A nuclear genome assembly of an extinct flightless bird, the little bush moa

<p>We present a draft genome of the little bush moa (<em>Anomalopteryx didiformis</em>) - one of approximately nine species of extinct flightless birds from Aotearoa, New Zealand - using ancient DNA recovered from a fossil bone from the South Island. We recover a complete mitochondrial genome at 249.9X depth of coverage and almost 900 Mb of a male moa nuclear genome at ~4-5X coverage, with sequence contiguity sufficient to identify more than 85% of avian universal single-copy orthologs. We describe a diverse landscape of transposable elements and satellite repeats; estimate a long-term effective population size of ~240,000; identify a diverse suite of olfactory receptor genes and an opsin repertoire with sensitivity in the UV range; show that the wingless moa phenotype is likely not attributable to gene loss or pseudogenization; and identify potential function-altering coding sequence variants in moa that could be synthesized for future functional assays. This genomic resource should support further studies of avian evolution and morphological divergence.</p>

Data from: Gradual evolution towards flightlessness in Steamer-Ducks

Flightlessness in birds is the product of changes in suites of characters--including increased body size and reduced anterior limbs--that have evolved repeatedly and independently under similar ecological conditions (generally insularity). It remains unknown whether this phenotypic convergence extends to the genomic level, partially because many losses of flight occurred long ago (such as in penguins or ratites), thus complicating the study of the genetic pathways to flightlessness. Here we use genome sequencing to study the evolution of flightlessness in a group of ducks that are current and dynamic exemplars of this major functional transition. These recently diverged Tachyeres steamer-ducks differ in their ability to fly: one species is predominantly flighted and three are mainly flightless. Through a genome-wide association analysis we identify two narrow candidate genomic regions implicated in the morphological changes that led to flightlessness, and reconstruct the number of times flightnesses has evolved in Tachyeres. The strongest association is with DYRK1A, a gene that when knocked-out in mice leads to alterations in growth and bone morphogenesis. These findings, together with phylogenetic and demographic analyses, imply that the genomic changes leading to flightlessness in Tachyeres may have evolved once, and that this trait remains functionally polymorphic in two species.
