Testing protocols to optimize DNA extraction from tough leaf tissue: A case study in Encephalartos
Applications in Plant Sciences, 2023 Premise Plants with stiff, leathery leaves pose a challenge for standard DNA extraction protocols. These tissues are recalcitrant to mechanical disruption via TissueLyser (or analogous devices) and are often high in secondary metabolites.
