Chloroplast-like transfer RNA genes expressed in wheat mitochondria.

In the course of a systematic survey of wheat mitochondrial tRNA genes, we have sequenced chloroplast-like serine (trnS-GGA), phenylalanine (trnF-GAA) and cysteine (trnC-GCA) tRNA genes and their flanking regions. These genes are remnants of 'promiscuous' chloroplast DNA that has been incorporated into wheat mtDNA in the course of its evolution. Each gene differs by one or a few nucleotides fro...

Chloroplast DNA codes for transfer RNA . Jan

Transfer RNA's were isolated from Euglena gracilis. Chloroplast cistrons for tRNA were quantitated by hybridizing tRNA to ct DNA. Species of tRNA hybridizing to ct DNA were partially purified by hybridization-chromatography. The tRNA's hybridizing to ct DNA and nuclear DNA appear to be different. Total cellular tRNA was hybridized to ct DNA to an equivalent of approximately 25 cistrons. The tot...

Transfer RNA genes in pieces.

The short genes encoding transfer RNA (tRNA) molecules are highly conserved in both sequence and structure, reflecting the central role of tRNA in protein biosynthesis. The frequent occurrence of fragmented intron-containing tRNAs that require processing to form contiguous molecules is therefore surprising. Recent discoveries of permuted and split tRNA genes have added to the apparent creativit...

Embedded transfer RNA Genes

In euryarchaeal methanogen M.kandleri and in Nanoarchaea N. equitans some of the missing tRNA genes are embedded in others. We argue from bioinformatic evidence that position specific intron splicing is the key behind colocation of these tRNA genes.

Maize chloroplast RNA polymerase: the 180-, 120-, and 38-kilodalton polypeptides are encoded in chloroplast genes.

Prominent polypeptides with apparent molecular masses of 180, 120, 85, and 38 kDa are found in an extensively purified preparation of maize chloroplast DNA-dependent RNA polymerase that retains the capacity to initiate transcription of the cloned chloroplast gene rbcL correctly and the requirement for a supercoiled DNA template for specific and active transcription. Amino-terminal amino acid se...
