Expression of PrCel1 and PrCel2 genes in different
radiata pine tissues. Total RNA (20 μg per lane) isolated from 5, 50,
and 100 mg of SCB and PCB, needles, stems, and roots was hybridized
with 32P-labeled PrCel1 and PrCel2 probes. The loading of
equivalent amounts of RNA was confirmed by hybridization with a
32P-labeled rRNA clone. M, Markers (in kb).
