In the amoeboid protozoon Acanthamoeba castellanii 13 of the 16 mtDNA-encoded tRNA sequences have mis-matches at one or more of the first three positions in the acceptor stem. A previous study had indicated that these mis-matches are corrected by a f

U3 small nucleolar RNA (snoRNA) has been isolated from Euglena gracilis, an early diverging protist, and its primary sequence determined. Although this 180-nucleotide-long RNA is considerably smaller than its homolog in vertebrate animals, it contain

A restriction-fragment-length polymorphism (RFLP) in mitochondrial DNA (mtDNA) was detected between varieties of fall rye (Secale cereale L.) by Southern hybridization with rrn18, the gene encoding the mitochondrial 18S ribosomal RNA. Restriction map

Phylum Euglenozoa comprises three groups of eukaryotic microbes (kinetoplastids, diplonemids, and euglenids), the mitochondrial (mt) genomes of which exhibit radically different modes of organization and expression. Gene fragmentation is a striking f

In the mtDNA of Chlamydomonas reinhardtii, a unicellular green alga, we have identified a set of short repeated sequences up to 65 nucleotides long, each of which contains the palindromic consensus motif CTCGG(N4-14)CCGAG. Most of these repeated elem

The mitochondrial 18S and 5S ribosomal RNA (rRNA) genes of rye, plus a total of about 90 kilobase pairs of flanking DNA, have been cloned and maps of restriction enzyme cleavage sites have been constructed. Like their homologs from hexaploid wheat, t

The mitochondrial genomes of wheat and rye each contain a three-member family of recombining repeat sequences (the "18S/5S repeat") that encode genes for 18S and 5S rRNAs (rrn18 and rrn5) and tRNA(fMet) (trnfM). Here we present, for wheat and rye, th

To identify transcription initiation sites in wheat mitochondria, the nascent 5'-ends of transcripts were specifically labeled by incubation of wheat mitochondrial RNA with [alpha-32P]GTP in the presence of the enzyme guanylyltransferase. After separ

We present the cloning and sequence analysis of the nuclear-encoded Crithidia fasciculata small subunit (SSU) rRNA gene, the longest (2,206 bp) such gene yet characterized by direct sequence analysis. Much of the sequence can be folded to fit a phylo

We have isolated Phe and Tyr tRNAs from Tetrahymena pyriformis mitochondria and have determined that these are "native" species, encoded by the mtDNA. A single gene for the tRNA(Phe) has been positioned 12-14 kbp from the left end of the linear Tetra
