Breaking dogmas: the plant vascular pathogen Xanthomonas albilineans is able to invade non-vascular tissues despite its reduced genome
Xanthomonas albilineans, the causal agent of sugarcane leaf scald, is missing the Hrp type III secretion system that is used by many Gram-negative bacteria to colonize their host. Until now, this p...
Data_Sheet_1_Molecular Profiling of Pierces Disease Outlines the Response Circuitry of Vitis vinifera to Xylella fastidiosa Infection
Pierces disease is a major threat to grapevines caused by the bacterium Xylella fastidiosa. Although devoid of a type 3 secretion system commonly employed by bacterial pathogens to deliver effector...
Development of A Nested-MultiLocus Sequence Typing Approach for A Highly Sensitive and Specific Identification of Xylella fastidiosa Subspecies Directly from Plant Samples
Identification of sequence types (ST) of Xylella fastidiosa based on direct MultiLocus Sequence Typing (MLST) of plant DNA samples is partly efficient. In order to improve the sensitivity of X. f...
Hydraulic disruption and passive migration by a bacterial pathogen in oak tree xylem
Xylella fastidiosa (Xf) is a xylem-limited bacterial pathogen that causes leaf scorch symptoms in numerous plant species in urban, agricultural, and natural ecosystems worldwide. The exact mechanis...
Interactive effects of water stress and xylem-limited bacterial infection on the water relations of a host vine
Xylella fastidiosa, a xylem-limited bacterial pathogen that causes bacterial leaf scorch in its hosts, has a diverse and extensive host range among plant species worldwide. Previous work has shown ...
Ionomes of plants infected with vascular pathogens: Xylella fastidiosa as a case study
Recruitment and distribution of metals is fundamental for cell survival, and the mechanisms to maintain the appropriate metal concentrations have been highly conserved. Therefore, an evolutionary a...
Molecular Profiling of Pierce's Disease Outlines the Response Circuitry of Vitis vinifera to Xylella fastidiosa Infection
The role of tyloses in crown hydraulic failure of mature walnut trees afflicted by apoplexy disorder
In the Central Valley of California, mature walnut trees afflicted with apoplexy disorder exhibit rapid and complete crown defoliation within a few weeks of symptom initiation. Symptoms are typical...
Vascular decline in the Oregon Pawpaw Regional Variety Trial
A pawpaw (Asimina triloba) regional variety trial (PRVT) was established at the U.S. Department of Agriculture, Agricultural Research Service, National Clonal Germplasm Repository (NCGR), Corvallis...
Vascular Occlusions in Grapevines with Pierce's Disease Make Disease Symptom Development Worse
Vascular occlusions are common structural modifications made by many plant species in response to pathogen infection. However, the functional role(s) of occlusions in host plant disease resistance/...
Vector-Borne Bacterial Plant Pathogens: Interactions with Hemipteran Insects and Plants
Hemipteran insects are devastating pests of crops due to their wide host range, rapid reproduction, and ability to transmit numerous plant-infecting pathogens as vectors. While the field of plant-v...
Vitis vinifera transcriptome in response to Xylella fastidiosa
Examination of mRNA abundance profiles comparing 5 leaf samples of diseased grapevines (5 trees) to 5 healthy (non-infected) grapevines.
Rationale: Pierce’s disease is a major threat to grapevines c...
