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 that are homologous to eubacterial sigma factors. These genes, which are also present in the nuclear genome, have therefore been named sigB… CONTINUE READING
