Summary: In this study, tea leaf-color mutants were studied using transcriptome and biochemical analysis, and it was found that the reduced chlorophyll content might be caused by the activation of genes related to chlorophyll degradation, along with a reduction in flavonoid biosynthesis and an accumulation of glutamate. These findings provide new insights into the molecular mechanisms underlying leaf-color bud mutation in tea plants.

Summary: Recently, there has been increased attention on the purple tea cultivars with unique purple-colored leaves. These cultivars are enriched with anthocyanin, which provides a new perspective for studying the metabolic flux of flavonoids in tea plants. This review aims to summarize the latest progress on the composition and accumulation of anthocyanins in tea plants, with discussions on the regulation mechanism and a proposed hypothetical model for leaf color transformation during growth. Novel insights presented in this review will facilitate future in-depth studies of purple tea, providing a theoretical basis for targeted breeding programs in leaf color.

Summary: Seasonal greening is an important survival strategy for albino tea cultivars, and CsRVE1 is identified as a nuclear-located Myb-like transcription factor that can positively modulate this process by activating genes involved in light harvesting and chlorophyll biosynthesis. CsRVE1 directly binds to the promoters of these genes and leads to chlorophyll accumulation in tea leaves. The suppression of CsRVE1 decreases the expression of target genes, while its overexpression increases chlorophyll levels and activates related genes in Arabidopsis.

Summary: Grafting has a significant impact on tea plant cultivation, affecting the growth and quality of tea plants. In this study, it was found that grafting with Yinghong9 as the rootstock increased the content of flavonoids and catechins, while decreasing the total free amino acids in the grafted leaves. Metabolomic and transcriptomic analysis revealed the molecular mechanisms of metabolic regulation, showing upregulation of genes involved in flavonoid biosynthesis and downregulation of amino acid metabolism genes.

Summary: A series of Re modified NiMo/Al2O3 hydrodesulfurization (HDS) catalysts with different contents of Re2O7 were synthesized using stepwise impregnation and co-impregnation methods. The effects of Re modification and impregnation methods on the catalysts' physical-chemical properties were characterized. The results revealed that Re modification improved the crystal morphologies, pore structures, and acid sites of the catalysts. Furthermore, the HDS evaluation showed that Re modification effectively enhanced the conversions, route selectivity, and even selectivity towards 3,3'-DMCHB of 4,6DMDBT, with the stepwise impregnation method exhibiting a more significant effect compared to co-impregnation.

Summary: Cloud services relying on communication, computing, and caching resources are supported by datacenter networks (DCNs). The security of these services is under threat due to the emergence of quantum computers. Quantum key distribution (QKD) technology offers information-theoretically secure secret key sharing between remote users. A quantum cloud, achieved through QKD-secured cloud datacenter networks, provides communication, computing, caching, and cipher resources for data transmission, processing, storing, and encryption. To address the coordination problem of the newly emerged 4C resources, a 4C-oriented control architecture is designed, and innovative heuristic algorithms for securing service function chains are proposed. Simulation results demonstrate that the proposed algorithms outperform the baseline in terms of service success ratio.

Summary: In this paper, the relationships between some vertex-degree-based topological indices (including the general Randic index, the first Zagreb index, and the forgotten index) and the energy of graphs are established by using the concept of the energy of a vertex. Bounds on the energy of graphs containing no isolated vertices are given in terms of the first Zagreb index and the forgotten index. Furthermore, bounds on the normalized Laplacian energy in terms of two particular cases of the general Randic index are obtained.

Summary: Chemical approaches play a crucial role in the design, synthesis, control and engineering of small molecules, polymers and networks, combining covalent bonds and non-covalent interactions to establish complex structures for specific functions. Covalent organic frameworks (COFs) are crystalline porous polymers that integrate organic units into highly ordered structures through polymerization using covalent bonds for primary order structures and non-covalent interactions for high order structures in a one-pot reaction system. This Primer provides a comprehensive overview of the field of COFs, covering chemistry, physics, materials and applications, aiming to present a concise yet complete picture of the field and addressing key fundamental issues with future directions in mind.
