Beware: this locus could accidentally be confused with the act1 (actin 1) locus, which also was called MAc1 in past publications!. (was lar*-487) several archesporial cells undergo normal meiosis; plants partially female sterile but completely male sterile. Genetic 2005 10 coordinates determined from these recombination and map data: mac1 -12- T9-10b; mac1 TB-10Sc; oy1 -8- mac1; see MaizeGDB ID:133664; 105340; 230282. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
