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...
Summary Cultivars of purple tea ( Camellia sinensi s) that accumulate anthocyanins in place catechins are currently attracting global interest their use as functional health beverages. RNA‐seq normal (LJ43) and Zijuan (ZJ) cultivars identified the transcription factor CsMYB75 phi (F) class glutathione transferase CsGSTF1 being associated with anthocyanin hyperaccumulation. Both genes mapped a quantitative trait locus (QTL) to bud leaf color (BLC) F 1 populations, promoting expression...
Despite the worldwide consumption and high economic importance of tea, plant (Camellia sinensis) is not well studied in molecular biology. Under few circumstances which studied, C. sinensis flowers, are important for reproduction cross-breeding, receive less emphasis than investigation its leaves or roots. Using high-throughput Illumina RNA sequencing, we analyzed a floral transcriptome, 26.9 million clean reads were assembled into 75,531 unigenes averaging 402 bp. Among them, 50,792 (67.2%)...
Abstract As a vital beverage crop, tea has been extensively planted in tropical and subtropical regions. Nitrogen (N) levels forms are closely related to quality. Based on different N forms, we studied changes NO 3 − NH 4 + fluxes roots utilizing scanning ion-selective electrode technique. Our results showed that under both single mixed influx rates of were much lower than those , suggesting preference for tea. With the increase concentration, rate increased more . The solution without...
The genetic mechanisms that underlie phenotypic differentiation in breeding animals have important implications evolutionary biology and agriculture. However, the contribution of cis-regulatory variants to pig phenotypes is poorly understood. Therefore, our aim was elucidate molecular by which non-coding cause differences pigs combining analyses functional genomics.We obtained a high-resolution phased chromosome-scale reference genome with contig N50 18.03 Mb for Luchuan breed (a...
Tea (Camellia sinensis L.) is a popular world beverage, and propagation of tea plants chiefly depends on the formation adventitious roots in cuttings. To better understand potential mechanisms involved root formation, we performed transcriptome analysis single nodal cuttings C. treated with or without indole-3-butyric acid (IBA) using Illumina sequencing method. Totally 42.5 million RNA-Seq reads were obtained these assembled into 59,931 unigenes, an average length 732 bp N50 1292 bp. In...
Self-incompatibility (SI) is under genetic control and prevents inbreeding depression in angiosperms. SI mechanisms are quite complicated still poorly understood many plants. Tea (Camellia sinensis L.) belonging to the family of Theaceae, exhibits high levels heterozygosity. Uncovering molecular basis tea plant may enhance breeding simplify genomics research for whole family. The growth pollen tubes following selfing crossing was observed using fluorescence microscopy. Self-pollen grew...
The ratio of dihydroxylated to trihydroxylated catechins (RDTC) is an important indicator tea quality and biochemical marker for the study genetic diversity. It reported be under control but underlying mechanism not well understood. Flavonoid 3′-hydroxylase (F3′H) flavonoid 3′,5′-hydroxylase (F3′5′H) are key enzymes involved in formation catechins. transcriptome HPLC analysis samples from Longjing43 Zhonghuang2 shading treatment were performed assess F3′H F3′5′H genes that might affect RDTC....
Catechins are the main polyphenol compounds in tea (Camellia sinensis). To understand relationship between gene expression and product accumulation, levels of catechins relative expressions key genes leaves different developmental stages were analyzed. The amounts differed significantly stages, except for gallocatechin gallate. Close correlations synthesis accumulation identified. Correlation analysis showed that chalcone synthase 1, 3, anthocyanidin reductase 2 leucoanthocyanidin positively...
Flavonoids are important components that confer upon tea plants a unique flavour and health functions. However, the traditional breeding method for selecting cultivar with high or flavonoid content is time consuming labour intensive. High-density genetic map construction associated quantitative trait locus (QTL) mapping provides an effective way to facilitate improvement in plant breeding. In this study, F1 population (LJ43×BHZ) was genotyped using 2b-restriction site-associated DNA (2b-RAD)...
Theanine, a unique amino acid in Camellia sinensis, accounts for more than 50% of total free acids tea and has significant contribution to the quality green tea. Previous research indicated that theanine is synthesized from glutamic (Glu) ethylamine mainly roots, accumulation depends on availability which derived alanine (Ala) decarboxylation catalyzed by decarboxylase (AlaDC). However, specific gene encoding AlaDC protein remains be discovered plants or other species. To explore plants,...
Tea plant breeding or cultivation mainly involves propagation via cuttings, which not only ensures the inheritance of excellent characteristics mother but also facilitates mechanized management. The formation adventitious root (AR) determines success cutting-based propagation, and auxin is an essential factor involved in this process. To understand molecular mechanism underlying AR nodal tea transcriptome endogenous hormone analysis was performed on stem bases red (mature)- green...
Abstract Purple tea, rich in anthocyanins, has a variety of health benefits and is attracting global interest. However, the regulation mechanism anthocyanin purple tea populations not been extensively studied. In this experiment, RNA-seq, BSA-seq, BSR-seq were performed using 30 individuals with extreme colors (dark-purple green) an F1 population ‘Zijuan’ ‘Jinxuan’. The results show that 459 genes differentially expressed green leaves, among which involved synthesis transport pathway, such...
