Natural recombination between Tomato yellow leaf curl virus-is and Tomato leaf curl virus.
The complete genome sequences (2791 and 2793 nt) of isolates of Tomato yellow leaf curl virus-Is (TYLCV-Is) from Spain (SP72/97) and Portugal (Port2/95) were determined. These isolates are closely related to TYLCV-Is isolates reported in Japan (Japan-A and Japan-S) and Israel (Israel/Mild). Comparison of all sequenced isolates of TYLCV-Is showed that part of the genome comprising the intergenic...
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 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...
متن کاملGenetic structure and population variability of tomato yellow leaf curl China virus.
Geminiviruses have circular single-stranded DNA genomes and are important pathogens in tropical and subtropical regions, but their population diversity and variability are poorly understood. Here, we have investigated variations accumulating in Tomato yellow leaf curl China virus (TYLCCNV), a geminivirus in the genus Begomovirus of the family Geminiviridae. The population variation was analyzed...
متن کاملA DNAbeta associated with Tomato yellow leaf curl China virus is required for symptom induction.
We report here that all 25 isolates of Tomato yellow leaf curl China virus (TYLCCNV) collected from tobacco, tomato, or Siegesbeckia orientalis plants in different regions of Yunnan Province, China, were associated with DNAbeta molecules. To investigate the biological role of DNAbeta, full-length infectious clones of viral DNA and DNAbeta of TYLCCNV isolate Y10 (TYLCCNV-Y10) were agroinoculated...
