Simplifying SNP discovery in the cotton genome

The term "single-nucleotide polymorphism" (SNP) refers to a single base change in DNA sequence between two individuals. SNPs are the most common type of genetic variation in plant and animal genomes and are, thus, an important ...

Cotton breeding researchers take giant leap

Narrow germplasm base and limited technology have made it difficult for cotton researchers to identify specific DNA markers needed to locate genes that confer desirable traits. But that's no longer the case.

Conserving corals by understanding their genes

In reef-building corals variations within genes involved in immunity and response to stress correlate to water temperature and clarity, finds a study published in BioMed Central's open access journal BMC Genetics. This information ...

Predicting the effects of changes on living systems

Can scientists predict what happens when they introduce a change into a living system—for example, if they change the structure of a gene or administer a drug? Just as changing one letter can completely change the meaning ...

Insights into primate diversity: Lessons from the rhesus macaque

New research published in BMC Genetics shows that the rhesus macaque has three times as much genetic variation than humans. However despite much of this extra variation being within genes, it does not affect protein function. ...

Largest rice genetics study finds vast differences in rice

The largest publicly available genomewide association mapping study in rice to date has found that although the five subpopulations of Asian rice -- indica, aus, temperate japonica, aromatic and tropical japonica -- all belong ...
