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.
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.
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.
Functional recapitulation of a likely evolutionary gain in gene expression shows that two genes are sufficient to switch mesoderm cell internalization from stochastic cell ingression to coordinated epithelial invagination.
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.
