Plastid evolution: remnant algal genes in ciliates.
Determination of the number of times that plastids have been gained and lost during eukaryotic evolution has proven difficult. A recent study has uncovered what could be the molecular signature of a photosynthetic ancestry for an important plastid-lacking lineage of microbial eukaryotes--the ciliates.
