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...
To understand tea germplasms better and to use them effectively for production breeding, the catechin content of 403 accessions representative collected from various locations in China were studied using HPLC. The these varied 56.6 231.9 mg/g averaged 154.5 ± 18.1 mg/g. One germplasm with low total (TC) (<60 mg/g) three high TC (>200 contents found. Averages varieties Camellia sinensis (L.) O. Kuntze, namely, sinensis, assamica, pubilimba, 152.9 16.2 mg/g, 162.8 22.3 165.1 21.3 respectively....
The new shoots of the albino tea cultivar 'Anji Baicha' are yellow or white at low temperatures and turn green as environmental increase during early spring. metabolite profiles exhibit considerable variability over three color developmental stages, especially regarding carotenoid, chlorophyll, theanine concentrations. Previous studies focused on physiological characteristics, gene expression differences, variations in abundances plant leaves specific growth stages. However, molecular...
Tea plant (Camellia sinensis) is an economically important beverage crop. Drought stress (DS) seriously limits the growth and development of tea plant, thus affecting crop yield quality. To elucidate molecular mechanisms responding to DS, we performed transcriptomic analysis during three stages [control (CK) recovery (RC) after DS] using RNA sequencing (RNA-Seq). Totally 378.08 million high-quality trimmed reads were obtained assembled into 59,674 unigenes, which extensively annotated. There...
Abstract Free amino acids are one of the main chemical components in tea, and they contribute to pleasant flavor, function, quality notably level theanine. Here, a high-density genetic map was constructed characterize quantitative trait loci (QTLs) for free acid content. A total 2688 polymorphic SNP markers were obtained using genotyping-by-sequencing (GBS) based on 198 individuals derived from pseudotestcross population “Longjing 43” × “Baijiguan”, which elite albino tea cultivars,...
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...
Genetic maps are important tools in plant genomics and breeding. The present study reports the large-scale discovery of single nucleotide polymorphisms (SNPs) for genetic map construction tea plant. We developed a total 6,042 valid SNP markers using specific-locus amplified fragment sequencing (SLAF-seq), subsequently mapped them into previous framework map. final contained 6,448 molecular markers, distributing on fifteen linkage groups corresponding to number chromosomes. length was 3,965...
The effects of blue (BL) and green light (GL) treatment during the dark period were examined in Camellia sinensis as a first step to understanding spectral artificial BL GL on plant secondary metabolism signaling interactions. could induce expression CRY2/3, SPAs, HY5, R2R3-MYBs promote accumulation anthocyanins catechins tea plants. GL, other hand, stimulate several functional substances (e.g., procyanidin B2/B3 l-ascorbate) temper these responses via down-regulation CRY2/3 PHOT2....
Albino tea cultivars are special mutants of plants with white or yellow leaf color. In this study, three albino cultivars, including 'Anji Baicha', 'Huangjinya', and 'Baijiguan', two green 'Longjing 43' 'Fuding Dabaicha', were applied to metabolite profiling by gas chromatography-mass spectrometry ultraperformance liquid spectrometry. Multivariate analyses revealed significantly different phenotypes in leaves among cultivars. The differential metabolite-related pathways included galactose...
The young leaves and shoots of albino tea cultivars are usually characterized as having a yellow or pale color, high amino acid, low catechin. Increasing attention has been paid to in recent years because their generally shows umami reduced astringency. However, the genetic mechanism yellow-leaf variation cultivar not elucidated clearly. In this study, bulked segregant RNA-seq (BSR-seq) was performed on yellow- green-leaf hybrid progenies from leaf color population. A total 359 1134...
'Anji Baicha' is an albino tea cultivar with white shoots at low air temperature and green high in early spring. The metabolite contents the dynamically vary color changes shoot development. To investigate metabolomic variation during albescent re-greening stages, gas chromatography–mass spectrometry combined multivariate analysis were applied to analyze profiles different stages development of leaves. three including yellow-green stage, late as well stage distinguished using principal...
Tea leaf color is not only important from an aesthetics standpoint but also related to tea quality. To investigate the molecular mechanisms that determine color, we examined Camellia sinensis cv. 'Anji Baicha' (an albino cultivar) by tandem mass tag isobaric labeling generate a high-resolution proteome and acetyl-proteome atlas of three developmental stages. We identified total 7637 proteins quantified 6256; these, 3232 were classified as differentially accumulated (DAPs). 3161 lysine...
Understanding the genetic basis of theobromine and caffeine accumulation in tea plant is important due to their contribution flavor. Quantitative trait loci (QTL) analyses were carried out identify variants associated with contents ratio using a pseudo-testcross population derived from an intervarietal cross between two varieties Camellia sinensis. A total 10 QTL controlling content (CAF), (TBR), sum (SCT), caffeine-to-theobromine (CTR) identified over four measurement years. The major CAF,...
Abstract The highly unique zigzag-shaped stem phenotype in tea plants boasts significant ornamental value and is exceptionally rare. To investigate the genetic mechanism behind this trait, we developed BC 1 artificial hybrid populations. Our analysis revealed trait as a qualitative trait. Utilizing whole-genome resequencing, constructed high-density map from population, incorporating 5,250 SNP markers across 15 linkage groups, covering 3,328.51 cM with an average marker interval distance of...
