Summary: In this study, a total of 20 ASMT genes were identified in tea plants and classified into three subfamilies. These genes were unevenly distributed on seven chromosomes, with two pairs of genes showing fragment duplication. Gene sequence analysis showed that the structures of the ASMT genes in tea plants were highly conserved, with slight differences in gene structures and motif distributions among different subfamily members. Transcriptome analysis revealed that most CsASMT genes did not respond to drought and cold stresses, while CsASMT08, CsASMT09, CsASMT10, and CsASMT20 significantly responded to these stresses. CsASMT08 and CsASMT10 were highly expressed under low-temperature stress and negatively regulated in response to drought stress. Combined analysis indicated that CsASMT08 and CsASMT10 were potential regulators of abiotic stress resistance in tea plants. These findings provide insights into the functional properties of CsASMT genes in melatonin synthesis and abiotic stress in tea plants.

Summary: In this study, 56 CsHIPP genes were systematically identified in the tea plant, and their expression patterns in different tissues and Cd-treated roots were investigated. Three CsHIPP genes with high expression levels in Cd-treated roots were selected as candidate genes associated with Cd tolerance. Overexpression of these three genes in a yeast mutant rescued Cd-sensitive yeast and increased yeast resistance to Cd stress, suggesting their involvement in Cd tolerance. These findings improve our understanding of the Cd absorption and detoxification mechanisms in tea plants.

Summary: Excessive intake of high-caffeine tea poses health risks, so cultivating tea cultivars with less caffeine is a viable solution. Cocoa tea, a wild tea plant with low or no caffeine, is difficult to propagate using traditional methods. This study investigated the variation in caffeine and other chemical compositions in seed-propagated cocoa tea plants, finding significant differences in chemical composition and suggesting that natural seed-propagated cocoa tea seedlings are not suitable for producing low-caffeine tea. However, these seedlings have high levels of GCG, a stable antioxidant, making them a good source for extracting antioxidants.

Summary: In this study, the characteristics and functions of the P450 gene family in Camellia sinensis were analyzed using bioinformatics-based methods. A total of 273 putative P450 genes were identified, and they were well-balanced across the genome. Phylogenetic analysis divided the CsP450s into 34 subfamilies, with CYP71 being the most abundant. Subcellular localization analysis showed that P450 was distributed in various organelles. The promoter region of CsP450s contained cis-acting elements related to phytohormones and stress responses. Tissue expression analysis revealed that P450 was highly expressed in roots and stems. Furthermore, qPCR analysis confirmed the expression patterns under drought and cold stress.

Summary: In this study, a comprehensive identification and analysis of GSTs in tea plant were conducted, and their important roles in plant growth, development, and stress responses were revealed. The study found that CsGSTs were unevenly distributed across the tea plant genome and tandem duplication was the main driving force for their expansion. Furthermore, CsGSTs were found to respond to multiple stresses and exhibit different expression patterns in different tissues. CsGSTU19, localized in the nucleus and cell membrane, was proven to be involved in tea plant defense against temperature stresses and Co. camelliae infection.

Summary: A SYBR Green real-time quantitative polymerase chain reaction (RT-qPCR) method was developed to detect four virus segments of Tea plant necrotic ring blotch virus (TPNRBV). The study found that mature leaves contained the highest viral load, while the concentrations of the virus in other tissues decreased with increasing distances from symptomatic leaves. TPNRBV did not efficiently spread through seeds, cuttings, or mechanical inoculation, but was transmitted to some tea cultivars under field conditions.

Summary: Cold stress is a significant environmental factor that negatively affects tea plant growth and productivity. The application of exogenous ascorbic acid improves the cold tolerance of tea plants by reducing lipid peroxidation and enhancing photosynthetic efficiency. Transcriptome analysis reveals that ascorbic acid treatment modulates the expression of cell wall remodeling-related genes. These findings suggest that ascorbic acid maintains ROS homeostasis by down-regulating the ROS-scavenging system and exerts protective effects through cell wall remodeling. Ascorbic acid can be used as a potential approach to enhance the cold tolerance of tea plants without pesticide residual concerns.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
