The dual-action evolutionarily conserved NatB catalytic subunit NAA20 regulates poplar root development in response to salt and osmotic stresses.

Abstract

In Populus simonii, the N-terminal acetyltransferase subunit gene PsiNAA20 was induced by salt stress and osmotic stress and regulates root development. The spatiotemporal specificity of PsiNAA20-interacting gene expression and translation efficiency suggested dual functions in poplar root development under salt stress and osmotic stress.
