Absence of Cu–Zn superoxide dismutase BCSOD1 reduces Botrytiscinerea virulence in Arabidopsis and tomato plants, revealinginterplay among reactive oxygen species, callose and signallingpathways
Fernández Crespo, Emma; López Cruz, J.; Crespo Salvador, Óscar; García Agustín, Pilar; González-Bosch, Carmen Wiley (2017)Plants activate responses against pathogens, including the oxida-tive burst.

Functional analysis of endo-1,4-b-glucanases in response to Botrytis cinerea and Pseudomonas syringae reveals their involvement in plant–pathogen interactions
Finiti, Iván; Leyva, María de la O; López Cruz, J.; Calderan Rodrigues, B.; Vicedo, Begonya; Angulo, C.; Benett, A. B.; Grant, M.; García Agustín, Pilar; González-Bosch, Carmen 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 is a resistance inducer that protects tomato plants against Pseudomonas syringae by priming the jasmonic acid and salicylic acid pathways.
Scalschi, Loredana; Vicedo, Begonya; Camañes, Gemma; Fernández Crespo, Emma; Lapeña, Leonor; González-Bosch, Carmen; García Agustín, Pilar John Wiley & Sons (2013)Hexanoic acid-induced resistance (Hx-IR) is effective against several pathogens in tomato plants. Our study of the mechanisms implicated in Hx-IR against Pseudomonas syringae pv. tomato DC3000 suggests that hexanoic acid ... -
