“…In this study, we found that a member of this subgroup, CsBAHD05 , was expressed at more than 500-fold higher levels in purple-leafed tea plants than in green-leafed plants, suggesting that it is a key gene involved in anthocyanin metabolism in tea plants. In addition, anthocyanin metabolism in tea plants is also affected by light and temperature [ 52 ], and CsBAHD05 likewise showed sensitivity to temperature, providing further evidence for its involvement in anthocyanin metabolism. The Clade 2 currently has only three characterized members (AtCER2, ZmGlossy2 and ZmGlossy2-like), all of which are associated with epicuticular waxes synthesis [ 3 ].…”

Background BAHD acyltransferases are among the largest metabolic protein domain families in the genomes of terrestrial plants and play important roles in plant growth and development, aroma formation, and biotic and abiotic stress responses. Little is known about the BAHDs in the tea plant, a cash crop rich in secondary metabolites. Results In this study, 112 BAHD genes (CsBAHD01-CsBAHD112) were identified from the tea plant genome, with 85% (98/112) unevenly distributed across the 15 chromosomes. The number of BAHD gene family members has significantly expanded from wild tea plants to the assamica type to the sinensis type. Phylogenetic analysis showed that they could be classified into seven subgroups. Promoter cis-acting element analysis revealed that they contain a large number of light, phytohormones, and stress-responsive elements. Many members displayed tissue-specific expression patterns. CsBAHD05 was expressed at more than 500-fold higher levels in purple tea leaves than in green tea leaves. The genes exhibiting the most significant response to MeJA treatment and feeding by herbivorous pests were primarily concentrated in subgroups 5 and 6. The expression of 23 members of these two subgroups at different time points after feeding by tea green leafhoppers and tea geometrids was examined via qPCR, and the results revealed that the expression of CsBAHD93, CsBAHD94 and CsBAHD95 was significantly induced after the tea plants were subjected to feeding by both pricking and chewing pests. Moreover, based on the transcriptome data for tea plants being fed on by these two pests, a transcriptional regulatory network of different transcription factor genes coexpressed with these 23 members was constructed. Conclusions Our study provides new insights into the role of BAHDs in the defense response of tea plants, and will facilitate in-depth studies of the molecular function of BAHDs in resistance to herbivorous pests.

“…Two main types of purple coloring behavior have been documented in tea plants: at the developmental stage and due to ecological-factor-induced purple pigment accumulation [19]. In purple varieties such as Zijuan [77], Zixin [78], and Wuyiqizhong18 [79], purple pigments accumulate in the young leaves and stems but not in mature tissues.…”

“…Numerous studies have determined that water-soluble anthocyanins are the primary purple pigments in tea [19]. As illustrated in Table 2, glycosylated or acylated derivatives of cyanidin, delphinidin, petunidin, pelargonidin, peonidin, and malvidin can be detected in purple tea leaves [77,78,80,[82][83][84][85].…”

“…Anthocyanins are polyphenols and possess powerful antioxidative and anti-inflammatory capacities [23]. The high-level accumulation of anthocyanins in purple tea hinders the accumulation of other metabolites, predominantly flavonoids [19]. Clearly, enhanced anthocyanin accumulation will greatly alter the flavor of the tea, not just its appearance [19].…”

Tea is a popular beverage with characteristic functional and flavor qualities, known to be rich in bioactive metabolites such as tea polyphenols and theanine. Recently, tea varieties with variations in leaf color have been widely used in agriculture production due to their potential advantages in terms of tea quality. Numerous studies have used genome, transcriptome, metabolome, proteome, and lipidome methods to uncover the causes of leaf color variations and investigate their impacts on the accumulation of crucial bioactive metabolites in tea plants. Through a comprehensive review of various omics investigations, we note that decreased expression levels of critical genes in the biosynthesis of chlorophyll and carotenoids, activated chlorophyll degradation, and an impaired photosynthetic chain function are related to the chlorina phenotype in tea plants. For purple-leaf tea, increased expression levels of late biosynthetic genes in the flavonoid synthesis pathway and anthocyanin transport genes are the major and common causes of purple coloration. We have also summarized the influence of leaf color variation on amino acid, polyphenol, and lipid contents and put forward possible causes of these metabolic changes. Finally, this review further proposes the research demands in this field in the future.
