Lactate dehydrogenase-B cDNA from the teleost Fundulus heteroclitus: evolutionary implications.

abstract：:Gene duplication is a major driving force in genome evolution. Here, we explore the nature and origin of the POT1 gene duplication in Arabidopsis thaliana. Protection of Telomeres (POT1) is a conserved multifunctional protein that modulates telomerase activity and its engagement with telomeres. Arabidopsis thaliana en...
