Based largely on studies of snakes, spiders and other species dangerous to our own, it is thought that most venom genes arise through the mechanism of
gene duplication followed by mutation and repurposing (which scientists refer to as neofunctionalization).
In his research, Dr. Torres examines the properties of plant polyploidy (genome doubling), the concomitant phenomenon of
gene duplication, and the evolution of
genes,
gene families, chromosomes, and genomes
following genome doubling in angiosperms.
