The maintenance DNA methyltransferase DNMT1 is required for the transition of spermatogonia to spermatocytes both during larval testis development and adult sperm replenishment in the insect Oncopeltus fasciatus.

During the evolution of insect lineages, a signaling pathway dedicated to pathogen defense was co-opted for a new role in embryonic patterning.

mille-pattes micropeptides have conserved function in insect embryonic patterning together with transcription factor Shaven-baby and ubiquitin ligase Ubr3, except in flies wherein restoring broad embryonic Svb expression restores patterning potency.

CenH3, the defining component of centromeres in almost all eukaryotes, was independently lost in four insect lineages that transitioned from monocentricity to holocentricity.

The maize CLAVATA receptor, FEA2, functions in the perception of two different ligands, and remarkably that signaling from these different inputs is differentiated by the receptor interacting with two different downstream components.

Crucial functions of Toll signalling during dorsoventral axis formation might have evolved convergently in flies and crickets.

Hypotheses on brain homologies between insects and vertebrates are tested by comparing gene expression patterns from flies and beetles with those from vertebrates at early neuroectoderm stages.

Temperature-dependent fasciation mutants of Arabidopsis unexpectedly connect mitochondrial RNA processing to the control of cell proliferation during lateral root morphogenesis via electron transport chain activity and reactive oxygen species production.

Pair-rule genes in the wasp Nasonia function as in Drosophila in patterning anterior segments, and similar to ancestral insects in patterning posterior segments, illustrating a mixed-mode transition state between short and long germ embryogenesis.
