Gene trees and species trees can be incongruent for many reasons. (A) Genes can have unequal rates of evolution. (B) Gene loss and gene duplication are common. (C) Gene flow can occur between ...

Gene tree and species tree reconciliation is a crucial area of study in evolutionary biology that seeks to understand the relationships between gene evolution and species evolution. This process ...

2006). In order to enhance blight-tolerance in the American chestnut tree, we are studying several gene products, regulatory regions of genes to control expression (promoters), and the possibility of ...

In a new study involving whole-genome data, researchers present “CASTER,” a tool that uses arrangements in DNA sequences known as site patterns to infer “species trees,” which are diagrams that depict ...

A team of scientists have identified a gene in poplar trees that enhances photosynthesis and can boost tree height. The study, "An orphan gene BOOSTER enhances photosynthetic efficiency and plant ...

Researchers pinpointed the gene that deprives Japanese cedar trees of their ability to produce pollen, carving out the future where no one may suffer the agony brought about by hay fever ...
