Gene Name high chlorophyll fluorescence 7 
Synonyms (4)

Chromosome No. 1
Gene Type Not classified
Has Phenotype not curated
Description Defective processing of 16S rRNA. Pigmentation near normal due to normal accumulation of light harvesting complexes. Deficient in many thylakoid membrane proteins. Yellow green seedling, reduced levels of electron transport and photophosphorylation, fluorescence induction kinetics class IV (Miles 1980, 1982). Phenotype is dosage dependent and cold-sensitive. Severe reduction in processing at 16S rRNA; uncovered by TB-1La (Barkan E. personal communication). Global defects in chloroplast protein synthesis (Taylor et al. 1987). Phenotype is dosage dependent and cold-sensitive. Classification: hcf trait, very good; yellow-green leaf trait, excellent. Viability: seedling lethal at 3- to 4-leaf stage. (Polacco). This locus shows a dosage effect. Plants hemizygous for hcf7 are more severely affected than homozygous hcf7 individuals. Temperature affects the severity of the phenotype. Plants at lower temperatures are more severely affected. Genetic 2005 1 coordinates determined from these recombination and map data: TB-1La hcf7; see MaizeGDB ID:142119. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
