Summary Viroid infection often leads to early flowering in the host plant. This report describes the targeting of the FRIGIDA‐like protein 3 (FRL3) mRNA in tomato plants by a small RNA derived from the conserved left terminal region of the potato spindle tuber viroid (PSTVd). This targeting leads to...
