To efficiently protect and exploit germplasm resources for marker development breeding purposes, we must accurately depict the features of tea populations. This study focuses on Camellia sinensis (C. sinensis) population aims to (i) identify single nucleotide polymorphisms (SNPs) genome level, (ii) investigate genetic diversity structure, (iii) characterize linkage disequilibrium (LD) pattern facilitate next genome-wide association mapping marker-assisted selection. We collected 415...
Flavonoids, theanine and caffeine are the main secondary metabolites of tea plant (Camellia sinensis), which account for tea's unique flavor quality health benefits. The biosynthesis pathways these have been extensively studied at transcriptional level, but regulatory mechanisms still unclear. In this study, to explore transcriptome diversity complexity plant, PacBio Iso-Seq RNA-seq analysis were combined obtain full-length transcripts profile changes in gene expression during leaf...
Withering time of fresh leaves is a key factor affecting the stability flavor quality Taiping Houkui tea (TPHK). It's effect and mechanism on formation in TPHK remain unelucidated. Here, metabolomics transcriptomics were combined to comprehensively investigate changes main compounds expression patterns related genes under different withering times. The results showed that had greatest influence content most amino acids aroma volatiles. relative volatiles was observed be highest at 6–8 h...
Abstract Background Tea plants originated in southwestern China. Guizhou Plateau is an original center of tea plants, and rich germplasm resources. However, the genetic diversity, population structure distribution characteristics cultivated-type region are unknown. In this study, we explored diversity geographical accessions Plateau. Results We used 112,072 high-quality genotyping-by-sequencing to analyze principal components, phylogeny, structure, linkage disequilibrium, develop a core...
Taiping Houkui (TPHK) is prevalent green tea in China, its flavor quality significantly influenced by different production regions. However, the key compounds responsible for these discrepancies remain unclearly. Here, TPHK samples were produced from fresh leaves of 'Shidacha 2' cultivar planted 14 distinct In samples, a total 33 non-volatile identified and quantified. Partial least-squares discriminant analysis (PLS-DA) reveal that theanine glutamate main umami compounds, caffeine imparted...
The tea green leafhopper [<italic>Empoasca</italic> (<italic>Matsumurasca</italic>) <italic>onukii</italic> Matsuda] is one of the most dominant pests in production regions China, greatly impacting yield and quality. Extensive studies have attributed plant defense response to pest infestation activation hormone signals, but role hormones plants feeding <italic>E. onukii</italic> not clear. RNA-seq was performed on leaf samples collected at different time points (6, 24 48 h) after with...
Abstract Tea plants are crops with economic, health and cultural value. Catechin, caffeine theanine the main secondary metabolites of taste. In process germplasm collection, we found a resource in Sandu Aquatic Autonomous County Guizhou (SDT) that possessed significantly different characteristic compared cultivar ‘Qiancha 1’. SDT is rich theobromine theophylline, possesses low levels (−)-epicatechin-3-gallate, (−)-epigallocatechin-3-gallate, content, almost free caffeine. However, research...
Abstract Background BAHD acyltransferases are among the largest metabolic protein domain families in genomes of terrestrial plants and play important roles plant growth development, aroma formation, biotic abiotic stress responses. Little is known about BAHDs tea plant, a cash crop rich secondary metabolites. Results In this study, 112 genes ( CsBAHD01 - CsBAHD112 ) were identified from genome, with 85% (98/112) unevenly distributed across 15 chromosomes. The number gene family members has...
An accurate depiction of the genetic relationship, development core collection, and genome-wide association analysis (GWAS) are key for effective exploitation utilization resources. Here, genotyping-by-sequencing (GBS) was used to characterize 415 tea accessions mostly collected from Guizhou region in China. A total 30,282 high-quality SNPs estimate relationships, develop collections, perform GWAS. We suggest 198 148 represent set mini-core set, which consist 47% 37% whole respectively,...
Alternative splicing (AS) increases the diversity of transcripts and proteins through selection different splice sites plays an important role in growth, development stress tolerance plants. With release reference genome tea plant (Camellia sinensis) transcriptome sequencing, researchers have reported existence AS However, there is a lack platform, centered on RNA-seq datasets, that provides comprehensive information AS.To facilitate access to reveal molecular function plants, we established...
Summary Numerous herbivore‐induced plant volatiles (HIPVs) play important roles in defense. In tea plants ( Camellia sinensis ), (Z)‐3‐hexenyl acetate (3‐HAC) has been characterized as associated with resistance to herbivores. To date, how biosynthesize and regulate 3‐HAC resist herbivores remain unclear. Based on transcriptomes assembled from Ectropis obliqua‐ fed leaves, a cDNA encoding BAHD acyltransferase, namely CsCHAT1 , was highly induced leaves E. obliqua . Enzymatic assays showed...
PYL (Pyrabactin resistance 1-like) protein is a receptor of abscisic acid (ABA), which plays an important role in ABA signaling and influences plant growth development stress response. However, studies on gene family tea plants have not been reported.In this study, we identified 20 genes from the reference genome ('Shuchazao'). Phylogeny analysis indicated that PYLs other species were clustered into seven groups. The promoter region contains large number cis-elements related to hormones...
ADP ‐ribosylation factors ( ARFs ) are small GTP ‐binding proteins that regulate a wide variety of cell functions. Previously, we isolated new ARF , ZmArf2 from maize Zea mays ). Sequence and expression characteristics indicated might play critical role in the early stages endosperm development. In this study, investigated function by analysis its activity subcellular localization. We also over‐expressed Arabidopsis measured organ size counted numbers. The levels five size‐associated genes...
The complete chloroplast (cp) genome sequence of Camellia sinensis var. cultivar 'FuDingDaBaiCha' (FD), one the key contributors to history tea breeding in China, was determined this study. cp FD is 157,025 bp length, including a large single-copy (LSC, 86,586 bp), small (SSC, 18,277 and pair inverted repeats (IRa IRb, 26,081 bp). overall GC content 37.3%. A total 137 genes were predicted, 92 protein-coding genes, 37 tRNA eight rRNA genes. Phylogenetic analysis showed that closely related C....
