Abstract
A procedure is presented for the detection of mRNA in whole-mount preparations of youngArabidopsis seedlings using digoxigenin (DIG)-labeled RNA probes. It includes tissue preservation with formaldehyde, permeabilization with polyoxyethy lenesorbitan (Tween 20), DMSO, and heptane. Hybridization signal is detected using colloidal gold or alkaline-phosphatase-conjugated anti-DIG antibodies.
