There are colchicine and colcemide resistant strains of yeast around, the
same might be true for other fungi (some lysine mutants in tubulin for
example). To share a horror story - something is growing at the bottom of
John's 1% cycloheximide in the cold room! Looks like them filamentous
fungi only more sinister... Check in the cold room if you don't see me for
few days. Me wife's phone number is above the table.
