Transcriptome sequencing of fresh leaves from grafted tea plants
This study investigates how rootstock genotype influences secondary metabolism in grafted tea plants (Camellia sinensis). Using a high-aroma Oolong tea model system (hetero-grafting vs. homo-grafting), we performed transcriptome sequencing to elucidate the molecular basis of a rootstock-driven metabolic trade-off between phenylpropanoids (taste compounds) and terpenoids (aroma compounds). The dataset reveals systemic transcriptional reprogramming of key biosynthetic pathways, providing insights into grafting-mediated flavor regulation and offering candidate genes for precision quality improvement in perennial crops.
