Extracellular DNA induces resistance against Frankliniella occidentalis through callose accumulation
Rassizadeh, Leila; Cañadas, Estela; Cervero, Raquel; Flors, Victor; Gamir, Jordi Springer (2024-01-10)The plant immune system has evolved to sense and respond to potential threats. When an insect attacks a plant, endogenous molecules called damage-associated molecular patterns (DAMPs) are released into the apoplast, ... -
Identification of new antifungal metabolites produced by the yeast Metschnikowia pulcherrima involved in the biocontrol of postharvest plant pathogenic fungi
Fernandez San Millan, Alicia; Gamir, Jordi; Farran, Inmaculada; Larraya, Luis M.; Veramendi, Jon Elsevier ScienceDirect (2022-06-11)Several strains of the yeast Metschnikowia pulcherrima exhibit strong antagonistic activity against postharvest pathogens and may have broad biotechnological potential as biocontrol agents. However, the nature and interplay ... -
Mycorrhizal benefits on plant growth and protection against Spodoptera exigua depend on N availability
Ramírez-Serrano, Beatriz; Querejeta Coma, Marina; Minchev, Zhivko; Gamir, Jordi; Perdereau, Elfie; Pozo, Maria J.; Dubreuil, Geraldine; GIRON, David Taylor and Francis Group (2022-09-19)Mycorrhizal symbiosis influences plant growth and nutrition and can affect the performance of insect herbivores, but these effects are context-dependent. This study aims to investigate the influence of nitrogen fertilization ... -
Phosphorus availability drives mycorrhiza induced resistance in tomato
dejana, laura; Ramírez-Serrano, Beatriz; Rivero Bravo, Javier; Gamir, Jordi; López-Ráez, Juan A.; Pozo, Maria J. Frontiers Media (2022)Arbuscular mycorrhizal (AM) symbiosis can provide multiple benefits to the host plant, including improved nutrition and protection against biotic stress. Mycorrhiza induced resistance (MIR) against pathogens and insect ... -
The simultaneous perception of self- and non-self-danger signals potentiates plant innate immunity responses
Pastor, Victoria; Cerveró, Raquel; Gamir, Jordi Springer Nature (2022-06-13)Main conclusion: The simultaneous perception of endogenous and exogenous danger signals potentiates PAMP-triggered immunity in tomato and other downstream defence responses depending on the origin of the signal. Plant ... -
Tomato Systemin induces resistance against Plectosphaerella cucumerina in Arabidopsis through the induction of phenolic compounds and priming of tryptophan derivatives
Pastor Fernández, Julia; Sánchez-Bel, Paloma; Gamir, Jordi; Pastor, Victoria; Sanmartín, Neus; Cerezo García, Miguel; Andrés-Moreno, Silvia; Flors, Victor Elsevier ScienceDirect (2022-05-14)Phytocytokines are endogenous danger peptides that are actively released after a pest or pathogen attack, triggering an amplification of plant immune responses. Here, we found that Systemin, a peptide from tomato, has a ... -
Towards understanding of fungal biocontrol mechanisms of different yeasts antagonistic to Botrytis cinerea through exometabolomic analysis
Fernandez San Millan, Alicia; Gamir, Jordi; Larraya, Luis M.; Farran, Inmaculada; Veramendi, Jon Elsevier (2022-11)There is increased interest in research on yeasts as potential phytopathogen biocontrol agents due to increasing restrictions in the use of chemical pesticides. Yeast strains from a range of genera and species have been ...
