By "digestion", do you mean restriction digestion. I was under the
impression that plant nuclear genomic DNA tends to be resistant to the
action of some restriction enzymes to to its (highly?) methylated state.
BTW, the DNA should be viscous if it's a good prep. The addition of DNase
should get rid of the viscosity in a matter of minutes, if in fact it is
