Abstract

ABSTRACT An ultrastructural study of nucleomorphs in species of Cryptophyceae revealed aspects of division not previously reported, including the formation of a structured fibrous system, which accompanies the ordered alignment, duplication and separation into two groups of the densely staining particles typically characteristic of each nucleomorph. Despite reports indicating the presence of nucleic acids in the nucleomorph, the division process appears to be unlike any known form of nuclear division. However, the possibility exists that the nucleomorph represents the nucleus of a primitive ancestral red algal endosymbiont displaying a form so antique that its nuclear division bears no resemblance to any other known form of mitotic division.
