Upregulation of Piezo2 and downregulation of TRPV1 and TRPM8 in duck TG. (A) Gene expression ratio between TG and DRG based on differential transcriptome analysis of domestic duck (d., three animals) and chicken (ch., two animals) tissues. (B–F) RNA in situ hybridization analysis of Piezo2, TRPV1, and TRPM8 expression in TG and DRG from tactile foragers and nonspecialist birds. Shown are representative RNA in situ hybridization images and quantitative analyses of cells within TG and DRG expressing indicated transcripts. (Scale bar, 100 µm.) c, coot; ch, chicken; d, domestic duck; mal, mallard; ph, pheasant; sh, shoveller. Data are shown as mean ± SEM from ≥1,400 cells from ≥8 tissue sections. ****P < 0.0001, two-tailed t test.
