Abstract

The grapevine represents a natural reservoir of resident microbial resources embedded in a complex microecosystem. The aim of this study was to find out which germs are present in the bleeding sap. The bleeding juice was obtained using a clean with alcohol sterilized PET bottle. After enrichment, DNA extraction followed by analysis of an Illumina MiSeq v3 with target region V1V3 was examined. The sequences obtained were aligned with the NCBI database. The most dominant genera in the grapevines were Pseudomonas and Massilia followed by the genera Zoogloea, Bacillus, Idonella, Sphingomonas and Paenibacillus. Sporadically, other bacterial genera appeared in the vines. In addition, the yeast-like microorganism Aureobasidium pullulans was determined in two vines and the described inhibitory interaction between Pseudomonas and Aureobasidium was confirmed as described in the literature. In general, all microorganisms determined in the bleeding sap have a plant-strengthening influence and provide a basis for colonization into tissue-specific plant parts.
