Tobacco is one of a handful of plant "model organisms", basically meaning that we have a lot of studies already done and genetic / metabolic information about it available.
Scientists like using these when doing basic research of, e.g. gene function, because that wealth of prior information available reduces the amount of "unknown unknowns" to account for.
