Subfunctionalization neofunctionalization

WebWe conclude that expression divergence specifically indicative of subfunctionalization and/or neofunctionalization contributes to the maintenance of most if not all duplicated regulatory genes in Arabidopsis and hypothesize that this results in increasing expression diversity or specificity of regulatory genes after each round of duplication. Web17 Feb 2012 · Either the neofunctionalized developmental gene copies alone, or a combination of sub- and neofunctionalized copies are hypothesized to provide the raw genetic material necessary for the production of novel morphological structures.

WebFunctional divergence is the process by which genes, after gene duplication, shift in function from an ancestral function.Functional divergence can result in either subfunctionalization, where a paralog specializes one of several ancestral functions, or neofunctionalization, where a totally new functional capability evolves.It is thought that this process of gene … Web3 Nov 2024 · Studies point out that duplicated genes will result in neofunctionalization and subfunctionalization [40,41].
