Description Missing PSI thylakoid membrane core complex; seedling slightly pale green. Like hcf44, but not allelic to hcf44 (Miles D. unpublished). Green seedling leaves; primary deficiency in photosystem I core complex (Miles et al. 1979). TB-1Lc, TB-4L-1L and TB-5S-1L uncover. EM freeze fracture shows reduction in PF particles of unstacked thylakoid membranes (Miller 1980). Somewhat reduced photosystem II activity, 80% reduced photosystem I activity, 80% reduced ATP synthesis, 95% reduced CO2-fixation (Miles 1980, 1982; Miles and Metz 1985). Classification: hcf trait, excellent. Viability: seedling lethal at 3- to 4-leaf stage. (Polacco). Genetic 2005 1 coordinates determined from these recombination and map data: hcf50 T1-4(4692)(1); hcf50 T1-5(8041)(1)[source of data unclear]; TB-1Lc(1) hcf50; see MaizeGDB ID:104699; 104700; 104701. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
