Abstract

Faba bean necrotic yellows virus (FBNYV) causes severe yield losses and crop failure in legumes in the north African, south Asian and European countries. Following nucleotide sequencing of DNA-M segment of 17 host and geographical FBNYV isolates in Iran, different molecular analysis were performed based on all available DNA-M sequences of FBNYV. Based on constructed Phylogenetic tree using nucleotide sequence of DNA-M component, FBNYV isolates were grouped into three clades, including isolates from Iran and Azerbaijan as a distinct clade. Genetic distance studies of FBNYV host subpopulations revealed some evidences of Host adaptation in FBNYV natural selection. High gene flow was found among Iran – Azerbaijan and Spain – Africa subpopulations, indicating the relationship of their origins. Maximum genetic diversity of DNA-M was estimated in the central subpopulation of Iran. The dN/dS (Ѡ ) value less than 1 represented the Negative selection pressure on the movement protein of the virus. Seven out of nine recombination events were detected in DNA-M of Iranian FBNYV isolates. This is the first report of the FBNYV infection on pea from Iran. In the current study, the complete DNA-M nucleotide sequences of French bean and pea isolates of FBNYV were determined for the first time in the world.
