Insights

Researchers sequenced the complete genome of Rice tungro bacilliform virus (RTBV) from Malaysia, nearly two decades after the first isolate was sequenced. This provides updated genomic information for this important plant pathogen.

Area of Science:

  • Plant Virology
  • Genomics
  • Molecular Biology

Background:

  • Rice tungro disease has been endemic in Malaysia since the 1930s.
  • The initial genome sequence of Rice tungro bacilliform virus (RTBV) from Malaysia was established in 1999.
  • No new RTBV genome sequences from Malaysia have been reported for nearly 20 years.

Purpose of the Study:

  • To present the complete genome sequence of a contemporary RTBV isolate from Malaysia.
  • To update the genomic information available for RTBV in the region.
  • To facilitate future research on RTBV evolution and epidemiology.

Main Methods:

  • Whole-genome sequencing of an RTBV isolate from rice.
  • Bioinformatic analysis of the obtained genome sequence.

Main Results:

  • The complete genome sequence of an RTBV isolate from Seberang Perai, Malaysia, was successfully determined.
  • This represents the first RTBV genome sequence from Malaysia reported in almost two decades.

Conclusions:

  • The availability of this new genome sequence provides valuable contemporary data for RTBV research in Malaysia.
  • This finding aids in understanding the genetic diversity and evolution of RTBV.

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Genome Size and the Evolution of New Genes03:21

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
