A gene, frxC, which is unique to the chloroplast genome of the liverwort Marchantia polymorpha, has sequence similarity to nifH, the product of which is an iron protein of a nitrogenase. Although frxC is expressed to produce a protein in liverwort chloroplasts, its function is not known. Using a probe of liverwort chloroplast DNA, a 10.1-kb region containing a gene cluster consisting of open reading frames (ORF278-frxC-ORF469-ORF248) was isolated from the cyanobacterium Synechocystis PCC6803. In this region, frxC and ORF469 showed sequence similarities to liverwort chloroplast frxC (83%) and immediately downstream ORF465 (74%), respectively. Synechocystis frxC showed 31% amino acid sequence identity with nifH1 from Clostridium pasteurianum. Additionally, Synechocystis ORF469 showed a sequence similarity (19% identity) to C. pasteurianum nifK product, which is the beta subunit of a molybdenum-iron protein of a nitrogenase complex. Conservation of the gene arrangement between liverwort and Synechocystis suggests that the liverwort chloroplast frxC-ORF465 cluster may have evolved from an ancestor common to Synechocystis, and that these two genes may have been transferred to the nuclear genome in tobacco and rice during evolution.
