While plants produce reactive oxygen species (ROS) for stress signaling and pathogen defense, they need to remove excessive ROS induced during responses in order minimize oxidative damage. How can fine-tune this balance meet such conflicting needs? Here, we show that XANTHINE DEHYDROGENASE1 (XDH1) Arabidopsis thaliana appears play spatially opposite roles serve purpose. Through a large-scale genetic screen, identified three missense mutations XDH1 impair XDH1's enzymatic functions...
'Ziyan' is a novel anthocyanin-rich tea cultivar with dark purple young shoots. However, how its anthocyanin accumulation affected by environmental factors, such as ultraviolet (UV), remains unclear. In this study, we observed that UV light treatments stimulated in leaves, and further analyzed the underlying mechanisms at gene expression enzyme activity levels. addition, catechins chlorophyll contents of shoots under different were also changed. The results showed total anthocyanins three...
Ferroptosis, a form of regulated cell death, has been widely explored as novel target for the treatment diseases. The failure antioxidant system can induce ferroptosis. Epigallocatechin-3-Gallate (EGCG) is natural in tea; however, whether EGCG regulate ferroptosis liver oxidative damage, well exact molecular mechanism, unknown. Here, we discovered that iron overload disturbed homeostasis mice, leading to stress and damage by activating However, supplementation alleviated caused inhibiting...
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%)...
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...
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)...
Microbes are critical for the flavor development of Sichuan South-road Dark Tea (SSDT) during pile-fermentation. However, their mechanism action has not been fully elucidated yet. In this study, SSDT microbial metagenome obtained from different locations piled tea center pile-fermentation metaphase were functionally annotated, and glycoside hydrolase (GH) genes core functional strain comprehensively analyzed. The results revealed that carbohydrate metabolism (8.2%) predominant in total...
The levels of free amino acids (FAAs) and the timing bud flush (TBF) are among most economic traits tea plants (Camellia sinensis). Investigating genetic variation characteristics FAAs their potential associations with TBF is critical for breeding new cultivars high value. In this study, we utilized 'Emei Wenchun' (♀) × 'Chuanmu 217' (♂) filial 1 (F1) population (n = 208) measured FAA contents in "one two leaves" samples across spring seasons one summer season using high-performance liquid...
Summary Biotrophic pathogens are believed to strategically manipulate sugar transport in host cells enhance their access carbohydrates. However, mechanisms of translocation from biotrophic fungi such as powdery mildew across the plant–haustorium interface remain poorly understood. To investigate this question, systematic subcellular localisation analysis was performed for all 14 members monosaccharide transporter protein (STP) family Arabidopsis thaliana . The best candidate AtSTP8 further...
The timing of bud flush (TBF) in the spring is one most important agronomic traits tea plants (Camellia sinensis). In this study, we designed an open-pollination breeding program using 'Emei Wenchun' (EW, a clonal cultivar with extra-early TBF) as female parent. A half-sib population (n = 388) was selected for genotyping specific-locus amplified fragment sequencing. results enabled identification paternity 294 (75.8%) offspring, including 11 (2.8%) from EW selfing and 217 (55.9%) assigned to...
In this study, the dynamic changes of different anthocyanins in processing 'Ziyan' tea wine were investigated quantitatively. Results showed that six types anthocyanins, namely petunidin, malvidin, pelargonidin, delphinidin, cyanidin and peonidin, as well two co-pigmented substances, procyanidins flavonoids, detected wine. As fermentation proceeded, contents peonidin decreased. Among them, pelargonidin a tendency decreasing first, then increasing finally decreasing, whereas delphinidin...
Owing to the potential health benefits, anthocyanin‐rich teas ( Camellia sinensis ) have attracted interest over past decade. Previously, we developed cultivar ‘Ziyan,’ which has dark‐purple leaves because of accumulation a high amount anthocyanins. In this study, performed genetic analysis tea and 176 its naturally pollinated offspring. For two consecutive years, quantified anthocyanins catechins ‘Ziyan’ offspring population. While >60% accumulated less than half 17 (2018) 15 (2019)...
Nitrogen (N) is a key regulator in the growth of tea plants and synthesis amino acids (AAs) related secondary metabolites, thus affecting yield quality leaves. Increased N fertilization significantly improves plants, but applying excess nitrogen wastes resources causes pollution problems. Herein, we employed morphological, physiological, metabolomic, RNA-seq methods to study response ‘Ziyan’ roots high N. High supply induced an increase arginine (Arg), asparagine (Asn), glutamine (Gln)...
Microbes are critical in the Sichuan South-road Dark Tea (SSDT) organoleptic quality development during pile-fermentation. Piled tea center at fermenting metaphase is crucial for conversion of its components. In this study, we investigated microbial community piled SSDT below stacked surface 15 cm (SSDTB), 50 (SSDTX), and 85 (SSDTH) on second turning time pile-fermentation, respectively. Results showed that SSDTH SSDTB had a higher similarity community. Pantoea (36.8%), Klebsiella (67.7%),...
