“…Different pruning processes also affect the quality of tea leaves, and in Yunnan tea plantations, metabolite data from the unpruned tea (UPTT) revealed that levels of amino acids leading to sweetness increased, while levels of bitter and astringent catechins and caffeine decreased [ 181 ]. The plant-growth regulator treatment of tea guava tissues located in cell suspension system subserved the accumulation of tea polyphenols and offered support for application in practical tea garden cultivation [ 182 ]. Variable degrees of shade treatment also altered the quality of the tea leaves, with tea plants cultivated under shade not only having elevated theanine and caffeine content and reduced polyphenol content affecting taste, but also stimulating the biosynthesis and transport of theanine at diverse sites [ 183 , 184 ].…”

Tea plants are an economically important crop and conducting research on tea breeding contributes to enhancing the yield and quality of tea leaves as well as breeding traits that satisfy the requirements of the public. This study reviews the current status of tea plants germplasm resources and their utilization, which has provided genetic material for the application of multi-omics, including genomics and transcriptomics in breeding. Various molecular markers for breeding were designed based on multi-omics, and available approaches in the direction of high yield, quality and resistance in tea plants breeding are proposed. Additionally, future breeding of tea plants based on single-cellomics, pangenomics, plant–microbe interactions and epigenetics are proposed and provided as references. This study aims to provide inspiration and guidance for advancing the development of genetic breeding in tea plants, as well as providing implications for breeding research in other crops.
