Molecular early burst associated with the diversification of birds at the K-Pg boundary

J. S. Berv, S. Singhal, D. J. Field, N. Walker-Hale, S. W. McHugh, J. R. Shipley, E. T. Miller, R. T. Kimball, E. L. Braun, A. Dornburg, C. T. Parins-Fukuchi, R. O. Prum, B. M. Winger, M. Friedman, S. A. Smith

The paper identifies a molecular early burst in avian evolution around the K-Pg boundary, linked to shifts in substitution rates and allometric scaling relationships.

Evolutionary blocks to anthocyanin accumulation and the loss of an anthocyanin carrier protein in betalain-pigmented Caryophyllales

B. Pucker, N. Walker-Hale, W. C. Yim, J. C. Cushman, A. Crumm, Y. Yang, S. Brockington

This study investigates the evolutionary mechanisms behind the loss of anthocyanin pigmentation in betalain-pigmented Caryophyllales by analyzing gene expression and duplication patterns in flavonoid pathway genes.

Characterizing gene tree conflict in plastome-inferred phylogenies

J. F. Walker, G. W. Stull, N. Walker-Hale, O. M. Vargas, D. A. Larson

The paper examines gene tree conflict in plastome-inferred phylogenies and identifies rpoC2 as a superior marker for angiosperm phylogeny reconstruction.
