Gene Duplication, Shifting Selection, and Dosage Balance of Silicon Transporter Proteins in Marine and Freshwater Diatoms
Numerous factors shape the evolution of protein-coding genes, including shifts in the strength or type of selection followinggene duplications or changes in the environment. Diatoms and other silicifying organisms use a family of silicon transporters(SITs) to import dissolved silicon from the environment. Freshwaters contain higher silicon levels than oceans, and marinediatoms have more efficient
