Absence of Cu–Zn superoxide dismutase BCSOD1 reduces Botrytiscinerea virulence in Arabidopsis and tomato plants, revealinginterplay among reactive oxygen species, callose and signallingpathways
Wiley (2017)Plants activate responses against pathogens, including the oxida-tive burst. Necrotrophic pathogens can produce reactive oxygenspecies (ROS) that benefit the colonization process. Previously, wehave demonstrated that tomato ... -
An untargeted global metabolomic analysis reveals the biochemical changes underlying basal resistance and priming in Solanum lycopersicum, and identifies 1-methyltryptophan as a metabolite involved in plant responses to Botrytis cinerea and Pseudomonas syringae
Wiley (2015)n this study, we have used untargeted global metabolomic analysis to determine and compare the chemi-cal nature of the metabolites altered during the infection of tomato plants (cv. Ailsa Craig) with Botry-tis cinerea ... -
Expression of a Fungal Lectin in Arabidopsis Enhances Plant Growth and Resistance Toward Microbial Pathogens and a Plant-Parasitic Nematode
Frontiers Media (2021-04-09)Coprinopsis cinerea lectin 2 (CCL2) is a fucoside-binding lectin from the basidiomycete C. cinerea that is toxic to the bacterivorous nematode Caenorhabditis elegans as well as animal-parasitic and fungivorous nematodes. ... -
Functional analysis of endo-1,4-b-glucanases in response to Botrytis cinerea and Pseudomonas syringae reveals their involvement in plant–pathogen interactions
Wiley (2013)Plant cell wall modification is a critical component in stress responses. Endo-1,4-β-glucanases (EGs) take part in cell wall editing processes, e.g. elongation, ripening and abscission. Here we studied the infection response ... -
Hexanoic acid protects tomato plants against Botrytis cinerea by priming defence responses and reducing oxidative stress
John Wiley & Sons (2014)Treatment with the resistance priming inducer hexanoic acid (Hx) protects tomato plants from Botrytis cinerea by activating defence responses. To investigate the molecular mechanisms underlying hexanoic acid-induced ... -
Hexanoic Acid-Induced Resistance Against Botrytis cinerea in Tomato Plants
The American Phytopathological Society (2009-11)We have demonstrated that root treatment with hexanoic acid protects tomato plants against Botrytis cinerea. Hexanoic acid-induced resistance (Hx-IR) was blocked in the jasmonic acid (JA)-insensitive mutant jai1 (a coi1 ... -
Inactivation of UDP-Glucose Sterol Glucosyltransferases Enhances Arabidopsis Resistance to Botrytis cinerea
Frontiers Media (2019-09-27)Free and glycosylated sterols are both structural components of the plasma membrane that regulate their biophysical properties and consequently different plasma membraneassociated processes such as plant adaptation to ... -
Long-lasting b-aminobutyric acid-induced resistance protects tomato fruit against Botrytis cinerea
Wiley (2018)Minimizing losses to pests and diseases is essential for producing sufficient food to feed the world’s rapidly growingpopulation. The necrotrophic fungus Botrytis cinerea triggers devastating pre- and post-harvest yield ... -
Priming of plant resistance by natural compounds. Hexanoic acid as a model
Frontiers Media (2014-10-01)Some alternative control strategies of currently emerging plant diseases are based on the use of resistance inducers. This review highlights the recent advances made in the characterization of natural compounds that induce ... -
Priming for JA-dependent defenses using hexanoic acid is an effective mechanism to protect Arabidopsis against B. cinerea
Elsevier (2011)Soil drench treatments with hexanoic acid can effectively protect Arabidopsis plants against Botrytis cinerea through a mechanism based on a stronger and faster accumulation of JA-dependent defenses. Plants impaired in ... -
Role and mechanisms of callose priming in mycorrhiza-induced resistance
Oxford University Press (2020-05-09)Mycorrhizal plants display enhanced resistance to several pathogens. However, the molecular mechanisms regulating mycorrhiza-induced resistance (MIR) are still elusive. We aim to study the mechanisms underlying MIR against ... -
Role of dioxygenase α-DOX2 and SA in basal response and in hexanoic acid-induced resistance of tomato (Solanum lycopersicum) plants against Botrytis cinerea
(2015-03)Resistance of tomato (Solanum Lycopersicum) to the fungal pathogen Botrytis cinerea requires complex interplay between hormonal signalling. In this study, we explored the involvement of new oxylipins in the tomato basal ... -
Roots drive oligogalacturonide-induced systemic immunity intomato
(2020-12)Oligogalacturonides (OGs) are fragments of pectin released from the plant cell wall during insect or pathogen attack. They can be perceived by the plant as damage signals, triggering local and systemic defence responses. ... -
Small signals lead to big changes: Deciphering the mechanisms behind Peptide-Induced Resistance in plants
Universitat Jaume I (2022-07-08)To cope with biotic stresses, such as pest and pathogen attacks, plants have evolved a broad variety of adaptative defense strategies. Sometimes plant perception of external stimuli induces an enhanced resistance state ... -
The Histone Marks Signature in Exonic and Intronic Regions Is Relevant in Early Response of Tomato Genes to Botrytis cinerea and in miRNA Regulation
MDPI (2020)Research into the relationship between epigenetic regulation and resistance to biotic stresses provides alternatives for plant protection and crop improvement. To unravel the mechanisms underlying tomato responses to ... -
The nitrogen availability interferes with mycorrhiza-induced resistance against botrytis cinerea in tomato
Frontiers Media (2016)Mycorrhizal plants are generally quite efficient in coping with environmental challenges. It has been shown that the symbiosis with arbuscular mycorrhizal fungi (AMF) can confer resistance against root and foliar pathogens, ...
