Analysis of expressed sequence tags from Citrus sinensis L. Osbeck infected with Xylella fastidiosa
In order to understand the genetic responses resulting from physiological changes that occur in plants displaying citrus variegated chlorosis (CVC) symptoms, we adopted a strategy of comparing two ...
BigR is a sulfide sensor that regulates a sulfur transferase/dioxygenase required for aerobic respiration of plant bacteria under sulfide stress
To cope with toxic levels of H2S, the plant pathogens Xylella fastidiosa and Agrobacterium tumefaciens employ the bigR operon to oxidize H2S into sulfite. The bigR operon is regulated by the transc...
Characterization and transcriptional analysis of an ECF sigma factor from Xanthomonas campestris pv. campestris
The genomic DNA segment encoding the rpoE gene and its flanking region was cloned from Xanthomonas campestris pv. campestris strain 11 (Xc11). The transcriptional start site of rpoE was located at ...
Chromosome-Based Genetic Complementation System for Xylella fastidiosa
Xylella fastidiosa is a xylem-limited, gram-negative bacterium that causes Pierce's disease of grapevine. Here, we describe the construction of four vectors that facilitate the insertion of genes i...
Comparative analysis of differentially expressed sequence tags of sweet orange and mandarin infected with Xylella fastidiosa
The Citrus ESTs Sequencing Project (CitEST) conducted at Centro APTA Citros Sylvio Moreira/IAC has identified and catalogued ESTs representing a set of citrus genes expressed under relevant stress ...
Drip-irrigated Pecan Seedlings Response to Irrigation Water Salinity
Salinity responses and salinity-related suppression of budbreak of drip-irrigated pecan [Carya ihinoinensis (Wangenh.) K. Koch] seedlings under different irrigation water salinity (ECIRR) levels we...
Drought Stress Predominantly Endures Arabidopsis thaliana to Pseudomonas syringae Infection
Plant responses to a combination of drought and bacterial pathogen infection, an agronomically important and altogether a new stress, are not well-studied. While occurring concurrently, these two s...
Global gene expression analysis of the heat shock response in the phytopathogen Xylella fastidiosa
Xylella fastidiosa is a phytopathogenic bacterium that is responsible for diseases in many economically important crops. Although different strains have been studied, little is known about X. fasti...
Global Transcriptional Analysis Reveals Unique and Shared Responses in Arabidopsis thaliana Exposed to Combined Drought and Pathogen Stress
With frequent fluctuations in global climate, plants are exposed to co-occurring drought and pathogen infection and this combination adversely affects plant survival. In the past, some studies indi...
H-1-NMR Metabolite Fingerprinting Analysis Reveals a Disease Biomarker and a Field Treatment Response in Xylella fastidiosa subsp. pauca-Infected Olive Trees
Xylella fastidiosa subsp. pauca is a xylem-limited bacterial phytopathogen currently found associated on many hectares with the olive quick decline syndrome in the Apulia region (Southern Italy), a...
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...
Identification and in silico analysis of the Citrus HSP70 molecular chaperone gene family
The completion of the genome sequencing of the Arabidopsis thaliana model system provided a powerful molecular tool for comparative analysis of gene families present in the genome of economically r...
