(A) UMAP plots of pigment cells colored by expression of xanthophore cluster-enriched genes (bco1, bco2b, bscl2l, slc2a11b, slc22a7a, wu:fc46h12). (B) Expression in xanthophores of genes shown in A, as revealed by whole-mount in situ hybridization patterns corresponding to those of known xanthophore lineage markers and localization of differentiated and cryptic xanthophores (Hamada et al., 2014; Lang et al., 2009; McMenamin et al., 2014; Parichy et al., 2000b). Insets show at higher magnification blue-stained cells of xanthophore lineage. Bars at right indicate cell positions relative to anatomy of final pattern: solid black, melanophores in prospective stripe regions; dashed black, melanophores transiently located in prospective interstripe region; light yellow, xanthophores likely to remain cryptically (unpigmented) within stripes; orange, xanthophores likely to develop pigmentation in the interstripe.
