siRNA bodies are specific cytoplasmic foci in Arabidopsis thaliana which contain accumulated AGO7, SGS3 and RDR6. siRNA ibodies are distinct from P-bodies, but become positive to stress granule markers under stress induced translational repression, implying that siRNA bodies may store stalled mRNAs (22327216).
