Special Issue Information

Dear Colleagues,

Tea is one of the most popular beverages in the world. Tea consumption is steadily increasing due to its healthy effects, especially while the world faces the COVID-19 epidemic. Tea also plays a significant role in terms of employment and income for millions of poor farmers. With the consumption of high-quality tea, tea producers are facing enormous problems, such as climate change, lack of labor and the high cost of agricultural inputs, tea cultivation and management needs to address these challenges. At the same time, advanced technologies such as genomics, proteomics and metabonomics, new agri-input and machines and new management models, e.g., carbon-neutral tea production, are involved to achieve better quality, higher efficiency and more environmental friendly tea production.

In this research topic, we are focusing on the latest research in the cultivation and management of tea trees. We particularly welcome contributions that include, but not are limited to, the following topics:

  • Tea plant physiology and biochemistry;
  • Tea plant nutrition and fertilization;
  • Soil physics, chemistry and biochemistry;
  • Pests, diseases, weeds and their management;
  • Climate change and its mitigation and adaption;
  • Inter planting and other micro-climate management;
  • Interaction of tea plant with the environment;
  • Organic and low carbon tea production;
  • Other field operations and management for tea cultivation.

Tea is one of the most popular non-alcoholic beverages globally. The leaves of the tea plants serve as the raw materials for tea production, making tea tree cultivation widespread as an economically significant tree species. Nonexpressor of pathogenesis-related genes 1 (NPR1) is a key regulator of the salicylic acid (SA) signaling pathway, playing a significant role in the plant’s response to biotic and abiotic stresses. However, the NPR1-like gene family in tea plants remains elusive. This study aims to systematically analyze the NPR1-like gene family in tea plants. Four CsNPR1-like genes were identified and categorized into three branches based on phylogenetic analysis. Collinearity analysis demonstrated conservation of the NPR1-like gene across different species. Analysis of cis-regulatory elements suggested that CsNPR1-like genes may be involved in various hormonal and stress responses. Protein structure analysis revealed that the CsNPR1-likes exhibited typical ANK and BTB/POZ structural domains. The protein interaction network identified various known and novel NPR1-interacting proteins, including the TGA transcription factor, which was further confirmed in planta. Meta-analysis of transcriptome data indicated that CsNPR1-like genes had spatiotemporal expression patterns and were induced by drought and cold stresses. Additionally, CsNPR1a activates the accumulation of the acidic SA-dependent pathogenic-associated protein PR1 but not the basic chitinase (PR3) in a transient expression assay. This study provides comprehensive information for investigating the NPR1-like gene family in tea plants. Full article

Flavanols are known as the most important antioxidants in tea (Camellia sinensis), but their contribution to the antioxidant capacity across tea cultivars has not been quantified. This study explored whether the variations of antioxidant capacity across tea cultivars could be linked to variations in main flavanol concentrations using 20 widely planted Chinese tea cultivars. The results showed that concentrations of flavanols, both monomeric (total catechins; 3.77%–8.85% d.w.) and polymeric forms (condensed tannins; 9.48%–17.67% d.w.), varied largely across tea cultivars. The contribution of total catechins to the antioxidant capacity in tea (R2 = 0.54–0.55) was greater than that of condensed tannins (R2 = 0.35–0.36) and total phenolic concentrations (R2 = 0.33–0.36). Individual catechin components collectively explained 54.94%–56.03% of the variations in antioxidant capacity across tea cultivars. Epigallocatechin gallate (EGCG) was the leading catechin component that determined the antioxidant capacity in tea (p < 0.001), accounting for up to 57% of the differences in catechin composition between tea cultivars with high and low antioxidant capacities. These results suggested that flavanols were stronger predictors of the antioxidant capacity across tea cultivars compared to total phenolic concentrations, providing guidance for breeding tea cultivars with strong antioxidant capacities.
