Evidence for genetic recombination between Mycobacterium smegmatis strain Rabinowitchi (Rab) and strain Jucho or PM5 is presented. Backcrosses of recombinants by either parental strain indicated four different types of mating behavior, suggesting that the mycobacterial compatibilities are controlled by at least two different factors. No sex factor that transfers at a high frequency or that is s...
Begomoviruses (single-stranded DNA plant viruses) are responsible for serious agricultural threats. Begomovirus populations exhibit a high degree of within-host genetic variation and evolve as quickly as RNA viruses. Although the recombination-prone nature of begomoviruses has been extensively demonstrated, the relative contribution of recombination and mutation to the genetic variation of bego...
Recombination between RNA sequences plays a role in the fast evolution of a few viruses. There has been no report on hepatitis D virus (HDV) recombination. In this study, we analyzed genetic recombination of HDV and its possible impact on evolution and clinical course. The aligned HDV sequences allowed us to construct a phylogenetic tree which supported the notion of distinct lineages of HDV. T...
Background and Aims: Apricot latent virus (ApLV) is a species within Foveavirus genus (Betaflexiviridae family, Tymovirales order). Phylogenetic analyses using different ORFs nucleotide sequences divided most ApLV isolates into two clusters. However, there is little data about the sources of genetic differentiation among ApLV isolates. Materials and Methods: Partial coat protein (CP) sequences...
