Abstract：
:Nucleomorphs are the vestigial nuclear genomes of eukaryotic algal cells now existing as endosymbionts within a host cell. Molecular investigation of the endosymbiont genomes has allowed important insights into the process of eukaryote/eukaryote cell endosymbiosis and has also disclosed a plethora of interesting genetic phenomena. Although nucleomorph genomes retain classic eukaryotic traits such as linear chromosomes, telomeres, and introns, they are highly reduced and modified. Nucleomorph chromosomes are extremely small and encode compacted genes which are disrupted by the tiniest spliceosomal introns found in any eukaryote. Mechanisms of gene expression within nucleomorphs have apparently accommodated increasingly parsimonious DNA usage by permitting genes to become co-transcribed or, in select cases, to overlap.
