Project description:Solexa sequencing technology was used to perform high throughput sequencing of the small RNA library from the cold treatment of tea leaves. Subsequently, aligning these sequencing date with plant known miRNAs, we characterized 112 C. sinensis conserved miRNAs. In addition, 215 potential candidate miRNAs were found; among them, 131 candidates with star sequence were chosen as novel miRNAs. There are both congruously and differently regulated miRNAs, and line-specific miRNAs were identified by microarray-based hybridization in response to cold stress. The miRNA chip included 3228 miRNA probes corresponding to miRNA transcripts listed in Sanger miRBase release 19.0 and 283 novel miRNAs probes founding in tea plant. In the study presented here, two tea plant cultivars, ‘Yingshuang’ (YS, a cold-tolerant tea plant cultivar) and ‘Baiye 1’ (BY, a cold-sensitive tea plant cultivar), were kept at 4°C for 4,12, 24 h, respectively, and 28°C for as control. These samples were used to acquire expression profiles of a total of 3,511 unique genes, leading to the successful construction of supervised

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: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.

Project description:Background: Lysine crotonylation (Kcr), as a novel evolutionarily conserved type of PTM, is ubiquitous and essential in cell biology. However, its functions in tea plant, an important beverage crop, are largely unknown. Our study firstly attempted to describe Kcr proteins in tea leaves under NH4+ deficiency/resupply, and provided significant insights into exploring the physiological role of Kcr in plants for N utilization. Results: We performed the global analysis of crotonylome in tea plants under NH4+ deficiency/resupply using high-resolution LC-MS/MS coupled with highly sensitive immune-antibody. A total of 2288 kcr sites on 971 proteins were identified, of which contained in 15 types of Kcr motifs. Most of Kcr proteins were located in chloroplast and cytoplasm. 120 and 151 Kcr proteins were significantly changed at 3 hours and 3days of NH4+ resupply, respectively. Bioinformatics analysis showed that differentially expressed Kcr proteins participated in diverse biological processes such as photosynthesis, carbon fixation and amino acid metabolism, suggesting Kcr plays important roles in these processes. Interestingly, a large number of enzymes were crotonylated, and the activity and Kcr level of these enzymes changed significantly after NH4+ resupply, indicating a potential function of Kcr in the regulation of enzyme activities. Moreover, the protein-protein interaction analysis revealed that the diverse interactions of identified Kcr proteins mainly involved in photosynthesis, carbon fixation, amino acid metabolism and ribosome. Conclusions: The results suggested that lysine crotonylated proteins might play regulating roles in metabolic process in tea leaves under NH4+ deficiency/resupply. The critical regulatory roles mainly involved in diverse aspects of primary metabolic processes, especially in photosynthesis, carbon fixation and amino acid metabolism. The provided data may serve as important resources for exploring the physiological, biochemical, and genetic role of lysine crotonylation in tea plants.
