Erysiphe necator
TaxID: 52586
Basic Information
Erysiphe necator
Grape Powdery Mildew, Meeldauw (Erysiphe necator), grape powdery mildew
Erysiphe necator, synonym Uncinula necator, is a fungus that causes powdery mildew of grape. It is a common pathogen of Vitis species, including the wine grape, Vitis vinifera. The fungus is believed to have originated in North America. European varieties of Vitis vinifera are more or less susceptible to this fungus. Erysiphe necator infects all green tissue on the grapevine, including leaves and young berries. It can cause crop loss and poor wine quality if untreated. The sexual stage of this pathogen requires free moisture to release ascospores from its cleistothecia in the spring. However, free moisture is not needed for secondary spread via conidia; high atmospheric humidity is sufficient. It produces common odors such as 1-octen-3-one and (Z)-1,5-octadien-3-one. This mildew can be treated with sulfur or fungicides; however resistance to several chemical classes such as Benomyl, the DMIs, and Strobilurins has developed. While synthetic fungicides are often recommended as applications around bloom, it is common to include sulfur in a tank mix to help with resistance management.

PRJNA281110 SRX10085573 SRP057464 fungi RNA sequencing of Erysiphe necator Poly-A RNA was isolated, whole transcriptome amplified, and converted to cDNA with the Qiagen Quantitect Whole Transcriptome Kit. cDNA was fragmented to 200-250 bp using Covaris, ends were repaired, and Illumina adapters T/A ligated, and PCR amplified prior to sequencing. cDNA was sent to the Cornell University Sequencing facility in Ithaca, NY for sequencing library preparation and sequencing on an Illumina sequencer (Illumina, San Diego, CA, USA).
