Background: As an important economic crop, the development of floral organs in tea plants plays an essential role in tea yield, quality, and varietal improvement. Previous studies have shown significant downregulation of the CsSTK gene in the pistil-deficient mutant 'Yuncha Qirui' (CRQS) during flower development, suggesting its involvement in floral organ and pistil development.
Results: This study investigated CsSTK function and regulatory mechanisms, concurrently conducting a systematic identification of the BPC transcription factor family members in tea plants.

The tea plant (Camellia sinensis) is a vital economic crop whose quality and health benefits are primarily determined by flavonoid compounds, particularly catechins and anthocyanins. However, the dynamic regulatory mechanisms of governing flavonoid accumulation remain unclear. A novel tea germplasm, MHLC, with a reddish-purple phenotype was identified in this study.

However, the shifting pattern of secondary metabolites between scions, rootstocks, and non-grafted tea leaves is unclear. We employed "Yuncha 1" as the scion and "Zijuan" as the rootstock with significant differences in leaf color traits to reveal the influences of grafting on the generation of secondary metabolites and transcriptional activities.

Cadmium (Cd) is a widely used heavy metal and has recently been recognized as a possible source of human toxicity due to its ability to accumulate in organs. Accumulation of heavy metals has several adverse effects, including inducing inflammation, in multiple organs, such as the testis. However, how Cd ions are sensed by host cells and how tissue inflammation eventually occurs remains unclear.

is a tea leaf moth that is considered one of the most destructive pests of (tea plant). Several recent studies have shown that many insects acquire part of the microbiome from their host and soil, but the pattern and diversity of their microbiome have not been clearly demonstrated. The present study aimed to investigate the bacterial and fungal communities present in the rhizospheric soil and leaf of tea plant compared to the gut of tea moth at different developmental stages (larvae, pupae, adult female and male) using Illumina MiSeq technology.

Mitochondrial biogenesis is the process of generating new mitochondria to maintain cellular homeostasis. Here, we report that viruses exploit mitochondrial biogenesis to antagonize innate antiviral immunity. We found that nuclear respiratory factor-1 (NRF1), a vital transcriptional factor involved in nuclear-mitochondrial interactions, is essential for RNA (VSV) or DNA (HSV-1) virus-induced mitochondrial biogenesis.

Excessive dietary uptake of saturated fatty acids (SFAs) causes mitochondrial dysfunction and metabolic disorders, while unsaturated fatty acids (UFAs) counterbalance these detrimental effects. It remains elusive how SFAs and UFAs differentially signal toward mitochondria for mitochondrial performance.

ATG9A is a highly conserved membrane protein required for autophagy initiation. It is trafficked from the trans-Golgi network (TGN) to the phagophore to act as a membrane source for autophagosome expansion. Here, we show that ATG9A is not just a passenger protein in the TGN but rather works in concert with GRASP55, a stacking factor for Golgi structure, to organize Golgi dynamics and integrity.

Albino tea plants generally have higher theanine, which causes their tea leaves to taste fresher, and they are an important mutant for the breeding of tea plant varieties. Earlier, we reported an albino germplasm, 'Menghai Huangye' (MHHY), from Yunnan Province and found that it has a lower chlorophyll content during the yellowing stage, but the mechanism underlying low chlorophyll and the yellowing phenotype is still unclear. In this study, the pigment contents of MHHY_May (yellowing, low chlorophyll), MHHY_July (regreening, normal chlorophyll), and YK10_May (green leaves, normal chlorophyll) were determined, and the results showed that the lower chlorophyll content might be an important reason for the formation of the yellowing phenotype of MHHY.
