Abstract
Significance INO80 is an evolutionarily conserved protein in eukaryotes. Mutations of INO80 cause growth arrest and embryo mortality in fruit flies and mice, which limits the investigation of INO80 biological functions during morphogenesis of multicellular organisms. Here, we show that AtINO80 interconnects with a light signaling pathway in Arabidopsis plants. Our characterization of atino80 mutants uncovers critical roles of INO80 in nucleosome density and H2A.Z incorporation during plant photomorphogenesis.
