Searching DNA isolation methods from plant tissue culture

I'm working with transformed Phaseolus vulgaris callus cultures
and I want to start with molecular DNA analysis (southern/dot
blot).I can't obtain enough DNA (not more than 1.5 ug/5 g fresh
weight) from a limited amount of callus material with conventional
DNA isolation methods (Dellaporta>Maize mini prep and
Rogers/Bendich >CTAB method).
I`m searching for a genomic DNA isolation method from calli.
Any help would be appreciated.
