Summary: Camellia sinensis is the source of various teas consumed globally, which are classified based on the oxidation of their bioactive compounds. These compounds, such as methyl-xanthines, amino acids, and flavan-3-ols, contribute to the taste and health properties of teas, with recognized antioxidant, anti-cancer, and anti-inflammatory benefits. New approaches have been developed to preserve these bioactive compounds given their susceptibility to oxidation during processing and digestion.

Summary: In this study, metabolomic and transcriptomic analyses were conducted to investigate the differences in accumulation and regulation of flavonoids and caffeine in different Chinese tea varieties. It was found that the 'MYC' group had lower levels of caffeine accumulation, with the deficiency in expression of the TCS1 gene being the key factor. This research provides insights into the metabolite accumulation characteristics and regulatory networks, serving as a reference for the selection and breeding of tea varieties.

Summary: This study investigated how light intensity regulates catechins biosynthesis in tea plants. Results showed that moderate to high light intensity increased catechin content and photosynthetic capacity, while extremely low or high light intensity decreased them. The biosynthesis of catechins in tea plants was found to be mediated by the plant's photosynthetic capacity.

Summary: Tea plants, known for their long cultivation history, have a complex genetic background due to self-incompatibility and extensive hybridization. Molecular markers have been instrumental in understanding the tea germplasm resources, including the origin, preservation, and identification, as well as breeding of excellent cultivars of tea plants. However, existing information on molecular markers in tea plants is scattered, making it challenging to grasp the advancements. This paper provides a comprehensive summary of the development and types of molecular markers, their application in tea plants, and offers perspectives for future research.

Summary: High temperatures negatively affect the flavonoid content of tea leaves, and two transcription factors, CsHSFA1b and CsHSFA2, are activated and regulate flavonoid biosynthesis during heat treatment. CsHSFA1b and CsHSFA2 directly activate CsJAZ6 expression and suppress the jasmonate pathway. These findings suggest a valuable candidate pathway for breeding and cultivating heat-resistant tea.

Summary: The study investigated the genetic diversity and admixture of Diospyros germplasm in the Western Caucasus, revealing genetic clusters in Diospyros species and admixture in D. kaki genotypes. Phenotypical traits in D. kaki collection corresponded with genetic data, with frost tolerant genotypes showing high levels of admixture with D. virginiana. Low genetic diversity between distant D. lotus populations suggests a single introduction source to the Western Caucasus.

Summary: This study evaluated the efficiency of 36 new SCoT markers, 10 new ISSR markers, and 5 microsatellites in characterizing genetic diversity in a chrysanthemum core collection of 95 accessions. Several new SCoT and ISSR markers were found to be effective for genetic diversity analysis. Results from STRUCTURE analysis revealed genetic admixtures in Russian cultivars, while neighbor joining analysis showed the best accordance with phenotype and origin. Additionally, specific SCoT markers were suitable for distinguishing groups based on phenotypical traits.

Summary: This study aimed to evaluate the effects of calcium on the tea plant's response to drought. The results showed that calcium application can reduce membrane damage and increase cell sap pH in tea plants under drought stress. Calcium also enhances the accumulation of certain amino acids and cations. Additionally, calcium affects galactinol metabolism and participates in the regulation of stomatal aperture.

Summary: Tea, a widely consumed and planted beverage worldwide, has significant economic, health, and cultural values. Cold stress can greatly affect tea yields and quality, but tea plants have evolved physiological and molecular mechanisms to cope with this stress. Understanding how tea plants perceive and respond to cold stress is crucial for breeding new varieties with improved quality and stress resistance.

Summary: In this study, the transcriptional responses of tea plants to long-term cold, freezing, and drought were analyzed using RNA-seq and genome resequencing. The highest number of DEGs were identified under long-term cold and freezing, while the lowest number were observed under 3-day and 9-day drought. The recovery after cold stress had a significantly higher number of DEGs compared to drought recovery. Only a small portion of cold-induced genes were upregulated by drought. A total of 1,492 transcription factor genes related to 57 families were identified, with only 20 commonly upregulated by all three stresses.
