The protocol presented herein is based on a modified version of the
SDS/PCI method of Mortaji et al. (2008) for RNA extraction from wheat
seeds. For comparative purposes, an established protocol for RNA extraction
from strawberry leaves and petioles using LiCl and sodium dodecyl
sulfate (SDS) in the extraction buffer (Mazzara and James, 2000),
as well as a commercially available, ready-to-use reagent (TRIzol® Reagent,
Invitrogen) commonly used for nucleic acid extraction have
also been tested. The proposed protocol was subsequently employed
for successful RNA extraction from other fruits such as olive and
kiwifruit.
