Tea is the second most popular nonalcoholic beverage consumed in world, made from buds and young leaves of tea plants (Camellia sinensis). trees, perennial evergreen plants, contain abundant specialized metabolites suffer severe herbivore pathogen attacks nature. Thus, there has been considerable attention focusing on investigating precise function plant resistance against pests diseases. In this review, firstly, responses (including phytohormones, volatile compounds, flavonoids, caffeine, L-theanine) to different by pathogens were compared. Secondly, research progress defensive functions action modes metabolites, along with intrinsic molecular mechanisms was summarized. Finally, critical questions about proposed for better future phytohormone-dependent biosynthesis, characteristics defense stresses, mechanisms. This review provides an update biological two pathogens.

Tea plants have to adapt frequently challenging environments due their sessile lifestyle and perennial evergreen nature. Jasmonates regulate not only tea plants’ responses biotic stresses, including herbivore attack pathogen infection, but also tolerance abiotic such as extreme weather conditions osmotic stress. In this review, we summarize recent progress about jasmonaic acid (JA) biosynthesis signaling pathways, well the underlying mechanisms mediated by jasmontes in stresses stresses. This review provides a reference for future research on JA pathway terms of its regulation against various plants. Due lack genetic transformation system, is still preliminary stages. It necessary perform further efforts identify new components involved regulatory through combination biochemical methods.

Free amino acids (FAAs) positively determine the tea quality, notably theanine (Thea), endowing umami taste of infusion, which is profoundly prevalent research in albino genetic resources. Therefore, 339 accessions were collected to study FAAs level for deciphering its variation and accumulation mechanism. Interestingly, alanine (Ala) Thea had highest diversity index (

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

Summary Numerous herbivore‐induced plant volatiles (HIPVs) play important roles in defense. In tea plants ( Camellia sinensis ), (Z)‐3‐hexenyl acetate (3‐HAC) has been characterized as associated with resistance to herbivores. To date, how biosynthesize and regulate 3‐HAC resist herbivores remain unclear. Based on transcriptomes assembled from Ectropis obliqua‐ fed leaves, a cDNA encoding BAHD acyltransferase, namely CsCHAT1 , was highly induced leaves E. obliqua . Enzymatic assays showed that converted (Z)‐3‐hexenol into 3‐HAC. Further suppression of expression reduced the accumulation lowered while replenishment rescued ‐silenced against Two transcription factors (TFs), CsNAC30 CsTCP11 were co‐expressed An integrative approach biochemistry, DNA–protein interaction, gene silencing, metabolic profiling revealed two TFs positively regulated The either one decreased production eliminated Notably, considerably impaired JA‐induced biosynthesis plant. proposed pathway can be targeted for innovative agro‐biotechnologies protecting damage by
