1Bemisia tabaci Phylogenetic Groups in India and the Relative Transmission Efficacy of Tomato leaf curl Bangalore virus by an Indigenous and an Exotic Population显示文摘Bemisia tabaci adults from various host-plant species were collected from 31 regions across India.266 B.tabaci samples were first screened by RAPD-PCR to examine molecular variability and to select individuals with different fingerprints.Host-plant and region of collection were then used to select 25 individuals for PCR amplification and sequencing of their partial mitochondrial cytochrome oxidase subunit one(mtCOI)genes.Pairwise comparisons with mtCOI consensus sequences showed that the majority of these samples had <3.5% sequence divergence from groups currently termed Asia I,Asia II-5,Asia II-7,and Asia II-8.The biotype-B B.tabaci from India clustered into the Middle East-Asia Minor 1 group.A new group of B.tabaci from Coimbatore,collected from pumpkin,was related most closely to the Asia I group(6.2% sequence divergence from the consensus Asia I sequence).To increase our understanding of the epidemiology of tomato leaf curl disease(ToLCD)and the key B.tabaci genetic groups involved in virus spread,the indigenous Asia I and the exotic biotype-B population from South India were used to carry out transmission experiments using Tomato leaf curl Bangalore virus(ToLCBV).The acquisition access periods(AAP),inoculation access periods(IAP),latent periods(LP),and ToLCBV transmission efficiencies of the two populations were compared and the biotype-B had the more efficient transmission characteristics.These results are discussed in relation to recent changes in the epidemiology of tomato leaf curl disease in South India.R V Chowda-Reddy M Kirankumar Susan E Seal V Muniyappa Girish B Valand M R Govindappa John Colvin 2012Journal of Integrative Agriculture2012,11,2:8
2Infiltrating adenocarcinoma arising in a villous adenoma of the anal canal显示文摘Primary neoplasms arising in the anal canal are relatively unusual.In particular, adenomas and adenocarcinomas are distinctly rare entities in this region.We describe an infiltrating, well-differentiated adenocarcinoma arising in a villous adenoma from the distal anal canal, in an otherwise healthy patient at low risk for gastrointestinal malignancy.This is the case of an octogenarian man with a several year history of hemorrhoids and intermittent rectal bleeding, more recently complaining of continuous hematochezia.Examination revealed a blood-covered pedunculated mass with a long stalk protruding from the anus.The lesion was amputated at the bedside.Microscopic evaluation revealed an infiltrating well-differentiated adenocarcinoma, arising from a villous adenoma.This was further evaluated under anesthesia and complete excision of distal anal tissue was performed.Our report is the f irst describing the possible malignant degeneration of a villous adenoma in the anal canal.Marni Colvin Aris Delis Erika Bracamonte Hugo Villar Luis R Leon Jr 2009World Journal of Gastroenterology2009,15,28:2
