... Early pollen-stigma interactions are mediated by the exine layer of the cell wall and the pollen coat. In Brassica oleracea and Arabidopsis thaliana this pollen coat is enriched in low molecular weight proteins (6-10kDa) that are highly basic and appear to be highly polymorphic except for a conserve ...

It is a rhadinovirus, and is remarkable since it has stolen numerous genes from host cells including genes that encode for complementbinding protein, IL-6, BCL-2, cyclin-D, a G prot ...

Molecular evolution

Molecular evolution is a change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, evolution of development, and ways that evolutionary forces influence genomic and phenotypic changes.
