Repeated polyploidization of Gossypium genomes and the evolution of spinnable cotton fibres

Andrew H. Paterson, +77 more
- 20 Dec 2012 - 
TL;DR: It is shown that an abrupt five- to sixfold ploidy increase approximately 60 million years (Myr) ago, and allopolyploidy reuniting divergent Gossypium genomes approximately 1–2 Myr ago, conferred about 30–36-fold duplication of ancestral angiosperm genes in elite cottons, genetic complexity equalled only by Brassica among sequenced angiosperms.
Journal ArticleDOI

Two common mitochondrial DNA polymorphisms are highly associated with migraine headache and cyclic vomiting syndrome.

TL;DR: The data suggest that these polymorphisms constitute a substantial proportion of the genetic factor in migraine pathogenesis, and strengthen the hypothesis that there is a component of mitochondrial dysfunction in migraine.
Journal ArticleDOI

Involvement of the amino terminus of the b2 receptor in agonist-induced receptor dimerization

TL;DR: It is suggested that the amino terminus of the B2 receptor is necessary for triggering agonist-induced B 2 receptor dimerization, and receptor dimers are involved in receptor-mediated signal attenuation.
Journal ArticleDOI

Molecular characterization of phenol-degrading bacteria isolated from different egyptian ecosystems

TL;DR: Molecular heterogeneity among the phenol-degrading isolates was further investigated by using rep-PCR chromosomal fingerprinting and correlated with plasmid and antibiotic profile analysis, which strongly confirmed that the bacterial isolates from different environmental sites produced different fingerprinting patterns.
Journal ArticleDOI

Mitochondrial DNA and gastrointestinal motor and sensory functions in health and functional gastrointestinal disorders

TL;DR: Variation in mtDNA may be associated with satiation, gastric emptying, and possibly pain; further studies of mtDNA in appetite regulation and larger numbers of patients with FGIDs are warranted.
