Characterizing Hox genes in mayflies (Ephemeroptera), with Hexagenia limbata as a new mayfly model

open access: yesEvoDevo, 2022
Background Hox genes are key regulators of appendage development in the insect body plan. The body plan of mayfly (Ephemeroptera) nymphs differs due to the presence of abdominal appendages called gills.
