ITS sequencing of Vitis vinifera L. cvs. Chardonnay and Pinot noir phyllosphere and grape must.

The effects of development, location, and cultivar on fungal composition and structure were assessed through high-throughput amplicon sequencing to profile the fungal communities of the phyllosphere and within grape must. The fungal communities present in the phyllosphere and within grape must from Chardonnay and Pinot noir vineyards in the Hemel en Aarde Valley and Elgin wine region were investigated. This study contributes to the understanding of fungal and diversity in the phyllosphere of Chardonnay and Pinot noir within the novel South African context.
