The chloroplast NADH dehydrogenase F (ndhF) gene is found in all vascular plant divisions and is highly conserved. Its DNA fragment resides in the small single-copy region of the chloroplast genome, and is thought to encode a hydrophobic protein containing 664 amino acids and to have a mass of 72.9 kDa. [1]
The ndhF fragment has been a very useful tool in phylogenetic reconstruction at a number of taxonomic levels. [2] [3] [4] [5]
