This study examines nonadditive gene expression and homoeolog expression bias in hexaploid wheat hybrids, finding widespread nonadditive expression and altered homoeolog balance linked to parental divergence and gene body methylation.

This study shows that homoeolog expression bias in hexaploid wheat is reprogrammed and stabilized within a few generations, varying based on parental lines.

The paper uses methylomes to infer demographic histories in Arabidopsis thaliana and Brachypodium distachyon, finding that methylation variants reveal recent population expansions not detectable with SNPs.

This study shows that Drosophila populations under high parasite pressure evolved constitutive humoral immunity and enhanced induced immune responses, with Upd3 and JAK/STAT signaling playing key roles.
