Affects electron transport; green seedling. Yellow-green seedling, with undefined block in electron transport and photophosphorylation, fluorescence class IV (Miles 1980, 1982). TB-6Lc uncovers (Miles et al. 1985). Classification: hcf trait, very good; reduced leaf pigmentation, very good. (Polacco). Genetic 2005 6 coordinates determined from these recombination and map data: TB-6Lc(6) hcf36; see MaizeGDB ID:104687. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
