5 cze 2023 · According to the evolutionary relationships between hallmark viral genes, plant viruses are classified into two realms, Monodnaviria and Riboviria, which include single-strand DNA (ssDNA) viruses and RNA viruses, respectively.
More recently virus research has been focused on understanding the genetics and molecular biology of plant virus genomes, with a particular interest in determining how the virus can replicate, move and infect plants.
21 paź 2011 · DNA-B encodes two genes required for plant virus movement: BC1, movement protein (cell to cell); BV1, nuclear shuttle protein. C, complementary-sense open reading frames (ORFs); V, virus-sense ORFs. Black box, location of the nucleotide sequence common to both genomic components. Light grey boxes designate ORFs.
1 sty 2020 · Viruses are classified into six major groups based on nature and genome organization as double-stranded DNA (dsDNA), single-stranded DNA (ssDNA), dsRNA, reverse-transcription (RT) viruses, negative-sense ssRNA (–ssRNA) and positive-sense ssRNA (+ssRNA) viruses.
12 wrz 2022 · Plant viruses encode genomes that consist of single-stranded (ss) or double-stranded (ds) DNA or RNA segment(s) with positive-, negative-, or ambisense polarity (Koonin et al. 2021). The genetic material of plant viruses is generally encapsidated in virions by capsid protein(s) (Callaway et al. 2001). Due to the limited coding capacity, plant ...
24 gru 2022 · DNA viruses belong to either Group I (double-stranded DNA; dsDNA) or Group II (single-stranded DNA; ssDNA) of the Baltimore classification system for viruses. Single-stranded DNA is usually expanded to double-stranded in infected cells.
16 lip 2019 · A network of shared genes between plant viruses and other viruses. In the network, virus genera are represented with nodes of different sizes depending on the number of sequences in the database.
