AGO1 and fungal infectious disease: In the present study, aiming to identify and uncover the functions of V. dahliae sRNA (VdsRNA) classes associated with host AGO1 protein during fungal infection, we immunoprecipitated AGO1 using the c-myc antibody from 6myc-AGO1-overexpressing Arabidopsis plants (6myc-AGO1) with or without V. dahliae infection.
