Cryopreservation of air-dried conidia of Uncinula necator
Australasian Plant Pathology 28 (1), 82-84
Abstract: Conidia of Uncinula necator, the causal agent of grapevine powdery mildew, were viable after storage at –70°C for up to 12 months following air drying without cryoprotectants, as determined by ability to infect surface-sterilised, detached grapevine leaves. The fungus was stored as cyclone-harvested conidia and on segments of infected leaves. Conidia also survived five freeze/thaw cycles. Southern blot analysis revealed that DNA extracted from colonies resulting from cryopreserved and fresh conidia produced the same DNA fingerprints.
