A MotN Mutant of Ralstonia solanacearum Is Hypermotile and Has Reduced Virulence
Ralstonia solanacearum is a soil-borne plant pathogen that causes bacterial wilt disease on many plant species. We previously showed that swimming motility contributes to virulence of this bacteriu...
Cassava endophytic microorganisms of commercial plantings and ethnovarieties in three Brazilian states
The aim of this work was to perform a survey of the diversity of endophytic microorganisms in cassava (Manihot esculenta Crantz) collected from commercial plantings, in the State of Sao Paulo, and ...
Causes and consequences of plant-associated biofilms
The rhizosphere is the critical interface between plant roots and soil where beneficial and harmful interactions between plants and microorganisms occur. Although microorganisms have historically b...
Differential Susceptibility of Prunus Germplasm (Subgenus Amygdalus) to a California Isolate of Xylella fastidiosa
Seedling peach (Prunus persica Batsch) and clonal peach-almond hybrids are popular rootstock choices for commercial almond growers in California. In this study, clonal replicates of peach and almon...
DISTRIBUTION OF XYLELLA-FASTIDIOSA WITHIN ROOTS OF PEACH
The distribution of Xylella fastidiosa, the bacterium that causes phony peach disease, was studied in roots of 10 Flordaking peach scions grafted on Nemaguard rootstock. X. fastidiosa was detected ...
Diversity of endophytic bacteria in Brazilian sugarcane
Endophytic bacteria live inside plant tissues without causing disease. Studies of endophytes in sugarcane have focused on the isolation of diazotrophic bacteria. We examined the diversity of endoph...
Diversity of endophytic bacterial populations and their interaction with Xylella fastidiosa in citrus plants
Citrus variegated chlorosis (CVC) is caused by Xylella fastidiosa, a phytopathogenic bacterium that can infect all Citrus sinensis cultivars. The endophytic bacterial communities of healthy, resist...
Endosphere microbiome comparison between symptomatic and asymptomatic roots of Brassica napus infected with Plasmodiophora brassicae
Clubroot caused by Plasmodiophora brassicae, is a severe disease of cruciferous crops that causes large hypertrophic galls in the roots. The plant microbiome is important for growth promotion and d...
GRAPEVINE NECROTIC UNION, A NEWLY RECOGNIZED DISEASE OF UNKNOWN ETIOLOGY IN GRAPEVINES GRAFTED ON 110 RICHTER ROOTSTOCK IN CALIFORNIA
In Northern California, surveys of several vineyards planted to Vitis vinifera cv. Pinot noir (PN) clones 02A, 667, 777, and UCD 04 grafted onto the rootstock V berlandieri x V rupestris 110 Richte...
Grapevine rootstock effects on scion sap phenolic levels, resistance to Xylella fastidiosa infection, and progression of Pierce's disease
The xylem-limited bacterium Xylella fastidiosa (Xf) causes Pierce's disease (PD), an important disease of grapevine, Vitis vinifera L. Grapevine rootstocks were developed to provide increased resis...
Identification and characterization of endophytic bacteria isolated from in vitro cultures of peach and pear rootstocks
Endophytes are microorganisms which live symbiotically with almost all varieties of plant and in turn helping the plant in a number of ways. Instead of satisfactory surface sterilization approaches...
Passive Pathogen Movement via Open Xylem Conduits in Grapevine Graft Unions
In grapevines, scion-rootstock grafting is a common practice to impart pathogen resistance and to manipulate aspects of grapevine physiology, including vigor, yield, and fruit composition. Successf...
