Description:

Plagioselmis prolonga has an unusual nucleomorph genomic structure, in that it lacks the ribosomal cistrons thought to be at the ends of all nucleomorph chromosomes. Based on its distant relationship to the only cryptomonad which has had its necleomorph genome sequenced, Guillardia theta, we expect the nucleomorph of P. prolonga to help elucidate the mechanisms behind genome reduction following secondary endosymbiosis.
