abstract：:In Arabidopsis thaliana, Argonaute1 (AGO1) interacts with miR168 to modulate the small RNA regulatory pathway. However, the underlying mechanism of regulation and relationship between AGO1 and miR168 is poorly understood in the cash crop Solanum lycopersicum (tomato). We previously found that SlAGO1A and SlAGO1B were ...
