ABSTRACT
Cryptophytes are unicellular eukaryotic algae that
acquired photosynthesis secondarily through the
uptake and retention of a red-algal endosymbiont.
The plastid genome of the cryptophyte Rhodomo-
nas salina CCMP1319 was recently sequenced and
found to contain a genetic element similar to a
group II intron. Here, we explore the distribution,
structure and function of group II introns in the
plastid genomes of distantly and closely related
cryptophytes. The predicted secondary structures
of six introns contained in three different genes
