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 ... -
Advances in induced resistance by natural compounds: towards new options for woody crop protection
São Paulo - Escola Superior de Agricultura "Luiz de Queiroz" (2017)The activation of defensive responses of plants is a promising tool for controlling pests in conventional agriculture. Over the last few years, several compounds have been studied to protect crops from pests, without ... -
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 ... -
Bacterial Endophytes: The Hidden Actor in Plant Immune Responses against Biotic Stress
MDPI (2021-05-19)Bacterial endophytes constitute an essential part of the plant microbiome and are described to promote plant health by different mechanisms. The close interaction with the host leads to important changes in the physiology ... -
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 ... -
Combining Hexanoic Acid Plant Priming with Bacillus thuringiensis Insecticidal Activity against Colorado Potato Beetle
MDPI (2013)Interaction between insect herbivores and host plants can be modulated by endogenous and exogenous compounds present in the source of food and might be successfully exploited in Colorado potato beetle (CPB) pest ... -
Deciphering of benzothiadiazole (BTH)-induced response of tomato (Solanum lycopersicum L.) and its effect on early response to virus infection through the multi-omics approach
Springer Nature (2022-08-22)Background and aims: One of the preventive methods used to limit the losses caused by viruses is the application of synthetic immunity inducers, such as benzo(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH). ... -
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, ... -
Editorial: Induced resistance and priming against pests and pathogens
Frontiers Media (2022)Due to the rapidly changing climate and increasingly restrictive regulations on the use of pesticides, there is an urgent need to discover and develop new and more sustainable strategies of crop protection that meet the ... -
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 ... -
Mycorrhiza l tomato plants fine tunes the growth‐defencebalance upon N depleted root environments
Wiley (2018)In low nutritive environments, the uptake of N by arbuscular mycorrhizal (AM) fungi may confercompetitive advantages for the host. The present study aims to understand how mycorrhizaltomato plants perceive and then prepare ... -
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, ... -
Resistance Induction in Olive Tree (Olea europaea) Against Verticillium Wilt by Two Beneficial Microorganisms and a Copper Phosphite Fertilizer
(2022)Enhancement of the natural defenses of a plant by beneficial microorganisms, i.e., endophytic bacteria and fungi or fertilizers such as copper phosphonates, could result in a potential alternative strategy against verticillium ... -
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 ... -
Root metabolic plasticity underlies functional diversity inmycorrhiza-enhanced stress tolerance in tomato
Wiley (2018)Arbuscular mycorrhizal (AM) symbioses can improve plant tolerance to multiple stresses.We compared three AM fungi (AMF) from different genera, one of them isolated from a dryand saline environment, in terms of their ability ... -
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 ... -
Small Signals Lead to Big Changes: The Potential of Peptide-Induced Resistance in Plants
MDPI (2023-02-16)The plant immunity system is being revisited more and more and new elements and roles are attributed to participating in the response to biotic stress. The new terminology is also applied in an attempt to identify different ... -
