An upgrade synthesis method of electroless copper plating was developed to prepare the copper-coated mesophasepitch-based carbon fibers (Cu@CF) with APTES (3-Aminopropyl triethoxysilane) grafting modification. The microstructureand properties of the fibers which were prepared by the APTES sensitization method were investigated and compared withthose prepared by the conventional SnCl2 sensitization method. The results showed that as-coated fibers sensitized by APTESdemonstrated to have better interfacial cohesion between the copper layer and the fiber surface than those sensitized by SnCl2did. Moreover, the resistivity of Cu@CF-APTES declined to 2.3±0.9 μΩ·cm, while that of Cu@CF-SnCl2 was 9.3±3.7μΩ·cm. Besides, not only the strength of Cu@CF-APTES increased, but the strength discreteness of them reduced due to thefact that no peeling phenomenon was observed between the copper layer and fiber during the stretch test.

The WRKY transcription factors (TFs) family is one of the largest TF families in plants and plays a central role in diverse regulation and multiple stress responses. However, the systematical analysis of the WRKY gene family in tea plant (Camellia sinensis) based on genomic data has been lacking. The primary objective of this study was to set a systematic analysis of the WRKY gene family based on genomic data in tea plant and analyze their expression profiles under various abiotic stresses. We searched the tea plant genome using the consensus model of the WRKY domain (PF03106) and then used these search results to identify all the WRKY family members by SMART and the CDD program. Analyze their phylogeny, classification, structure, conserved motifs, Cis-elements, interactors and expression profiles. 56 putative WRKY genes were identified from the tea plant genome and divided into three main groups (I–III) and five subgroups (IIa–IIe) according to the WRKY domains and the zinc-finger structure. The gene structure and conserved motifs of the CsWRKY genes were also characterized and were consistent with the classification results. Annotation analysis showed that 34 CsWRKY genes may be involved in stress responses. Promoter analysis implied that CsWRKY genes, except for CsWRKY55, possessed at least one abiotic stress response cis-element. Expression profiles of CsWRKY genes in different tissues were analyzed with RNA-seq data. The results showed that 56 CsWRKY genes had differential expression in their transcript abundance. The expression profiles also showed that many identified CsWRKY genes were possibly involved in the response to cold, drought, salt, or ABA treatment. Tea plant genome contains at least 56 WRKY genes. These results provide useful information for further exploring the function and regulatory mechanism of CsWRKY genes in the growth, development, and adaption to abiotic stresses in tea plant.
