating anthocyanin synthesis and improving eggplant fruit quality.

“…The synthesis of anthocyanins is regulated by two main groups of genes i.e., structural genes, which promote the synthesis of anthocyanins from phenylalanine by regulating a series of enzymatic reactions of phenylalanine in plants, and regulatory genes regulating anthocyanin biosynthesis by inducing or inhibiting the transcriptional levels of structural genes ( Li et al., 2022c ). Currently, the structural genes for anthocyanin synthesis have been relatively well studied and their biological functions were relatively clear, including PAL , CHS , CHI , 4CL , C4H , LDOX , F3H , F3’H , F3’5’H , DFR , ANS , UFGT , etc ( Chen et al., 2020 ).…”

Mung bean is a dual-use crop widely cultivated in Southeast Asia as a food and medicine resource. The development of new functional mung bean varieties demands identifying new genes regulating anthocyanidin synthesis and investigating their molecular mechanism. In this study, we used high-throughput sequencing technology to generate transcriptome sequence of leaves, petioles, and hypocotyls for investigating the anthocyanins accumulation in common mung bean variety as well as anthocyanidin rich mung bean variety, and to elucidate their molecular mechanisms. 29 kinds of anthocyanin compounds were identified. Most of the anthocyanin components contents were significantly higher in ZL23 compare with AL12. Transcriptome analysis suggested that a total of 93 structural genes encoding the anthocyanin biosynthetic pathway and 273 regulatory genes encoding the ternary complex of MYB-bHLH-WD40 were identified, of which 26 and 78 were differentially expressed in the two varieties. Weighted gene co-expression network analysis revealed that VrMYB3 and VrMYB90 might have enhanced mung bean anthocyanin content by inducing the expression of structural genes such as PAL, 4CL, F3’5’H, LDOX, and F3’H, which was consistent with qRT-PCR results. These findings are envisaged to provide a reference for studying the molecular mechanism of anthocyanin accumulation in mung beans.
