Recombination patterns in dicot-infecting mastreviruses mirror those found in monocot-infecting mastreviruses.


PMID 21484422

Abstract

Recombination has profoundly shaped the evolution of viruses in the family Geminiviridae and has been studied extensively in the two best characterised geminivirus lineages: the dicotyledonous plant infecting begomoviruses and the monocotyledonous plant infecting mastreviruses. Here, we demonstrate that the sizes and distributions of recombination events detectable within the members of a third major geminivirus lineage--the dicotyledonous plant infecting mastreviruses--are very similar to those of the monocot-infecting mastreviruses. This suggests that, despite host range differences, very similar biochemical, ecological and evolutionary factors must underlie recombination patterns in the dicot- and monocot-infecting mastreviruses.
