Naegleria gruberi, a free-living protist, has long been treasured as a model for basal body
and flagellar assembly due to its ability to differentiate from crawling amoebae into …

Plasmodial slime molds are members of the class Amoebozoa forming elaborate fruit bodies
releasing airborne spores. Two species concepts have been developed independently: a …

In addition to splicing, group I intron RNA is capable of an alternative two-step processing
pathway that results in the formation of full-length intron circular RNA. The circularization …

Group I introns are autonomous genetic elements that can catalyze their own excision from
pre-RNA. Understanding how group I introns move in nuclear ribosomal (r) DNA remains an …

There are currently 47 characterized species in the Naegleria genus of free-living amoebae.
Each amoeba has thousands of extrachromosomal elements that are closed circular …

Summary C hlorella B eijerinck (C hlorellaceae, T rebouxiophyceae) strains from the
collection of the N ational I nstitute for E nvironmental S tudies (NIES) were characterized …

Background Ribosomal DNA of several species of the free-living Naegleria amoeba harbors
an optional group I intron within the nuclear small subunit ribosomal RNA gene. The intron …

Many freshwater protists harbor unicellular green algae within their cells and these host‐
symbiont relationships slowly are becoming better understood. Recently, we reported that …

The ribosomal DNA region of the myxomycete Fuligo septica was investigated and found to
contain 12 group I introns (four in the small subunit and eight in the large subunit ribosomal …

The wide, but scattered distribution of group I introns in nature is a result of two processes;
the vertical inheritance of introns with or without losses, and the occasional transfer of …
