Speciation genes restrict gene flow between the incipient species and related taxa. Three
decades ago, we mapped a mammalian speciation gene, hybrid sterility 1 (Hst1), in the …

Only a small proportion of cancers result from familial cancer syndromes with Mendelian
inheritance. Nonfamilial,'sporadic'cancers, which represent most cancer cases, also have a …

Seven DNA extraction protocols were used to obtain DNA from herbarium specimens ofJuncus
andLuzula (Juncaceae) of various ages. DNA of historical samples is difficult to extract, …

Soils of coniferous forest ecosystems are important for the global carbon cycle, and the
identification of active microbial decomposers is essential for understanding organic matter …

Animal eyes are morphologically diverse. Their assembly, however, always relies on the
same basic principle, ie, photoreceptors located in the vicinity of dark shielding pigment. …

We report a cluster of genes encoding two monooxygenases (SadA and SadB) and one FMN
reductase (SadC) that enable Microbacterium sp. strain BR1 and other Actinomycetes to …

Bovine herpesvirus 1 (BHV-1) contains three major immediate-early (IE) genes involved in
regulation of the productive cycle of replication. Two spliced IE RNAs, IER4.2 (4.2 kb) and …

Cystathionine β-synthase (CBS) catalyzes the irreversible, serine-dependent conversion of
homocysteine to cystathionine via a transsulfuration pathway. CBS deficiency not only is the …

The presence of mitochondria and related organelles in every studied eukaryote supports
the view that mitochondria are essential cellular components. Here, we report the genome …

Bacteria were identified associated with biodegradation of aromatic pollutants biphenyl,
benzoate, and naphthalene in a long-term polychlorinated biphenyl- and polyaromatic …
