Plant Biology. In the article “Mitochondrial localization of a NADR-dependent isocitrate dehydrogenase isoenzyme by using the green fluorescent protein as a marker” by Susana Gálvez, Odile Roche, Evelyne Bismuth, Spencer Brown, Pierre Gadal, and Michael Hodges, which appeared in number 13, June 23, 1998, of Proc. Natl. Acad. Sci. USA (95, 7813–7818), the abbreviation NADP incorrectly appeared as NADR due to a printer’s error. The correct title is: Mitochondrial localization of a NADP-dependent isocitrate dehydrogenase isoenzyme by using the green fluorescent protein as a marker.
