Nucleotide sequence and genome organization of tomato leaf curl geminivirus.
The genome of tomato leaf curl virus (TLCV) from Australia was cloned and its complete nucleotide sequence determined. It is a single circular ssDNA of 2766 nucleotides containing the consensus nonanucleotide sequence present in all geminiviruses. It has six open reading frames with an organization resembling that of certain other dicotyledonous plant-infecting monopartite geminiviruses, i.e. t...
متن کاملComplete nucleotide sequence of the geminivirus tomato yellow leaf curl virus, Thailand isolate.
The complete genome of a Thailand isolate of the geminivirus tomato yellow leaf curl virus (TYLCV-Th) has been cloned and the nucleotide sequence determined. The genome consists of two DNAs each slightly greater than 2700 nucleotides in length and designated A-DNA and B-DNA. The A-DNA contains six open reading frames (ORFs) capable of encoding proteins with M(r)s greater than 10K; two ORFs were...
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 کاملTomato dwarf leaf curl virus, a new bipartite geminivirus associated with tomatoes and peppers in Jamaica and mixed infection with tomato yellow leaf curl virus
Genomic characterization using nonradioactive probes, polymerase chain reaction with degenerate primers for whitefly transmitted geminiviruses and nucleotide sequencing were used to describe a new bipartite geminivirus, associated with dwarfing and leaf curling of tomatoes and peppers in Jamaica. Partial DNA-A and DNA-B clones were obtained. DNA sequence analysis showed that tomato and pepper s...
متن کاملTomato leaf curl geminivirus from India has a bipartite genome and coat protein is not essential for infectivity.
Genomes of two isolates of tomato leaf curl geminivirus from India (ToLCV-India) have been sequenced. ToLCV-India contains A and B components, both of which are required for systemic movement and symptom development. The two isolates have 94% sequence identify but one isolate gave mild symptoms in Nicotiana benthamiana and tomato. The genome organization of ToLCV-India is similar to other white...
