Project description:An increasing amount of evidence attest that the tea made by albino tea cultivars processes characteristic aroma and taste, which has been considered as a new potential product in the market. Therefore, flavor formation mechanism of albino tea cultivars have drawn exceeding attention from researchers. In this study, transcriptome, metabolomics, and whole-genome bisulfite sequencing (WGBS) were employed to investigate shading effects on leaf color conversion and biosynthesis of three major secondary metabolites in the Albino tea cultivar ‘Yujinxiang’. The increase of leaf chlorophyll level is the major cause of shaded leaf greening from young pale or yellow leaf. Transcriptome analysis showed differentially expressed genes (DEGs) mainly participated in biosynthesis of amino acids, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, sulfur metabolism, purine metabolism, and pentose and glucuronate interconversions in shading period compared with control group. The result of metabolomics indicated the total catechins level of shading group was significantly decreased than the control; however, the abundance of caffeine was markedly increased, and theanine level was nearly not influenced. Whole-genome DNA methylation analysis revealed that the global genomic DNA methylation patterns of shading period were remarkably altered compared with the control. Furthermore, differentially methylated regions (DMRs) and the DMR-related DEGs between shading and non-shading analysis indicated the DMR-related DEGs were the critical participants in biosynthesis of three major secondary metabolites. To sum up, these findings suggested that the altered levels of DNA methylation may be the main cause for biosynthesis changes of three major secondary metabolites in ‘Yujinxiang’.

Project description:BACKGROUND: Evaluation of the airway transcriptome may reveal patterns of gene expression that are associated with clinical phenotypes of asthma. To define transcriptomic endotypes of asthma (TEA) we analyzed gene expression in induced sputum that correlate with phenotypes of disease. METHODS: Gene expression was measured in sputum of subjects with asthma using Affymetrix HuGene ST 1.0 microarrays. Unsupervised clustering analysis of genes in pathways selected from the Kyoto Encyclopedia of Genes and Genomes (KEGG) identified TEA clusters. Clinical characteristics were compared and logistic regression analysis of matched blood samples defined an expression profile to determine the TEA cluster assignment in a cohort of children with asthma for validation. RESULTS: Three TEA clusters were identified. TEA cluster 1 had the most subjects with a history of intubation (P = 0.05), a lower pre-bronchodilator FEV1 (P = 0.006), a higher bronchodilator response (P = 0.03), and higher exhaled nitric oxide levels (P = 0.04), compared to the other TEA clusters. TEA cluster 2, the smallest cluster had the most subjects that were hospitalized for asthma (P = 0.04). Subjects in TEA cluster 3, the largest cluster, had normal lung function, low exhaled nitric oxide levels, and lower inhaled steroid requirements. Evaluation of TEA clusters in children confirmed that TEA clusters 1 and 2 are associated with a history of intubation (P = 5.58 x 10-06) and hospitalization (P = 0.01), respectively. CONCLUSIONS: Patterns of gene expression in the sputum and blood reveal TEA clusters that are associated with severe asthma phenotypes in children and adults. Gene expression was measured in sputum of subjects with asthma using Affymetrix HuGene ST 1.0 microarrays. Unsupervised clustering analysis of genes in pathways selected from the Kyoto Encyclopedia of Genes and Genomes (KEGG) identified TEA clusters. Clinical characteristics were compared and logistic regression analysis of matched blood samples defined an expression profile to determine the TEA cluster assignment in a cohort of children with asthma for validation.

Project description:In field conditions, tea plants are often exposed to drought stress, which has profound effects on the growth and development of tea plants. However, most studies on tea plants in response to drought stress focused on single gene or protein expression, and transcriptome or proteome profiles, the impact of drought stress on ubiquitination in proteins remains unearthed. We performed a global profile of ubiquitinated (Kub) proteins in tea leaves under drought stress. In total, 1,409 lysine Kub sites in 781 proteins were identified, of which 14 sites in 12 proteins were up-regulated and 123 sites in 91 proteins were down-regulated compared with drought and control. Furthermore, we analyzed the Kub proteins related to ubiquitin-mediated proteolysis, catechins biosynthesis, and carbohydrate and amino acid metabolism in tea leaves under drought stress. The results indicated that many Kub proteins involved in ubiquitin-mediated proteolysis played important roles in protein degradation. Several Kub proteins related to catechins biosynthesis were positively correlated with each other because of their co-expression and co-localization. Our study preliminarily revealed the global profiling of Kub proteins in metabolic pathways and provided an important resource for further study on the functions of Kub proteins in tea plants under drought stress.

Project description:The tea plant (Camellia sinensis (L.) O. Kuntze) is often commercially used as a source of non-alcoholic beverages and is an economically important woody crop (Chen et al., 2007). As living standards have improved, the requirement for high-quality life has increased in modern society. ‘Anji Baicha’ (alias ‘Baiye 1’ or ‘White Leaf 1’) is an excellent tea cultivar with albino phenotype and it is popular in producing high-quality green tea. The traits of ‘Anji Baicha’ are as follows. Young ‘Anji Baicha’ shoots are yellow-green when the early spring temperature is below 20°C. As the leaves fully expand, the leaves become white. The leaves gradually return to green when the environmental temperature increases (Cheng et al., 1999; Li et al., 2002, 2011). Previous reports have suggested a positive correlation between amino acid concentration and albinism as well as a negative correlation between tea polyphenols and albinism (Li et al., 1996; Du et al., 2006; Xiong et al., 2013). Therefore, the quality of ‘Anji Baicha’ is much higher when new shoots become albino due to their rich amino acid content and modest tea polyphenol content. Plants adjust their metabolism in response to environmental stimuli to eventually bring about changes in protein activities and levels, and this adaptive process includes posttranslational protein modifications (PTMs) (Prabakaran et al., 2012). PTMs have been reported to regulate various processes, including DNA interaction, protein-protein interactions, enzyme activation and protein stability. Among the hundreds of different PTMs, lysine acetylation is an abundant, reversible and highly regulated PTM (Zhang et al., 2009; Wu et al., 2011).
