(Submitter supplied) In crown group tetrapods, individual digits are homologized in relation to a pentadactyl ground plan. However, testing hypotheses of digit homology is challenging because it is unclear whether digits develop with distinct and conserved gene regulatory states. Here we show dramatic evolutionary dynamism in the gene expression profiles of digits, challenging the notion that five digit identities are conserved across amniotes. more...

(Submitter supplied) Birds and other reptiles possess a diversity of feather and scale-like skin appendages. Feathers are commonly assumed to have originated from ancestral scales in theropod dinosaurs. However, most birds also have scaled feet, indicating birds evolved the capacity to grow both ancestral and derived morphologies. This suggests a more complex evolutionary history than a simple linear transition between feathers and scales. more...

(Submitter supplied) Previous studies examining the reproductive health of alligators in Florida lakes indicate that a variety of developmental and health impacts can be attributed to environmental quality and exposures to environmental contaminants. A number of these environmental contaminants have been shown to disrupt normal endocrine signaling. The potential that these environmental toxicants may influence epigenetic status and correlate to the health abnormalities was investigated in the current study. more...

(Submitter supplied) The array used for the differential methylation analysis was a DNA methylated custom array by Roche Nimblegen that consisted of a Whole Genome Tiling Array of the American Alligator (Alligator mississippiensis) made of two chip set arrays with a 200bp resolution (121211-allmis-ms-meth-ux1). Probe sizes were 50-75mer in length and median probe spacing was 200bp. The December 2014 report of the Alligator mississippiensis genome produced by the Genome Sequencing Center was retrieved (http://crocgenome.hpc.msstate.edu/crocbase/gbrowsers.html, http://crocgenome.hpc.msstate.edu/gb2/gbrowse/gator/). more...
