Two homologues of INNER NO OUTER (INO) in Nymphaea alba and N. colorata (Nymphaeaceae) were isolated and the expression pattern of the N. alba INO homologue NaINO was examined by in situ hybridization. The INO homologues obtained have a portion similar to INO in the predicted amino acid sequences between the conserved zinc finger-like and YABBY domains. In an in situ hybridization analysis, NaINO is expressed in the outer epidermis of the outer integument, inner integument, and the tip of the nucellus. The pattern observed in the outer integument is very similar to that of Arabidopsis thaliana, while the expression in the inner integument and nucellus is not observed in A. thaliana.
