Columnar apple trees (Malus x domestica) provide several economic advantages due to their specific growth habit. The columnar phenotype is the result of the dominant allele of the gene Co and is characterized by thick stems with short internodes and reduced lateral branching. Co is located on chromosome 10 and often appears in a heterozygous state (Co/co). The molecular explanation of columnar growth...
The terminal enzyme of the mitochondrial respiratory chain, cytochrome c oxidase (COX), contains three mitochondrial and ten nuclear encoded subunits in mammals. Three of the nuclear subunits (VIa, VIIa, and VIII) have muscle and non-muscle-specific isoforms, subunit IV contains a lung-specific isoform, and subunit VIb contains a testes-specific isoform. For subunit VIII, the smallest nuclear encoded...
We examined inferred amino acid replacements for 16 genes that encode the proteins of the cytochrome c oxidase (COX) holoenzyme in eight vertebrate species. Phylogeny-based analysis revealed that the human lineage (primates) has had an unusually large, statistically significant, number of amino acid replacements in the mature protein coding region of these genes. This finding is similar to earlier...
Human chromosomal region 11p15 is known to be associated with several diseases including predispositions to develop various tumor types. In search of candidate genes, a novel human kinase gene is described, STK33, which codes for a serine/threonine protein kinase. The gene was discovered by comparative genome analysis of human chromosome 11p15.3 and its orthologous region on distal mouse chromosome...
The intron positions found in globin genes of plants, protozoa and invertebrates have been interpreted as evidence for a three-intron-four-exon structure of the ancestral globin gene. In particular, the so-called central introns, which are not found in vertebrate globin genes but are present in a variety of invertebrate and plant species, have been used as an argument for an ancestral gene structure...
