Bentz et al. explore the origins of recombination suppression between ancestral autosomes leading to independent sex chromosome formation in Asparagus.
Gatts et al. find a clustered set of proteins with strong signatures of evolutionary rate covariation with plastid proteostasis components, forming a functional module within a plant protein–protein interactome network.
Hale et al. analysed >500 grass genomes to support a “stable motifs, variable binding sites” model of cis-regulatory evolution that involves turnover of thousands of individual binding sites while preserving TF binding preferences.
