Extended Data Fig. 8: Transcript distribution in the birds’ pecten and anole conus.
From: Oxygen-free metabolism in the bird inner retina supported by the pecten
a,c,e,g,i,k,m,o,q,s,u,x, Tissue sections of zebra finch (n = 4), pigeon (n = 1), chicken (n = 1), and green anole (n = 1) eyes colour-coded for expression of the glucose transporter GLUT1 (SLC2A1; a,g,m,s), monocarboxylate transporter MCT1 (SLC16A1; c,i,o,u) and carbonic anhydrase 4 (CA4; e,k,q,x). Expression levels represent unitless variance-stabilized expression values, adjusted for sequencing depth across spots. b,d,f,h,j,l,n,p,r,t,v,y, Violin plots showing variance-stabilized expression levels across gene-expression spots covering the pecten (birds) or conus (anole) (red) and the neural retina (yellow) for the corresponding genes. Note that panels for the zebra finch in a-f are from Fig. 3 and are included here for comparison with pigeon, chicken, and anoles.
