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 ...
Antennal olfactory responses of adult meadow spittlebug, Philaenus spumarius, to volatile organic compounds (VOCs)
The meadow spittlebug, Philaenus spumarius L. (Hemiptera, Aphrophoridae) is a commonly found vector of Xylella fastidiosa Wells et al. (1987) strain subspecies pauca associated with the "Olive Quic...
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 ESTs involved in grape responses to Xylella fastidiosa infection
The gram-negative bacterium Xylella fastidiosa (Xf) is the causal agent of Pierce's disease (PD) in grape as well as diseases of many fruit and ornamental plants. The current molecular breeding eff...
Differential Responses of Tobacco to the Citrus Variegated Chlorosis and Coffee Stem Atrophy Strains of Xylella fastidiosa
Xylella fastidiosa comprises a diverse group of xylem-limited, insect-transmitted bacterial pathogens. In Brazil, the citrus variegated chlorosis (CVC) and coffee stem atrophy (CSA) diseases are ...
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 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...
Lipopolysaccharide O-antigen delays plant innate immune recognition of Xylella fastidiosa
Lipopolysaccharides (LPS) are among the known pathogen-associated molecular patterns (PAMPs). LPSs are potent elicitors of PAMP-triggered immunity (PTI), and bacteria have evolved intricate mechani...
Molecular Effects of Xylella fastidiosa and Drought Combined Stress in Olive Trees
Due to global climate change, complex combinations of stresses are expected to occur, among which the interaction between pathogens and drought stress may have a significant effect on growth and yi...
Ohr plays a central role in bacterial responses against fatty acid hydroperoxides and peroxynitrite
Organic hydroperoxide resistance (Ohr) enzymes are unique Cysbased, lipoyl-dependent peroxidases. Here, we investigated the involvement of Ohr in bacterial responses toward distinct hydroper-oxides...
Pierce's disease symptoms: Comparison with symptoms of water deficit and the impact of water deficits
The pathology of diseases such as Pierce's disease (PD) of grapevine (Vitis vinifera L.) that are caused by the xylem-limited bacterium Xylella fastidiosa (Xf) is widely attributed to vessel occlus...
Transcriptome changes in Arabidopsis thaliana infected with Pseudomonas syringae during drought recovery
Field-grown plants experience cycles of drought stress and recovery due to variation in soil moisture status. Physiological, biochemical and transcriptome responses instigated by recovery are expec...
