Animal mtDNAs are typically small (≈16 kbp), circular-mapping molecules that encode 37 or fewer tightly packed genes. Here we investigate whether similarly compact mitochondrial genomes are also present in the closest unicellular relatives of anima

In the flagellated protozoon Euglena gracilis , characterized nuclear genes harbor atypical introns that usually are flanked by short repeats, adopt complex secondary structures in pre-mRNA, and do not obey the GT-AG rule of conventional cis-spliced

To date, most studies of group I intron mobility have dealt with intraorganismal transfer occurring between intron+ and intron− alleles of particular genes during genetic crosses. Little is known about the frequency and extent of horizontal transfe

In 1989, three groups simultaneously and independently discovered RNA editing in the mitochondria of angiosperms (flowering plants; refs. 1-3). Two years later, H. Kossel and colleagues reported the same type of editing in angiosperm chloroplasts (4)

Higher plants occupy very different positions in the mitochondrial and nuclear lineages of global phylogenetic trees based on conserved regions of small subunit (SSU) and large subunit (LSU) rRNA sequences. In the nuclear subtree, plants branch off l
