Affects photophosphorylation; yellow-green seedling, may survive. Like hcf1. TB-1Sb-2L4464 uncovers; probably not uncovered by TB-1Sb; not allelic to hcf1, hcf3 (Leto and Miles 1977, 1979; Leto 1982; Miles et al. 1985). Fluorescence induction kinetics class IV, yellow-green seedling and deficient in photophosphorylation (Miles 1980, 1982). (Polacco). Not allelic to hcf1 or hcf3. Genetic 2005 2 coordinates determined from these recombination and map data: T1-2(4464) hcf15; see MaizeGDB ID:104672. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
