Description
Summary:Phosphatidylethanolamine is the main phospholipid of Agaricus bisporus basidiospores obtained under sterile conditions from young basidiomes with closed partial veils. Storing the basidiospores for five months at room temperature resulted in a complete loss of their germinating capacity. Conversely, storing them at a low temperature increased their germination rate by 15-20%. At both temperature levels, the phosphatidyl-choline ratio significantly increased during storage to the level found in mature basidiospores. In addition, a drastic (8-10-fold) decrease in trehalose content occurred after two months of storage at room temperature. The trehalose content decreased only 1.5-fold at low temperatures. The involvement of trehalose and lipids in the retention of spore viability is discussed.
