测定了中国迁粉蝶属3种4亚种以及迁粉蝶指名亚种5个生态型的线粒体COⅠ基因和NDⅠ基因部分序列,以灵奇尖粉蝶为外群,分别采用最大简约法、最大似然法和贝叶斯法构建分子系统树,探讨了中国迁粉蝶属3种4亚种间的系统发育关系,并首次明确了迁粉蝶指名亚种5个生态型的亲缘关系。结果显示在测得的COⅠ基因661bp序列和NDⅠ基因472bp序列中,有变异位点227个,简约位点119个,A+T含量(75.5%)明显偏高。迁粉蝶属4亚种分子系统关系为:(镉黄迁粉蝶指名亚种+((梨花迁粉蝶指名亚种+梨花迁粉蝶海南亚种)+迁粉蝶指名亚种)),迁粉蝶指名亚种5个生态型分子系统关系为:(无纹型+((有纹型+红角型)+(银斑型+血斑型)))。 相似文献

【目的】由于绢粉蝶属Aporia和妹粉蝶属Mesapia的分类地位尚存在争议,本研究基于COI和EF-1α基因探讨它们的系统发育关系。【方法】对采自中国的19个种(含绢粉蝶属13个种,妹粉蝶属1种以及用作外群的另外3个属的5个种)的COI和EF-1α基因部分序列进行了测定和分析;依据这2个基因的联合序列采用最大似然法(maximum likelihood,ML)和贝叶斯法(Bayesian inference,BI)构建了这些种的系统发育树。【结果】序列分析结果显示,测得的COI序列长度为657 bp,EF-1α序列长度为642 bp,联合后获得的序列总长为1 299 bp,其中变异位点439个,简约信息位点249个;序列A+T的含量明显高于C+G的含量。系统发生分析结果显示,除外群外,其余种类形成单系群(BV=100,PP=1.00),且分成两大支,一支为(奥倍绢粉蝶A.oberthuri+锯纹绢粉A.goutellei)+(丫纹绢粉蝶A.delavayi+(完善绢粉蝶A.agathon+(马丁绢粉蝶A.martineti+(大翅绢粉蝶A.largeteaui+巨翅绢粉蝶A.gigantea)))),另一支为普通绢粉蝶A.genestieri+(中亚绢粉蝶A.leucodice+((绢粉蝶A.crataegi+灰翅绢粉蝶A.potanini)+(妹粉蝶M.peloria+(暗色绢粉蝶A.bieti+小檗绢粉蝶A.hippia))))。【结论】本研究结果支持妹粉蝶属应为绢粉蝶属的异名,且绢粉蝶属内不再划分亚属和种组。 相似文献

测定了粉蝶科的粉蝶亚科和黄粉蝶亚科14属共24种线粒体COⅠ和Cyt b基因部分序列,并从GenBank中下载了2种粉蝶的同源序列,以眼蝶科的2个物种为外类群,运用NJ法、贝叶斯法分别重建了分子系统树,探讨了它们的系统发生关系。基因序列分析结果表明,经比对和处理后的序列总长度为1111bp,其中变异位点478个,简约位点382个,碱基T、C、A、G平均含量为39.9%、16.9%、30.9%、12.3%,A+T含量和C+G含量分别为70.8%和29.2%。分子系统树显示:黄粉蝶亚科不是单系群,但其中迁粉蝶属和豆粉蝶属在不同的分析方法中均聚合在一起。粉蝶亚科形成一个独立的支系,其中,襟粉蝶族为并系群;粉蝶族的粉蝶属、飞龙粉蝶属和云粉蝶属具有较近的亲缘关系。 相似文献

正Dear Editor,In December 2019, a novel human coronavirus caused an epidemic of severe pneumonia(Coronavirus Disease 2019,COVID-19) in Wuhan, Hubei, China(Wu et al. 2020; Zhu et al. 2020). So far, this virus has spread to all areas of China and even to other countries. The epidemic has caused 67,102 confirmed infections with 1526 fatal cases 相似文献

