Microscopic images of different tissues in 3.0–5.0 mm snails after BgAOX mRNA knockdown and AOX activity inhibition. Scale bar in black = 20 μm. A Sections from untreated snails, including the head-foot region (A1, A2), liver (A3), and ovotestis (A4) at 21 days. B Sections from RNAi-treated snails, including the head-foot region (B1, B2), liver (B3), and ovotestis (B4) at 21 days. C Sections from SHAM-treated snails, including the head-foot region (C1, C2), liver (C3), and ovotestis (C4) at 21 days.
