Analysis of soil properties and bacterial genera influencing the soil-borne culturable bacterial community in a california grapevine vineyard. American Phytopathological Society Abstracts.Interpretive Summary:
                                Technical Abstract: Bacteria have significant roles in the soil ecosystem of agricultural production systems including nutrient cycling, disease suppression, hormone production, and nutrient acquisition.  Until recently, the composition and diversity of bacteria in the soil community of grapevine vineyards had been largely uncharacterized.  Information regarding the factors that affect the bacteria composition of grapevine soils has not been reported.  Soil chemical and physical properties were analyzed from different soil horizons in pits dug at different typographical locations in a commercial vineyard in the Carneros Region of the Napa Valley, California.  From these same soils, culturable aerobic bacteria from rhizosphere and bulk soils were randomly selected and identified to genus.  Here we report on physical and chemical properties of the soil found to influence the presence and absence of specific culturable bacterial genera, and the population levels of those culturable members.  Using principle component analysis, the high populations of some bacterial genera were found to correlate with low populations of other genera.  The soil properties found to affect the presence and abundance of the bacterial genera in the pits will be discussed, as well as correlations found between population and composition of some culturable members.
