The Complete Mitochondrial Genome of Gossypium hirsutum and Evolutionary Analysis of Higher Plant Mitochondrial Genomes
BACKGROUND Mitochondria are the main manufacturers of cellular ATP in eukaryotes. The plant mitochondrial genome contains large number of foreign DNA and repeated sequences undergone frequently intramolecular recombination. Upland Cotton (Gossypium hirsutum L.) is one of the main natural fiber crops and also an important oil-producing plant in the world. Sequencing of the cotton mitochondrial (...
متن کاملAppraisal of the entire mitochondrial genome for DNA barcoding in birds
DNA barcoding based on a standardized region of 648 base pairs of mitochondrial DNAsequences from Cytochrome C Oxidase 1 (COX1) is proposed for animal species identification.Recent studies suggested that DNA barcoding has been effective for identifying 94% of birdspecies. The proposed threshold of 10 times the average intraspecific variation could be used forthe identification and delimitation ...
متن کاملThe plant mitochondrial genome: dynamics and maintenance.
Plant mitochondria have a complex and peculiar genetic system. They have the largest genomes, as compared to organelles from other eukaryotic organisms. These can expand tremendously in some species, reaching the megabase range. Nevertheless, whichever the size, the gene content remains modest and restricted to a few polypeptides required for the biogenesis of the oxidative phosphorylation chai...
متن کاملPreliminary analysis of the mitochondrial genome evolutionary pattern in primates.
Since the birth of molecular evolutionary analysis, primates have been a central focus of study and mitochondrial DNA is well suited to these endeavors because of its unique features. Surprisingly, to date no comprehensive evaluation of the nucleotide substitution patterns has been conducted on the mitochondrial genome of primates. Here, we analyzed the evolutionary patterns and evaluated selec...
متن کاملThe Mitochondrial Genome of an Aquatic Plant, Spirodela polyrhiza
BACKGROUND Spirodela polyrhiza is a species of the order Alismatales, which represent the basal lineage of monocots with more ancestral features than the Poales. Its complete sequence of the mitochondrial (mt) genome could provide clues for the understanding of the evolution of mt genomes in plant. METHODS Spirodela polyrhiza mt genome was sequenced from total genomic DNA without physical sep...
