Phospholipid acylhydrolases trigger membrane degradation during fungal sporogenesis

► Phospholipid acylhydrolase is present in fruiting bodies of several basidiomycetes. ► In Armillaria ostoyae, phospholipase A1 activity is specific for sporogenic tissue. ► The A. ostoyae, phospholipase A1 is expressed in the phase of spore release. ► Phospholipase A1 generates fatty acids for spore storage lipid from phospholipids.
