Electrophoretic mobility; plastidial; monomeric. Genetic 2005 10 coordinates determined from these recombination and map data: glu1 -1- sad1; glu1 -0.4- sad1; umc64a -3- sad1 -9- mgs1; see MaizeGDB ID:60744; 60745; 754917. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
