Tannier, @damdevienne.bsky.social et al. simulated horizontal gene transfer (HGT) with ghost lineages, finding that, when only 1% of potential donors are sampled, ca. 50% of SPR-inferred HGTs misidentify donors.

HGTs are not SPRs: In the Presence of Ghost Lineages, Series of Horizontal Gene Transfers do not Result in Series of Subtree Pruning and Regrafting
Abstract. When a gene is horizontally transferred (HGT), under the “replacement” model where the transferred gene replaces its homolog in the recipient gen

Mérel et al. use WGS data from 77 Drosophila species, finding that genome size and TE content correlate with relaxed selection, especially in GC-poor genes.

In 2010 (SMBE Lyon) I gave a talk about the impact of GC-biased gene conversion (gBGC) on functional sequence evolution. I argued that, because gBGC promotes G and C alleles irrespective of their fitness effect, it should generate some genetic load. 1/5
