and energy production genes. the genome lacks large inverted repeats commonly found in chloroplast. although a. lagunensis is similar to a. anophagefferens, it contains five chloroplast genes psaf, ycf45 and light independent chlorophyll biosynthesis genes chll, chln, and chlb which are not present in a. anophagefferens’ chloroplast genome. it is speculated that the presence of the light independent genes for chlorophyll biosynthesis is what allows a.lagunensis to persist in low light intensities.
