storage of freeze dried fungal tissue

[Gregory Forbes]

The oomycete fungus, Phytophthora infestans, is an important plant pathogen
and is routinely studied with several biochemical and molecular markers.  A
convenient way of processing tissue for these analyses is to lyophilize it
and then grind it.  I would appreciate opinions as to whether this
lyophilized tissue would be best stored at room temperature or frozen.  It
seems to me that the apparent advantages of freezing the material could be
counter balanced by the increased risk of rehydration due to condensation in
the storage container (1.5 ml microfuge tubes), if the materials are thawed
and refrozen several times.

Thanks,

Greg
