“…At the same time, however, several genes in this region of chromosome I display polymorphisms including AGO3 . Phylogenetically, AGO3 is the closest homolog to AGO2 , yet except against BaMV, AGO3 has not been found to be involved in virus resistance (Jaubert et al , ; Brosseau & Moffett, ; Garcia‐Ruiz et al , ; Brosseau et al , ; Alazem et al , ), but rather appears to play a role in DNA methylation (Zhang et al , ). Moreover, although AGO3 exhibits some polymorphisms, in silico analysis revealed no correlation between any of these polymorphisms and PVX susceptibility (Table S5b).…”
