| 1 | Metabolic analyses reveal different mechanisms of leaf color change in two purple-leaf tea plant (Camellia sinensis L.) cultivars显示文摘Purple-leaf tea plants,as anthocyanin-rich cultivars,are valuable materials for manufacturing teas with unique colors or flavors.In this study,a new purple-leaf cultivar“Zixin”(“ZX”)was examined,and its biochemical variation and mechanism of leaf color change were elucidated.The metabolomes of leaves of“ZX”at completely purple,intermediately purple,and completely green stages were analyzed using ultra-performance liquid chromatography quadrupole time of flight mass spectrometry(UPLC-QTOF-MS).Metabolites in the flavonoid biosynthetic pathway remained at high levels in purple leaves,whereas intermediates of porphyrin and chlorophyll metabolism and carotenoid biosynthesis exhibited high levels in green leaves.In addition,fatty acid metabolism was more active in purple leaves,and steroids maintained higher levels in green leaves.Saponin,alcohol,organic acid,and terpenoid-related metabolites also changed significantly during the leaf color change process.Furthermore,the substance changes between“ZX”and“Zijuan”(a thoroughly studied purple-leaf cultivar)were also compared.The leaf color change in“Zijuan”was mainly caused by a decrease in flavonoids/anthocyanins.However,a decrease in flavonoids/anthocyanins,an enhancement of porphyrin,chlorophyll metabolism,carotenoid biosynthesis,and steroids,and a decrease in fatty acids synergistically caused the leaf color change in“ZX”.These findings will facilitate comprehensive research on the regulatory mechanisms of leaf color change in purple-leaf tea cultivars. | Jiazhi Shen Zhongwei Zou Xuzhou Zhang Lin Zhou Yuhua Wang Wanping Fang Xujun Zhu | 2018 | Horticulture Research2018,5,1: | 22 |
| 2 | Exogenous abscisic acid significantly affects proteome in teaplant (Camellia sinensis) exposed to drought stress显示文摘Tea[Camellia sinensis(L.)O.Kuntze]is an important economic crop,and drought is the most important abiotic stress affecting yield and quality.Abscisic acid(ABA)is an important phytohormone responsible for activating drought resistance.Increased understanding of ABA effects on tea plant under drought stress is essential to develop drought-tolerant tea genotypes,along with crop management practices that can mitigate drought stress.The objective of the present investigation is evaluation of effects of exogenous ABA on the leaf proteome in tea plant exposed to drought stress.Leaf protein patterns of tea plants under simulated drought stress[(polyethylene glycol(PEG)-treated]and exogenous ABA treatment were analyzed in a time-course experiment using two-dimensional electrophoresis(2-DE),followed by matrix-assisted laser desorption/ionization time-of-flight(MALDI-TOF)mass spectrometry(MS).Among the 72 protein spots identified by MALDI-TOF MS,16 proteins were downregulated and two were upregulated by exogenous ABA.The upregulated proteins have roles in glycolysis and photosystem II stabilization.Twenty-one protein spots were responsive to drought stress and most participate in carbohydrate and nitrogen metabolism,control of reactive oxygen species(ROS),defense,signaling or nucleic acid metabolism.The combined treatments of exogenous ABA and drought showed upregulation of 10 protein spots at 12 h and upregulation of 11 proteins at 72 h after initiation of drought stress.The results support the importance of the role that ABA plays in the tea plant during drought stress,by improving protein transport,carbon metabolism and expression of resistance proteins. | Lin Zhou Hui Xu Sue Mischke Lyndel W Meinhardt Dapeng Zhang Xujun Zhu Xinghui Li Wanping Fang | 2014 | Horticulture Research2014,1,1: | 12 |
| 3 | Developing single nucleotide polymorphism(SNP)markers from transcriptome sequences for identification of longan(Dimocarpus longan)germplasm显示文摘Longan(Dimocarpus longan Lour.)is an important tropical fruit tree crop.Accurate varietal identification is essential for germplasm management and breeding.Using longan transcriptome sequences from public databases,we developed single nucleotide polymorphism(SNP)markers;validated 60 SNPs in 50 longan germplasm accessions,including cultivated varieties and wild germplasm;and designated 25 SNP markers that unambiguously identified all tested longan varieties with high statistical rigor(P<0.0001).Multiple trees from the same clone were verified and off-type trees were identified.Diversity analysis revealed genetic relationships among analyzed accessions.Cultivated varieties differed significantly from wild populations(Fst=0.300;P<0.001),demonstrating untapped genetic diversity for germplasm conservation and utilization.Within cultivated varieties,apparent differences between varieties from China and those from Thailand and Hawaii indicated geographic patterns of genetic differentiation.These SNP markers provide a powerful tool to manage longan genetic resources and breeding,with accurate and efficient genotype identification. | Boyi Wang Hua-Wei Tan Wanping Fang Lyndel W Meinhardt Sue Mischke Tracie Matsumoto Dapeng Zhang | 2015 | Horticulture Research2015,2,1: | 6 |
