Phased DNA sequences and aminoacids This file contains all the phased sequences used in the study, with heterozygous gaps resolved. Fasta containing aminoacids translations are also provided for markers used in MK tests. Phased_DNA_sequences_and_amino_acids.zip Informations about individuals This file contains for each individual included in the study its identifier, its color form/morph, the locality where it was sampled and its sex. Individual_information.xlsx, Studies on melanin-based color variation in a context of natural selection have provided a wealth of information on the link between phenotypic and genetic variation. Here, we evaluated associations between melanic plumage patterns and genetic polymorphism in the Réunion grey white-eye (Zosterops borbonicus), a species in which mutations on MC1R do not seem to play any role in explaining melanic variation. This species exhibits five plumage color variants that can be grouped into three color forms which occupy discrete geographic regions in the lowlands of Réunion and a fourth form which comprises two color morphs (grey and brown), occurs at high elevation, and represents a true color polymorphism. We conducted a comprehensive survey of sequence variation in 96 individuals at a series of seven candidate genes other than MC1R that have been previously shown to influence melanin-based color patterns in vertebrates, including genes that have rarely been studied in a wild bird species before: POMC, Agouti, TYR, TYRP1, DCT, Corin and SLC24A5. Of these seven genes, two (Corin and TYRP1) displayed an interesting shift in allele frequencies between lowland and highland forms and a departure from mutation-drift equilibrium consistent with balancing selection in the polymorphic highland form only. Sequence variation at Agouti, a gene frequently involved in melanin-based pigmentation patterning, was not associated with color forms or morphs. Thus, we suggest that functionally important changes in loci other than those classically studied may beare involved in the color polymorphism exhibited by the Réunion grey white-eye and possibly many other non-model species., Peer reviewed
