1-Methyltryptophan Treatment Increases Defense-Related Proteins in the Apoplast of Tomato Plants
American Chemical Society (2020-09-29)The activation of induced resistance in plants may enhance the production of defensive proteins to avoid the invasion of pathogens. In this way, the composition of the apoplastic fluid could represent an important layer ... -
Accumulating evidences of callose priming by indole- 3- carboxylic acid in response to Plectospharella cucumerina
Taylor & Francis (2019)Indole-3-carboxylic acid (I3CA) is an indolic compound that induces resistance in Arabidopsis adult plants against the necrotrophic fungus Plectosphaerella cucumerina through primed callose accumulation. In this study, we ... -
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 ... -
Bioassimilable sulphur provides effective control of Oidium neolycopersici in tomato, enhancing the plant immune system
Wiley (2017)BACKGROUND: Developments of alternatives to the use of chemical pesticides to control pests are focused on the induction of natural plant defences. The study of new compounds based on liquid bioassimilable sulphur and its ... -
Chemical priming of immunity without costs to plant growth
Wiley (2018)b-Aminobutyric acid (BABA) induces broad-spectrum disease resistance, but also represses plant growth, which has limited its exploitation in crop protection. BABA perception relies on binding to the aspartyl-tRNA synthetase ... -
Defense Priming: An Adaptive Part of Induced Resistance
Annual Reviews (2017)Priming is an adaptive strategy that improves the defensive capacity of plants. This phenomenon is marked by an enhanced activation of induced defense mechanisms. Stimuli from pathogens, beneficial microbes, or arthropods, ... -
Elucidating the mechanism of action of copper heptagluconate on the plant immune system against Pseudomonas syringae in tomato (Solanum lycopersicum L)
Wiley (2018)BACKGROUND: Phytopathogenic problems caused by the bacterial pathogenPseudomonas syringaein tomato are becomingmore serious due to the emergence of strains resistant to classical pesticides. This has led to research into ... -
Interplay between JA, SA and ABA isgnalling during basal and induced resistance against pseudomonas syringae and Alternaria brasicicola
Wiley-Blackwell (2008)We have examined the role of the callose synthase PMR4 in basal resistance and β‐aminobutyric acid‐induced resistance (BABA‐IR) of Arabidopsis thaliana against the hemi‐biotrophic pathogen Pseudomonas syringae and the ... -
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 ... -
NH4+ protects tomato plants against Pseudomonas syringae by activation of systemic acquired acclimation
Oxford University Press (2015-08)NH4 + nutrition provokes mild toxicity by enhancing H2O2 accumulation, which acts as a signal activating systemic acquired acclimation (SAA). Until now, induced resistance mechanisms in response to an abiotic stimulus and ... -
Optimising grapevine summer stress responses and hormonal balance by applying kaolin in two Portuguese Demarcated Regions
International Viticulture and Enology Society (IVES) (2021-03-01)In Mediterranean-like climate areas, field-grown grapevines are typically exposed to severe environmental conditions during the summer season, which can negatively impact the sustainability of viticulture. Despite the ... -
Preparing to fight back: generation and storage of priming compounds
Frontiers (2014)Immune-stimulated plants are able to respond more rapidly and adequately to various biotic stresses allowing them to efficiently combat an infection. During the priming phase, plant are stimulated in absence of a challenge, ... -
Priming by Hexanoic Acid Induce Activation of Mevalonic and Linolenic Pathways and Promotes the Emission of Plant Volatiles
Frontiers Media (2016-04-12)Hexanoic acid (Hx) is a short natural monocarboxylic acid present in some fruits and plants. Previous studies reported that soil drench application of this acid induces effective resistance in tomato plants against Botrytis ... -
Signal signature of aboveground-induced resistance upon belowground herbivory in maize
Wiley (2009)Plants activate local and systemic defence mechanisms upon exposure to stress. This innate immune response is partially regulated by plant hormones, and involves the accumulation of defensive metabolites. Although local ... -
Tetranychus urticae-triggered responses promote genotype-dependent conspecific repellence or attractiveness in citrus
Wiley (2015)The citrus rootstocks sour orange and Cleopatra mandarin display differential resistance against Tetranychus urticae. Sour orange plants support reduced oviposition, growth rates and damage compared with Cleopatra mandarin ... -
The 'prime-ome': towards a holistic approach to priming
Elsevier (2015-07)Plants can be primed to respond faster and more strongly to stress and multiple pathways, specific for the encountered challenge, are involved in priming. This adaptability of priming makes it difficult to pinpoint an exact ... -
The Induced Resistance Lexicon: Do’s and Don’ts
Elsevier (2021-07-30)To be protected from biological threats, plants have evolved an immune system comprising constitutive and inducible defenses. For example, upon perception of certain stimuli, plants can develop a conditioned state of ...
