Implemented by: Michael Melkonian and Barbara SurekA small number of algae samples were extracted using the innuPREP Plant RNA Kit (Analytik Jena, Jena Germany) with either the PL and RL lysis buffer. The method followed the manufacturer’s protocols and so they are not repeated here.This protocol is part of a collection of eighteen protocols used to isolate total RNA from plant tissue.