Curcumin is the yellow pigment of turmeric that interacts irreversibly forming an adduct with thioredoxin reductase (TrxR), an enzyme
responsible for redox control of cell and defence against oxidative stress. Docking at both the active sites of TrxR was performed to compare
the potency of three naturally occurring curcuminoids, namely curcumin, demethoxy curcumin and bis-demethoxy curcumin. Results show
that active sites of TrxR occur at the junction of E and F chains. Volume and area of both cavities is predicted. It has been concluded by
distance mapping of the most active conformations that Se atom of catalytic residue SeCYS498, is at a distance of 3.56 from C13 of
demethoxy curcumin at the E chain active site, whereas C13 carbon atom forms adduct with Se atom of SeCys 498. We report that at least
one methoxy group in curcuminoids is necessary for interation with catalytic residues of thioredoxin. Pharmacophore of both active sites of
the TrxR receptor for curcumin and demethoxy curcumin molecules has been drawn and proposed for design and synthesis of most probable
potent antiproliferative synthetic drugs. 相似文献

The young pistils in the melanthioid tribes, Hewardieae, Petrosavieae and Tricyrteae, are uniformly tricarpellate and syncarpous. They lack raphide idioblasts. All are multiovulate, with bitegmic ovules. The Petrosavieae are marked by the presence of septal glands and incomplete syncarpy. Tepals and stamens adhere to the ovary in the Hewardieae and the Petrosavieae but not in the Tricyrteae. Two vascular bundles occur in the stamens of the Hewartlieae and Tricyrtis latifolia. Ventral bundles in the upper part of the ovary of the Hewardieae are continuous with compound septal bundles and placental bundles in the lower part. Putative ventral bundles occur in the alternate position in the Tricyrteae and putative placental bundles in the opposite. position in the Petrosavieae. The dichtomously branched stigma in each carpel of the Tricyrteae is supplied by a bifurcated dorsal bundle. 相似文献

Rasmussen’s encephalitis (RE) is a rare pediatric neurological disorder, and the exact etiology is not clear. Viral infection may be involved in the pathogenesis of RE, but conflicting results have reported. In this study, we evaluated the expression of both Epstein-Barr virus (EBV) and human herpes virus (HHV) 6 antigens in brain sections from 30 patients with RE and 16 control individuals by immunohistochemistry. In the RE group, EBV and HHV6 antigens were detected in 56.7% (17/30) and 50% (15/30) of individuals, respectively. In contrast, no detectable EBV and HHV6 antigen expression was found in brain tissues of the control group. The co-expression of EBV and HHV6 was detected in 20.0% (6/30) of individuals. In particular, a 4-year-old boy had a typical clinical course, including a medical history of viral encephalitis, intractable epilepsy, and hemispheric atrophy. The co-expression of EBV and HHV6 was detected in neurons and astrocytes in the brain tissue, accompanied by a high frequency of CD8+ T cells. Our results suggest that EBV and HHV6 infection and the activation of CD8+ T cells are involved in the pathogenesis of RE. 相似文献

正Dear Editor,Chikungunya virus (CHIKV), an arbovirus in the family of Togaviridae, genus Alphavirus, is transmitted by the A.aegyptii or A. albopictus mosquito, and causes disease in humans characterized by fever, rash, and arthralgia (Silva and Dermody 2017; Suhrbier 2019). It was first reported in 1953 in Tanzania, and caused only a few outbreaks and sporadic cases in Africa and Asia in last century. However, in the epidemic in 2004, CHIKV acquired mutations that conferred enhanced transmission by the A. albopictus mosquito(Schuffenecker et al. 2006). Since then, it has successively caused outbreaks in Africa, the Indian Ocean, South East Asia, the South America, and Europe (Zeller et al. 2016). 相似文献

In conclusion, the novel visual RT-LAMP assay is a simple, rapid, and sensitive approach for detection of SARS-CoV-2, and it is ready for application in primary care and community hospitals or health care centers, and even patients' own houses in response to the current SARS-CoV-2 epidemic because the assay does not require sophisticated equipment and skilled personnel. Furthermore, it is also ready to be used in fields for screening samples from wild animals and environments to facilitate the identification of potential intermediate hosts that mediate the cross-species transmission of SARS-CoV-2 from bats to humans. 相似文献
