7Varietal identification of tea(Camellia sinensis)using nanofluidic array of single nucleotide polymorphism(SNP)markers显示文摘Apart from water,tea is the world’s most widely consumed beverage.Tea is produced in more than 50 countries with an annual production of approximately 4.7 million tons.The market segment for specialty tea has been expanding rapidly owing to increased demand,resulting in higher revenues and profits for tea growers and the industry.Accurate varietal identification is critically important to ensure traceability and authentication of premium tea products,which in turn contribute to on-farm conservation of tea genetic diversity.Using a set of single nucleotide polymorphism(SNP)markers developed from the expressed sequence tag(EST)database of Camilla senensis,we genotyped deoxyribonucleic acid(DNA)samples extracted from a diverse group of tea varieties,including both fresh and processed commercial loose-leaf teas.The validation led to the designation of 60 SNPs that unambiguously identified all 40 tested tea varieties with high statistical rigor(p<0.0001).Varietal authenticity and genetic relationships among the analyzed cultivars were further characterized by ordination and Bayesian clustering analysis.These SNP markers,in combination with a high-throughput genotyping protocol,effectively established and verified specific DNA fingerprints for all tested tea varieties.This method provides a powerful tool for variety authentication and quality control for the tea industry.It is also highly useful for the management of tea genetic resources and breeding,where accurate and efficient genotype identification is essential.Wan-Ping Fang Lyndel W Meinhardt Hua-Wei Tan Lin Zhou Sue Mischke Dapeng Zhang 2014Horticulture Research2014,1,1:13
8Exogenous 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 2014Horticulture Research2014,1,1:12
9Inhibition of Mcl-1 enhances cell death induced by the Bcl-2-selective inhibitor ABT-199 in acute myeloid leukemia cells显示文摘Acute myeloid leukemia(AML)is a serious disease.The 5-year survival rates remain frustratingly low(65%for children and 26%for adults).Resistance to frontline chemotherapy(usually cytarabine)often develops;therefore a new treatment modality is needed.Bcl-2 family proteins play an important role in balancing cell survival and apoptosis.The antiapoptotic Bcl-2 family proteins have been found to be dysregulated in AML.ABT-199,a BH3 mimetic,was developed to target antiapoptotic protein Bcl-2.Although ABT-199 has demonstrated promising results,resistance occurs.Previous studies in AML show that ABT-199 alone decreases the association of proapoptotic protein Bim with Bcl-2,but this is compensated by increased association of Bim with prosurvival protein Mcl-1,stabilizing Mcl-1,resulting in resistance to ABT-199.In this study,we investigated the antileukemic activity of the Mcl-1-selective inhibitor A-1210477 in combination with ABT-199 in AML cells.We found that A-1210477 synergistically induced apoptosis with ABT-199 in AML cell lines and primary patient samples.The synergistic induction of apoptosis was decreased upon Bak,Bax and Bim knockdown.While A-1210477 treatment alone also increased Mcl-1 protein levels,combination with ABT-199 reduced binding of Bim to Mcl-1.Our results demonstrate that sequestration of Bim by Mcl-1,a mechanism of ABT-199 resistance,can be abrogated by combined treatment with the Mcl-1 inhibitor A-1201477.Daniel A Luedtke Xiaojia Niu Yihang Pan Jianyun Zhao Shuang Liu Holly Edwards Kang Chen Hai Lin Jeffrey W Taub Yubin Ge 2017Signal Transduction and Targeted Therapy2017,2,1:11
