Two types of differentially photo-regulated nuclear genes that encode sigma factors for chloroplast RNA polymerase in the red alga Cyanidium caldarium strain RK-1.


A nuclear gene, sigA, that encodes a sigma factor for chloroplast RNA polymerase has previously been identified and characterized in the primitive red alga Cyanidium caldarium strain RK-1. Southern hybridization analysis indicated the presence of two additional sigma factor genes, which have now been cloned and shown to encode virtually identical proteins… (More)
