Characterization of Tomato yellow spot virus, a novel tomato-infecting begomovirus in Brazil
The objective of this work was the biological and molecular characterization of a begomovirus detected in São Joaquim de Bicas, Minas Gerais, Brazil, named TGV-[Bi2], by determining its host range, complete nucleotide sequence and phylogenetic relationships with other begomoviruses. Biological characterization consisted of a host range study using either sap inoculation or particle bombardment ...
متن کاملTomato yellow spot virus, a tomato-infecting begomovirus from Brazil with a closer relationship to viruses from Sida sp., forms pseudorecombinants with begomoviruses from tomato but not from Sida.
Geminiviruses are characterized by a circular, single-stranded DNA genome and twinned icosahedral particles. Begomoviruses (whitefly-transmitted geminiviruses) are a major constraint to crop production worldwide. In Brazil, tomato-infecting begomoviruses emerged as serious pathogens over the last 10 years, due to the introduction of a new biotype of the insect vector. Tomato yellow spot virus (...
متن کاملPhenotypic and Molecular Screening of Tomato Germplasm for Resistance to Tomato Yellow Leaf Curl Virus
Tomato yellow leaf curl virus (TYLCV) is a major tomato virus in tropical and subtropical regions. In this study, 134 accessions of Solanum lycopersicum and six accessions of Solanum peruvianum were assessed for resistance to an Iranian isolate of TYLCV. Plants were inoculated using whiteflies (Bemisia tabaci) and the reaction of plants was evaluated based on either disease symptoms or viral DN...
متن کاملA dramatic physiological and anatomical changes of tomato plants infecting with tomato yellow leaf curl germinivirus
This study was to investigate the changes of physiological and anatomical in tomato plants infected with tomato yellow leaf curl virus (TYLCV) isolate. it was found the growth characteristic, cell membrane stability index, photosynthetic pigment, carbohydrate contents and related to mineral ions contents of tomato plants. As were decreased, when compared with healthy plants. While electrical le...
متن کاملComplete Genomic Sequence of a Strain of Tomato Yellow Leaf Curl Virus from Iran
Background and Aims: Tomato yellow leaf curl virus (TYLCV) is one of the most destructive viruses of tomato that leads to reduced tomato yield up to 100% in tropical and subtropical regions. In this study, the complete sequence of TYLCV isolate from Hormozgan province, Iran and its recombination evsent was determined. Methods: TYLCV infected tomato was collected from Hormozgan province. Total D...
