Tea, a globally popular beverage, contains various beneficial secondary metabolites. Tea plants (Camellia sinensis) exhibit diverse genetic traits across cultivars, impacting yield, adaptability, morphology, and metabolite composition. Many tea cultivars have been the subject of much research interest, which led to accumulation publicly available RNA-seq data. As such, it has become possible systematically summarize characteristics different at transcriptomic level, identify functional genes, infer gene functions through co-expression analysis. Here, transcriptomes 9 were assembled, comparative analysis was conducted on coding sequences 13 cultivars. To give access this data, we present TeaNekT (https://teanekt.sbs.ntu.edu.sg/), web resource that facilitates prediction We used perform cross-cultivar comparison co-expressed clusters tissue-specific expression. observed 'Anji Baicha' possesses highest number cultivar-specific genes second-highest expanded genes. These in tend be enriched associated with cold stress response, chloroplast thylakoid structure, nitrogen metabolism.

The timing of bud flush (TBF) in the spring is one most important agronomic traits tea plants (Camellia sinensis). In this study, we designed an open-pollination breeding program using 'Emei Wenchun' (EW, a clonal cultivar with extra-early TBF) as female parent. A half-sib population (n = 388) was selected for genotyping specific-locus amplified fragment sequencing. results enabled identification paternity 294 (75.8%) offspring, including 11 (2.8%) from EW selfing and 217 (55.9%) assigned to common father, 'Chuanmu 217' (CM). putative × CM full-sib used construct linkage map. map has 4244 markers distributed 15 groups, average marker distance 0.34 cM. high degree collinearity between physical observed.

Abstract Plant resistance inducers represent an alternative strategy that mitigate stress-induced damage in plants. Previously, 2-amino-3-methylhexanoic acid (AMHA), a novel natural plant inducer, was shown to significantly bolster cold tolerance, thermotolerance, and pathogen However, the intricate mechanisms underlying AMHA’s response stress remain elusive. Thus, we investigated physiological transcriptomic analyses of AMHA pretreatment on tea determine its substantial role under stress. The results showed with 100 nM effectively mitigated detrimental effects photosynthesis growth. Furthermore, differentially expressed genes were identified through RNA-seq during pretreatment, stress, 2 days recovery. These mainly enriched pathways related flavonoid/anthocyanin, carotenoid, ascorbic acid-glutathione (AsA-GSH) cycle, including GST (encoding glutathione S-transferase). Potential regulatory relationships between transcription factors also established. Antisense oligodeoxynucleotide-silencing overexpression experiments revealed CsGSTU7 enhances by maintaining redox homeostasis. In conclusion, our study suggests antioxidant-related signaling molecules play critical cascades transcriptional regulation mediating AMHA-induced cold-stress plant.
