Abstract Background Tea is the most popular non-alcoholic health beverage in world. The tea plant ( Camellia sinensis (L.) O. Kuntze) needs to undergo a cold acclimation process enhance its freezing tolerance winter. Changes that occur at molecular level response low temperatures are poorly understood plants. To elucidate mechanisms of acclimation, we employed RNA-Seq and digital gene expression (DGE) technologies study genome-wide profiles during Results Using Illumina sequencing platform,...
Abstract Tea is an economically important plant characterized by a large genome, high heterozygosity, and species diversity. In this study, we assemble 3.26-Gb high-quality chromosome-scale genome for the ‘Longjing 43’ cultivar of Camellia sinensis var. . Genomic resequencing 139 tea accessions from around world used to investigate evolution phylogenetic relationships accessions. We find that hybridization has increased heterozygosity wide-ranging gene flow among populations with spread...
The branching angle of tea plants is a key factor in determining their structure, which significantly affects yield, suitability for mechanical harvesting, and overall plant architecture. However, the mechanisms underlying formation remain unclear. In this study, we explored mechanism by analysing transcriptome hormone levels cultivars with different angles. results indicated that gibberellin positively regulates plants, cytokinins, auxin, abscisic acid involved angles plants. analysis...
Major secondary metabolites, including flavonoids, caffeine, and theanine, are important components of tea products closely related to the taste, flavor, health benefits tea. Secondary metabolite biosynthesis in Camellia sinensis is differentially regulated different tissues during growth development. Until now, little was known about expression patterns genes involved metabolic pathways or their regulatory mechanisms. This study aimed generate profiles for C. build a gene regulation model...
Reliable reference selection for the accurate quantification of gene expression under various experimental conditions is a crucial step in qRT-PCR normalization. To date, only few housekeeping genes have been identified and used as tea plant. The validity those are not clear since their stabilities rigorously examined. identify more appropriate studies on plant, we examined stability 11 candidate from three different sources: orthologs Arabidopsis traditional stably expressed whole-genome...
Anthracnose caused by Colletotrichum is one of the most severe diseases that can afflict Camellia sinensis. However, research on diversity and geographical distribution in China remain limited. In this study, 106 isolates were collected from diseased leaves Ca. sinensis cultivated 15 main tea production provinces China. Multi-locus phylogenetic analysis coupled with morphological identification showed belonged to 11 species, including 6 known species (C. camelliae, C. cliviae, fioriniae,...
The tea plant (Camellia sinensis (L.) O. Kuntze) is one of the most economically important woody crops. Recently, many leaf color genotypes have been developed during breeding and become valuable materials in processing green tea. Although physiological characteristics some mutants plants partially revealed, little known about molecular mechanisms leading to chlorina phenotype plants. yellow-leaf cultivar Zhonghuang 2 (ZH2) was selected breeding. In comparison with Longjing 43 (LJ43), a...
The tumor suppressor PTEN is a putative negative regulator of the phosphatidylinositol 3-kinase/Akt pathway. Exposure to Zn2+ ions induces Akt activation, suggesting that may be modulated in this process. Therefore, effects on were studied human airway epithelial cells and rat lungs. Treatment with resulted significant reduction levels protein dose- time-dependent fashion cell line. This effect Zn2+was also observed normal primary culture epithelium vivo. Concomitantly, mRNA significantly...
Winter dormancy is an important biological feature for tea plant to survive cold winters, and it also affects the economic output of plant, one few woody plants in world whose leaves are harvested non-conifer evergreen species with characterized dormancies. To discover bud regulation mechanism winter, we analyzed global gene expression profiles axillary buds at paradormancy, endodormancy, ecodormancy, flush stages by RNA-Seq analysis. In total, 16,125 differentially expressed genes (DEGs)...
Catechins are the most important bioactive compounds in tea, and have been demonstrated to possess a wide variety of pharmacological activities. To characterize quantitative trait loci (QTLs) for catechins content tender shoots tea plant, we constructed moderately saturated genetic map using 406 simple sequence repeat (SSR) markers, based on pseudo-testcross population 183 individuals derived from an intraspecific cross two Camellia sinensis varieties with diverse composition. The consisted...
Tea plant (Camellia sinensis) is one of the most economically valuable crops in world. Anthracnose can affect growth leaves and cause serious yield losses tea. plants are rich secondary metabolites; however, their roles resistance to anthracnose unclear. Herein we compared contents total phenolics, catechins, caffeine two cultivars with different resistances during Colletotrichum fructicola infection. (-)-Epigallocatechin-3-gallate (EGCG), (+)-catechin (C), caffeine, critical regulatory...
Tea plant breeding is a topic of great economic importance. However, disease remains major cause yield and quality losses. In this study, an anthracnose-resistant cultivar, ZC108, was developed. An infection assay revealed different responses to Colletotrichum sp. between ZC108 its parent cultivar LJ43. had greater resistance than LJ43 camelliae. Additionally, exhibited earlier sprouting in the spring, as well leaf shape architecture. Microarray data that genes are differentially expressed...
Basic region/leucine zipper (bZIP) transcription factors play vital roles in the abiotic stress response of plants. However, little is known about function bZIP genes Camellia sinensis .CsbZIP6 was overexpressed Arabidopsis thaliana . Effects CsbZIP6 overexpression on abscisic acid (ABA) sensitivity, freezing tolerance and expression cold-responsive arabidopsis were studied.CsbZIP6 induced during cold acclimation tea plant. Constitutive lowered plants' to ABA exposure seedling growth....
Green tea has attracted an increasing number of consumers worldwide due to its multiple health benefits. With the increase in global warming, more frequent cold spells spring often cause serious damage green production because young leaves used. We recorded changes climatic conditions during a typical spell and symptoms caused by different cultivars breeding lines. By simulating low temperature under controlled conditions, comparative transcriptome metabolic analyses were performed with...
Anthracnose causes severe losses of tea production in China. Although genes and biological processes involved anthracnose resistance have been reported other plants, the molecular response to plant is unknown. We used susceptible cultivar Longjing 43 resistant Zhongcha 108 as materials compared transcriptome changes leaves both cultivars following Colletotrichum fructicola inoculation. In all, 9015 8624 were differentially expressed between their controls (0 h), respectively. cultivars,...
Abstract Sugars Will Eventually be Exported Transporters (SWEETs) are important in plant biological processes. Expression levels of CsSWEET1a and CsSWEET17 induced by cold acclimation (CA) stress Camellia sinensis. Here, we found that was alternatively spliced, its exclusion (Ex) transcript associated with the CA process. Both plasma membrane-localized transport hexoses, but cytoplasm-localized CsSWEET17-Ex does not. These results indicate alternative splicing may involved regulating...