| 4 | Identification of the varietal origin of processed loose-leaf tea based on analysis of a single leaf by SNP nanofluidic array显示文摘Tea is an important cash crop, representing a $40 billion-a-year global market. Differentiation of the tea market has resulted in increasing demand for tea products that are sustainably and responsibly produced. Tea authentication is important because of growing concerns about fraud involving premium tea products. Analytical technologies are needed for protection and value enhancement of high-quality brands. For loose-leaf teas, the challenge is that the authentication needs to be established on the basis of a single leaf, so that the products can be traced back to the original varieties. A new generation of molecular markers offers an ideal solution for authentication of processed agricultural products. Using a nanofluidic array to identify variant SNP sequences, we tested genetic identities using DNA extracted from single leaves of 14 processed commercial tea products. Based on the profiles of 60 SNP markers, the genetic identity of each tea sample was unambiguously identified by multilocus matching and ordination analysis. Results for repeated samples of multiple tea leaves from the same products(using three independent DNA extractions) showed 100% concordance, showing that the nanofluidic system is a reliable platform for generating tea DNA fingerprints with high accuracy. The method worked well on green, oolong, and black teas, and can handle a large number of samples in a short period of time. It is robust and cost-effective, thus showing high potential for practical application in the value chain of the tea industry. | Wanping Fang Lyndel W.Meinhardt Huawei Tan Lin Zhou Sue Mischke Xinghua Wang Dapeng Zhang | 2016 | The Crop Journal2016,4,4: | 4 |
| 5 | The tea plant CsLHT1 and CsLHT6 transporters take up amino acids, as a nitrogen source, from the soil of organic tea plantations显示文摘Organic tea is more popular than conventional tea that originates from fertilized plants.Amino acids inorganic soils constitute a substantial pool nitrogen(N)available for plants.However,the amino-acid contents in soils of tea plantations and how tea plants take up these amino acids remain largely unknown.In this study,we show that the amino-acid content in the soil of an organic tea plantation is significantly higher than that of a conventional tea plantation.Glutamate,alanine,valine,and leucine were the most abundant amino acids in the soil of this tea plantation.When 15 N-glutamate was fed to tea plants,it was efficiently absorbed and significantly increased the contents of other amino acids in the roots.We cloned seven CsLHT genes encoding amino-acid transporters and found that the expression of CsLHT1,CsLHT2,and CsLHT6 in the roots significantly increased upon glutamate feeding.Moreover,the expression of CsLHT1 or CsLHT6 in a yeast amino-acid uptake-defective mutant,22Δ10α,enabled growth on media with amino acids constituting the sole N source.Amino-acid uptake assays indicated that CsLHT1 and CsLHT6 are H^(+)-dependent high-and low-affinity amino-acid transporters,respectively.We further demonstrated that CsLHT1 and CsLHT6 are highly expressed in the roots and are localized to the plasma membrane.Moreover,overexpression of CsLHT1 and CsLHT6 in Arabidopsis significantly improved the uptake of exogenously supplied 15 N-glutamate and 15 N-glutamine.Taken together,our findings are consistent with the involvement of CsLHT1 and CsLHT6 in amino-acid uptake from the soil,which is particularly important for tea plants grown inorganic tea plantations. | Fang Li Chunxia Dong Tianyuan Yang Shilai Bao Wanping Fang William J.Lucas Zhaoliang Zhang | 2021 | Horticulture Research2021,8,1: | 3 |
| 6 | A Novel Anti-Human Syndecan-1 (CD138) Monoclonal Antibody 4B3: Characterization and Application显示文摘Syndecan-1 (CD138), a member of integral membrane heparin sulfate proteoglycans, is an essential matrix receptor for maintaining the normal morphological phenotypes. In this study, we generated a specific mouse anti-human syndecan-1 monoclonal antibody (mAb) 4B3 and identified it by competition assay with the available syndecan-1 mAb (BB4). Stained by 4B3, the expression of syndecan-1 was detected on tumor cell lines, such as 8226, U266, XG-1, XG-2, Daudi and Jurkat. The expression was also found on neuron stem cells. It was established that 4B3 mAb could inhibit XG-1 and XG-2 proliferation. The data not only determined that 4B3 mAb was a functional anti-human syndecan-1 mAb, but also indicated that syndecan-1 might be a valuable surface antigen and play an important role in regulation of tumor pathology and differentiation of neural stem cells. This novel antibody 4B3 may be value of study of tumor proliferation/survival mechanism and contributes to diagnosis and treatment of diverse diseases. | Wanping Sun Fengming Wang Fang Xie Guoqing Wang Jin Sun Gehua Yu Yuhua Qiu Xueguang Zhang | 2007 | Cellular & Molecular Immunology2007,4,3: | 1 |

