Project description:MicroRNAs (miRNAs) are a type of small non-coding RNAs, which play important roles in plant growth, development and stress responses. Tea (Camellia sinensis) prepared from tea tree is the oldest and most popular nonalcoholic beverages in the world, and has large economic, medicinal and cultural significance. Nevertheless, there are a few studies on the miRNAs and their functions in Camellia sinensis. We sequenced 9 small RNA libraries and 9 RNA-Seq libraries from roots, leaves and flowers tissues. Through comprehensive computational analyses of 9 small RNA profiles, we identified 200 conserved miRNAs of which 138 have not been reported, and 56 novel miRNAs with 33 have not been reported. Nearly, two thousands genes have significantly different expression levels in tissues. In order to identify targets of miRNAs, we sequenced two degradome profiles from leaves and roots, respectively. Totally, more than 3,000 putative targets of conserved miRNAs were identified in both degradome profiles by using the SeqTar algorithm. These results clearly enhanced our understanding about small RNA guided gene regulations in Camellia sinensis.

Project description:Basic region/leucine zipper (bZIP) transcription factors play vital roles in the abiotic stress response of plants. However, little is known about the function of bZIP genes in Camellia sinensis. Here, we show that CsbZIP6 is induced during cold acclimation in tea plant. Constitutive overexpression of CsbZIP6 in Arabidopsis lowered the plants’ tolerance to freezing stress and ABA exposure during seedling growth. Compared to wildtype (WT) plants, CsbZIP6 overexpression (OE) lines exhibited increased levels of electrolyte leakage (EL) and malondialdehyde (MDA) contents and reduced levels of total soluble sugars (TSS) under cold stress conditions. Microarray analysis of transgenic Arabidopsis revealed that many differentially expressed genes (DEGs) between OE lines and WT plants could be mapped to ‘response to cold’ and ‘response to water deprivation’ terms based on GO analysis. Interestingly, CsbZIP6 overexpression repressed most of the cold- and drought-responsive genes as well as the starch metabolism under cold stress conditions. Taken together, our data suggests that CsbZIP6 functions as a negative regulator of the cold stress response in Arabidopsis thaliana, potentially by down-regulating cold-responsive genes. To obtain insights into the molecular mechanisms by which CsbZIP6 mediates senstivity to cold stress in Arabidopsis plants, gene expression profiles in leaves of two CsbZIP6 OE lines and WT plants under normal (22ºC) and cold (4ºC) conditions were compared. The Agilent Arabidopsis Gene Expression (4×44K, Design ID: 021169) was used in this experiment.

Project description:Leaf colour variation is observed in several plants. We obtained two types of branches with yellow (H1) and variegated (H2) leaves from Camellia sinensis. To reveal the mechanisms that underlie the leaf colour variations, proteomic analysis using label-free MS-based approach was performed using leaves from variants and normal branches (CKs).

Project description:Tea (Camellia sinensis (L.) O. Kuntze) is an important non-alcoholic commercial beverage crop. Tea tree is a perennial plant, and winter dormancy is its part of biological adaptation to environmental changes. We recently discovered a novel tea tree cultivar that can generate tender shoots in winter, but the regulatory mechanism of this ever-growing tender shoot development in winter is not clear. In this study, we conducted a proteomic analysis for identification of key genes and proteins differentially expressed between the winter and spring tender shoots, to explore the putative regulatory mechanisms and physiological basis of its ever-growing character during winter.
