Bleeding sap and old wood are the two main sources of contamination of merging organs of vine plants by Xylophilus ampelinus, the causal agent of bacterial necrosis
Article Abstract:
The spatial distribution of vine plants contaminated by Xylophilus ampelinus, the agent responsible for bacterial necrosis, is analyzed within two vineyards in the Cognac area and the emission of X. ampelinus in contaminated bleeding sap is observed during vine sprouting. The symptoms are rare and are observed on different plants each year, even though all plants are entirely contaminated in both vineyards.

Colonization of Vitis vinifera by a green fluorescence protein-labeled, gfp_marked strain of Xylophilus ampelinus, the casual agent of bacterial necrosis of grapewine
Article Abstract:
The colonization by Xylophilus ampelinus of Vitis vinifera progresses to the crown through xylem vessels but fail to colonize emerging plantlets, suggesting that xylem vessels play a role in the multiplication and conservation of the bacteria. Colonization of the sprayed bacteria onto the plants occurs both via emerging organs and down to the crown simulating epiphytic colonization.

Endophytic colonization of Vitis vinifera L. by plant growth promoting bacterium Burkholderia sp. strain PsJN
Article Abstract:
A study of patterns of colonization of Vitis vinifera L. cv. Chardonnay plantlets by a plant growth-promoting bacterium, Burkholderia sp. strain PsJN is presented under gnotobiotic conditions. It is concluded that Burkholderia sp. strain PsJN induces a local host defense reaction and systematically spreads to aerial parts through the transpiration stream.
