Nucleotide sequence of capsid protein gene of rice tungro bacilliform virus

Archives of Virology, 1992
The sequence of 5,028 nucleotides, including one open reading frame (ORF), of rice tungro bacilliform virus (RTBV) dsDNA was determined. The predicted translational product comprises 1,675 amino acids and has Mr of 194,134 (p194). The amino acid sequences of three tryptic fragments from the 32 k capsid protein of RTBV (p32) were found in the predicted ...

The molecular diversity and evolution of Rice tungro bacilliform virus from Indian perspective

Virus Genes, 2012
Rice tungro disease is caused by a combination of two viruses: Rice tungro spherical virus and Rice tungro bacilliform virus (RTBV). This study was performed with the objective to decipher the molecular variability and evolution of RTBV isolates present in the tungro-affected states of Indian subcontinent.

Specificity of a promoter from the rice tungro bacilliform virus for expression in phloem tissues

Plant Journal, 1993
The major promoter region for the transcription of the genome of rice tungro bacilliform virus (RTBV), a newly described badnavirus, has been identified. Fragments of the RTBV genome upstream of the site of transcription initiation were isolated and tested for promoter activity using a β‐glucuronidase reporter gene (gusA).

Genetic Diversity of the Coat Protein Gene of Rice Tungro Bacilliform Virus in the Philippines

Philippine Journal of Science, 2020
Rice tungro is one of the most economically damaging virus diseases in the Philippines, which is caused jointly by Rice tungro bacilliform virus (RTBV) and Rice tungro spherical virus (RTSV). The disease causes a significant effect on rice propagation and cultivation.

Variation of Rice Tungro Viruses: Further Evidence of Two Rice Tungro Bacilliform Virus Strains and Possibly Several Rice Tungro Spherical Virus Variants

Journal of Phytopathology, 1998
AbstractRice tungro disease is caused by two viruses: rice tungro spherical virus (RTSV) and rice tungro bacilhform virus (RTBV). Our results obtained using polymerase chain reaction (for RTBV) and western blot analysis (for RTSV) to study the epidemiology of tungro supported earlier studies that two RTBV strains.

Assessment of resistance to rice tungro disease in popular rice varieties in India by introgression of a transgene against Rice tungro bacilliform virus

Archives of Virology, 2019
Rice crops in South and Southeast Asian countries suffer critical yield losses due to rice tungro disease caused by joint infection with rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV). Previously, for generating RNA interference-based transgenic resistance against tungro viruses, RTBV ORF IV was used as a transgene to ...

Inheritance of tolerance to rice tungro bacilliform virus (RTBV) in rice (Oryza sativa L.)

Theoretical and Applied Genetics, 1990
From a large number of rice varieties tested, no variety was identified as resistant to tungro bacilliform virus (RTBV). Only in Utri Merah was the RTBV multiplication restrictive, whereas other varieties such as Kataribhog and Pankhari 203 were identified as tolerant. These varieties were crossed with a susceptible variety.

Molecular analysis of two complete rice tungro bacilliform virus genomic sequences from India

Archives of Virology, 2002
The complete genomic sequences of two geographically distinct isolates of rice tungro bacilliform virus (RTBV) from India were determined. Both the sequences showed equal divergence from previously reported Southeast Asian isolates. Numerous insertions, deletions and substitutions, mostly in the intergenic regions, were found.

Replication Intermediates of Rice Tungro Bacilliform Virus DNA Support a Replication Mechanism Involving Reverse Transcription

Virology, 1994
Rice tungro bacilliform virus (RTBV) replication intermediates have been studied in rice plants infected with the virus. Unencapsidated virus-specific molecules were identified which had open circular, linear, supercoiled (SC), strong-stop, single-stranded, linear double-stranded hairpin, and double-stranded with single-stranded extension DNA forms ...

The large intergenic region of Rice tungro bacilliform virus evolved differentially among geographically distinguished isolates

Virus Genes, 2011
Rice tungro bacilliform virus (RTBV) is a plant pararetrovirus. The large intergenic region (LIGR) of RTBV having a single transcriptional promoter produces more than genome length pregenomic RNA (pgRNA) which directs synthesis of circular double-stranded viral DNA and serves as a polycistronic mRNA.