| 11 | An ancient whole-genome duplication event and its contribution to flavor compounds in the tea plant (Camellia sinensis)显示文摘Tea,coffee,and cocoa are the three most popular nonalcoholic beverages in the world and have extremely high economic and cultural value.The genomes of four tea plant varieties have recently been sequenced,but there is some debate regarding the characterization of a whole-genome duplication(WGD)event in tea plants.Whether the WGD in the tea plant is shared with other plants in order Ericales and how it contributed to tea plant evolution remained unanswered.Here we re-analyzed the tea plant genome and provided evidence that tea experienced only WGD event after the core-eudicot whole-genome triplication(WGT)event.This WGD was shared by the Polemonioids-Primuloids-Core Ericales(PPC)sections,encompassing at least 17 families in the order Ericales.In addition,our study identified eight pairs of duplicated genes in the catechins biosynthesis pathway,four pairs of duplicated genes in the theanine biosynthesis pathway,and one pair of genes in the caffeine biosynthesis pathway,which were expanded and retained following this WGD.Nearly all these gene pairs were expressed in tea plants,implying the contribution of the WGD.This study shows that in addition to the role of the recent tandem gene duplication in the accumulation of tea flavor-related genes,the WGD may have been another main factor driving the evolution of tea flavor. | Ya Wang Fei Chen Yuanchun Ma Taikui Zhang Pengchuan Sun Meifang Lan Fang Li Wanping Fang | 2021 | Horticulture Research2021,8,1: | 0 |
| 12 | Progress and perspective on intercropping patterns in tea plantations显示文摘Intercropping,as one of the complex ecological cultivations,is an important tea plantation pattern.Compared to sole-cropping tea plantations,intercropping can improve the above-and below-ground environment,which is beneficial to tea plant growth,the formation of high tea quality and the increase of tea yield.In this review,we summarized the impacts of intercropping on the tea plantation environment(microclimate,biomass,soil nutrients,microorganisms and heavy metals),tea plants growth and tea yield.We then analyzed how intercropping affects the growth and metabolism of tea plants based on the impact of intercropping on the environment.As a result,the achievements and progress of tea plantation intercropping are summarized,the remaining problems of the current research on intercropping tea plantations are highlighted,and provide new insights for the advanced research of intercropping in tea plantations. | Xiaogang Lei Ting Wang Bin Yang Yu Duan Lin Zhou Zhongwei Zou Yuanchun Ma Xujun Zhu Wanping Fang | 2022 | Beverage Plant Research2022,2,1: | 0 |
| 13 | Inaugural Editorial显示文摘Many loved beverages worldwide are derived from plants.Some of the most important and popular examples of these beverage crops are tea,coffee,and cacao,which provide great economic value from source to consumption across the world.The buds and tender leaves of the tea plant(Camellia sinensis)can be used to make various tea products by specific processing or manufacture methods.The seeds(beans)of the coffee(Coffea arabica and C.canephora)and cacao(Theobroma cacao)trees once roasted create products with complex aromas and tastes loved by many on a daily basis.As the most popular non-alcoholic drinks in the world outside of pure water,they each contain an abundant mixture of specific secondary metabolites.These secondary metabolites not only give the beverage unique aroma,taste and flavor,they also have been correlated or directly shown through hundreds of clinical peer reviewed studies to benefit human health.These extensive studies have been reported and indicated that and tea,coffee,and cacao drinks are able to reduce the risk of memory disorders,Parkinson's disease,type-2 diabetes,cancer,and so much more.Many other crops have also been used for beverage making,such as cacti,coconut,etc. | Zongmao Chen Brian Schaneberg Liang Chen Wanping Fang | 2021 | Beverage Plant Research2021,1,1: | 0 |
| 14 | Targeted metabolomics reveals dynamic changes during the manufacturing process of Yuhua tea,a stir-fried green tea显示文摘The chemical composition of Yuhua tea is in a state of constant change during tea processing.However,the dynamic changes in this complex metabolic process remain unclear.Therefore,we detected the changes of compounds in the five stages of processing of Yuhua tea,and carried out metabolomic analysis based on UPLC–MS.In total,898 metabolites were detected in the five different stages.In the spreading and fixation processes,the differences in metabolites were the most significant,with 127 and 150 metabolites,respectively,undergoing significant changes.During the spreading period,the levels of amino acids and their derivatives,as well as flavonoids,increased sharply,and most continued to increase or stabilized after spreading.In addition,only 26 and 95 metabolites changed significantly during the rolling and drying processes,respectively.Orthogonal projections to latent structures-discriminant analysis showed that the metabolomics of tea changed significantly during the manufacturing process,especially amino acids and derivatives,flavonoids and lipids.This study provides a comprehensive overview of the metabolic changes during the processing of stir-fried green tea,which has potential significance for quality control and flavor improvement of tea. | Kexin Zhang Taiyu Ren Jieren Liao Shan Wang Zhongwei Zou Yuanchun Ma Fang Li Wanping Fang Xujun Zhu | 2021 | Beverage Plant Research2021,1,1: | 0 |
