In this project, we aim to find a universal plant primer for the Kingdom Plantae, among the three of the most commonly used primers: rbcL, plant ITS, and MatK. We aim to find which one of these primers works best for angiosperms, cryptogams (specifically ferns and mosses), and gymnosperms. We hypothesize that rbcL will be a strong candidate for a universal plant primer since it has the ability to be used for almost all plants and can differentiate plants to at least the genus level.
