1Species of Lasiodiplodia associated with mango in Brazil显示文摘Mango(Mangifera indica)is a major tropical fruit species cultivated in Brazil.The objective of this study was to identify species of Lasiodiplodia associated with dieback and stem-end rot of mango in the semi-arid region of Northeastern Brazil,and compare the species in relation to mycelial growth,pathogenicity and virulence.A total of 120 isolates of Lasiodiplodia were used and identifications were made using a combination of morphology and phylogenetic analysis based on partial translation elongation factor 1-αsequence(EF1-α)and internal transcribed spacers(ITS).The following species were identified:Lasiodiplodia crassispora,L.egyptiacae,L.hormozganensis,L.iraniensis,L.pseudotheobromae,L.theobromae and Lasiodiplodia sp..Lasiodiplodia theobromae was the most frequently isolated species,which represented 41%of all the isolates.Only this species had been previously reported on mango in Brazil,while the other species represent the first report associated with mango tree diseases in this country.Lasiodiplodia crassispora is reported for the first time associated with mango diseases worldwide.There were significant differences in mycelial growth rates among the Lasiodiplodia species and also in the optimum temperature for growth.All species of Lasiodiplodia were pathogenic on mango fruit.There were significant differences in virulence among the species,wherein L.hormozganensis and Lasiodiplodia sp.were the most virulent,while the least virulent were L.iraniensis,L.pseudotheobromae,L.crassispora and L.egyptiacae.Marília W.Marques Nelson B.Lima Marcos Antônio de Morais Jr Maria Angélica G.Barbosa Breno O.Souza Sami J.Michereff Alan J.L.Phillips Marcos P.S.Câmara 2013Fungal Diversity2013,,4:2
2Species of Lasiodiplodia associated with papaya stem-end rot in Brazil显示文摘This study aims to identify and characterize species of Lasiodiplodia associated with stem-end rot of papaya in six different populations in the Northeast of Brazil.Fungal identifications were made using a combination of morphology together with a phylogenetic analysis based on partial translation elongation factor 1-αsequence(EF-1α)and internal transcribed spacers(ITS).Five species of Lasiodiplodia were identified:Lasiodiplodia brasiliense sp.nov.,L.hormozganensis,L.marypalme sp.nov.,L.pseudotheobromae and L.theobromae.Only L.theobromae had previously been reported in papaya,while all the other species are reported for the first time in association with this host in Brazil and worldwide.Lasiodiplodia theobromae was the most prevalent species.All species of Lasiodiplodia were pathogenic on papaya fruit,with L.hormozganensis being the most virulent.Mariote S.B.Netto Iraíldes P.Assuncao Gaus S.A.Lima Marília W.Marques Waléria G.Lima Jean H.A.Monteiro Valdir de Queiroz Balbino Sami J.Michereff Alan J.L.Phillips Marcos P.S.Camara 2014Fungal Diversity2014,,4:2

6Botryosphaeria, Neofusicoccum, Neoscytalidium and Pseudofusicoccum species associated with mango in Brazil显示文摘Members of the Botryosphaeriaceae are well known fungi associated with dieback,canker and fruit rot on various hosts worldwide,including mango.The aim of this study was identify a large collection of Botryosphaeriaceae species associated with dieback and stem-end rot of mango in the semi-arid region of Northeastern Brazil,and compare the species in relation to mycelial growth,pathogenicity and virulence.A total of 115 isolates were sampled and based on morphology and DNA sequence data(ITS and EF1-α)seven taxa were identified,namely,Botryosphaeria dothidea,B.mamane,Fusicoccum fabicercianum,Neofusicoccum parvum,N.brasiliense sp.nov,Neoscytalidium dimidiatum and Pseudofusicoccum stromaticum.B.dothidea and P.stromaticum were the most commonly isolated species,which represented 37%and 33%of all isolates respectively.B.mamane is reported for the first time in association with mango diseases worldwide.There were significant differences among the species obtained in this study in relation to optimum temperature for mycelial growth and mycelial growth rates.All species were pathogenic on mango fruit.There were significant differences in virulence among the species,with Ne.dimidiatum and N.parvum being the most virulent species,while P.stromaticum was the least virulent.Marília W.Marques Nelson B.Lima Marcos A.de Morais Jr Sami J.Michereff Alan J.L.Phillips Marcos P.S.Câmara 2013Fungal Diversity2013,,4:1

8林奇综合征患者中同时具有不同遗传性肿瘤综合征的种系变异显示文摘背景与目的林奇综合征(lynch syndrome,LS)是一种遗传性疾病,LS患者罹患结直肠癌、子宫内膜癌和其他与DNA错配修复基因发生种系突变相关肿瘤的风险较高。LS的传统遗传诊断方法为对与疑似综合征相关的基因进行桑格测序。二代测序技术(next-generation sequencing,NGS)可同时对大量遗传性癌基因进行测序。本研究旨在探究林奇综合征患者中是否存在其他遗传性种系病理癌基因变异。方法我们选取先前已利用桑格测序遗传诊断法确诊的84例LS先证者作为研究对象,通过杂交捕获一组94个商业化的遗传癌基因,随后对这些捕获的样本进行NGS测序。按照美国医学遗传学和基因组学标准,对这些变异的临床意义进行分类。利用桑格测序验证NGS的结果。在可能的情况下,利用桑格测序进一步在先证者的亲属中进行新发现种系变异基因的遗传分析。结果我们从84个家族中鉴定出5(6%)个至少含有2个种系致病变异的家族,这些变异具有高或中等的诱发不同显性癌症的风险,这些家族的种系致病变异如下:[MLH1-BRCA2-NBN]、[MLH1-BRCA1]、[MSH2-ATM]、[MSH6-NF1]和[MLH1-FANCA]。有趣的是,这5个家族中只有1个家族表现出与新的致病变异相关的临床表型。含有3个致病变异基因[MLH1-BRCA2-NBN]的家族显示出LS、乳腺和卵巢癌综合征相关肿瘤的高度聚集特性。结论我们的研究表明,癌症易感基因中,同时发生多个致病变异是LS病例的显著特点。在大部分的病例中,继发性致病变异与临床表型不相关。将来需要进一步验证这些结论并阐明其临床影响。只有表现出复杂的临床表型家族才有必要重新对LS进行分析。Rosario Ferrer-Avargues María Isabel Castillejo Estela Dámaso Virginia Díez-Obrero NoemíGarrigos Tatiana Molina Alan Codoñer-Alejos Ángel Segura Ana Beatriz Sánchez-Heras Adela Castillejo JoséLuis Soto 2022癌症2022,41,5:0
