The complete sequence of the 17,553-nucleotide Xenopus laevis mitochondrial genome has been determined. A comparison of this amphibian mitochondrial genomic sequence with those of the mammalian mitochondrial genomes reveals a similar gene order and compact genomic organization. The encoded genes for 22 tRNAs, two ribosomal RNAs, and 13 proteins (COI, COII,(More)
The relative rate of occurrence of nucleotide substitutions versus indel (insertion/deletion) events is investigated by comparing complete DNA sequence data from the noncoding portion of the chloroplast genome that maps between the genes rbcL and atp beta. The sequence data are obtained from nine species that represent three tribes of the grass family.(More)
A cotton Ltp3 gene and its 5' and 3' flanking regions have been cloned with a PCR-based genomic DNA walking method. The amplified 2.6 kb DNA fragment contains sequences corresponding to GH3 cDNA which has been shown to encode a lipid transfer protein (LTP3). The gene has an intron of 80 bp which is located in the region corresponding to the C-terminus of(More)
The phylogenetic relationships of nine genera in four tribes of the family Brassicaceae were estimated from the sequences of the internal transcribed spacer region (ITS) of the 18S-25S nuclear ribosomal DNA. The entire ITS region of 16 accessions belonging to 10 species of seven genera was sequenced. Eight published sequences of Brassicaceae were also used.(More)
Two divergent β-tubulin genes (designated Sβ-1 and Sβ-2) were isolated by screening a soybean genomic library with a Chlamydomonas reinhardtii β-tubulin cDNA probe. Restriction fragment analysis of the clones recovered, and of soybean genomic DNA, indicated that these represent two unique classes of structurally different β-tubulin genes in the soybean(More)
We have completely sequenced two patatin genomic clones Isolated from a genomic library of the potato (Solarium tuberosum L.) cultivar Superior. Comparison of the sequences to the fulllength patatin cDNA, pGMOl (1) permits the assignment of Intron-exon boundaries. Each gene 1s Interrupted by six Introns that vary greatly in length between the two clones.(More)
A full-length cDNA clone, GH3, has been isolated from a cotton fiber cDNA library using a differential screening method. The nucleotide and derived amino acid sequence data show that GH3 encodes a lipid transfer protein (LTP) of 120 amino acids. The presence of a transmembrane signal peptide at the N-terminal of the protein would suggest its possible outer(More)
The full nucleotide sequences of the chloroplast encoded large subunit of ribulose-1,5-bisphosphate carboxylase (rbcL) are available for nine grass species and partial sequence data for one species. Relative rate tests of the "molecular clock" hypothesis suggest that rbcL evolved more rapidly in the lineage leading to Zea than in those leading to the other(More)
The complete sequence of a sunflower (Helianthus annuus) gene, HaG5, encoding a 2 S albumin storage protein was determined. The predicted unprocessed precursor has 295 amino acids, is rich in glutamine residues (24%) and contains a hydrophobic amino-terminus that is similar to the consensus signal peptide. Amino acid sequencing of the mature protein(More)
OBJECTIVE To develop a method to experimentally induce Borrelia burgdorferi infection in young adult dogs. ANIMALS 22 healthy Beagles. PROCEDURE All dogs were verified to be free of borreliosis. Twenty 6-month-old dogs were exposed to Borrelia burgdorferi-infected adult ticks and treated with dexamethasone for 5 consecutive days. Two dogs not exposed to(More)
