The hypothesis, however, needs to be tested on a broad range of organisms.
A variety of methods to create specific constructs for protein expression, in a broad range of organisms, are available nowadays.
β-Glucosidase is distributed throughout a broad range of organisms, including microbes, plants, and animals (Chang et al. 2008; Knight and Dick 2004).
Thereby, we have designed a primer pair capable of amplifying a broad range of organisms: Cyanobacteria, Chlorophyta, Chlorarachniophyta, Cryptophyta, Euglenida, Glaucophyta, Rhodophyta, Stramenopiles and Streptophyta including plants.
To give an example, a highly conserved sequence element called the "homeobox", which was first described in Drosophila, is today believed to play a similar role in development in an extremely broad range of organisms (Gehring 1998).
Application of new genomic methods is likely to lead to the discovery of many additional supergenes in a broad range of organisms and reveal similar genetic architectures for convergently evolved phenotypes.
Selenium is an essential part of certain enzymes and proteins for a broad range of organisms, from the sunlight-harvesting phytoplankton at the base of the food chain to the vertebrates that ultimately depend on them (such as the marine reptile Lariosaurus, shown, whose group died out with many others about 201 million years ago).
WDR exists in a broad range of organisms from yeasts to mammals as well as plants.
Enrichment of rare codon clusters in such a broad range of organisms suggests a general evolutionary selection pressure for clustering, despite the established negative effects on local translation rate.
The significant clustering of rare codons reported here suggests there is strong selective pressure to maintain rare codon clusters in a wide variety of genes, across a broad range of organisms, and runs counter to the assumption that synonymous codon substitutions are essentially genomic background noise [20].
Over a broad range of organisms, retrotransposon copy number appears to be correlated with genome size.
