Journal ArticleDOI
Separate jasmonate-dependent and salicylate-dependent defense-response pathways in Arabidopsis are essential for resistance to distinct microbial pathogens
Bart P. H. J. Thomma,Kristel Eggermont,Iris A. M. A. Penninckx,Brigitte Mauch-Mani,Ralph Vogelsang,Bruno P. A. Cammue,Willem F. Broekaert +6 more
TL;DR: Data point to the existence of at least two separate hormone-dependent defense pathways in Arabidopsis that contribute to resistance against distinct microbial pathogens.
Journal ArticleDOI
Concomitant activation of jasmonate and ethylene response pathways is required for induction of a plant defensin gene in Arabidopsis.
Iris A. M. A. Penninckx,Bart P. H. J. Thomma,Antony Buchala,Jean-Pierre Métraux,Willem F. Broekaert +4 more
TL;DR: It is concluded that both the ethylene and jasmonate signaling pathways need to be triggered concomitantly, and not sequentially, to activate PDF1.2 upon pathogen infection.
Journal ArticleDOI
Pathogen-induced systemic activation of a plant defensin gene in Arabidopsis follows a salicylic acid-independent pathway.
Iris A. M. A. Penninckx,Kristel Eggermont,Franky R. G. Terras,Bart P. H. J. Thomma,G.W. de Samblanx,Antony Buchala,Jean-Pierre Métraux,John Michael Manners,Willem F. Broekaert +8 more
TL;DR: The results indicate that systemic pathogen-induced expression of the plant defensin gene in Arabidopsis is independent of salicylic acid but requires components of the ethylene and jasmonic acid response.
Journal ArticleDOI
Plant defensins: novel antimicrobial peptides as components of the host defense system.
TL;DR: A novel class of plant peptides whose structural and functional properties resemble those of insect and mammalian defensins are characterized, which are one class among the numerous types of Cys-rich antimicrobial peptides.
Journal ArticleDOI
The elderberry (Sambucus nigra L.) bark lectin recognizes the Neu5Ac(alpha 2-6)Gal/GalNAc sequence.
Naoto Shibuya,Irwin J. Goldstein,Willem F. Broekaert,Makuta Nsimba-Lubaki,Benjamin Peeters,Willy J. Peumans +5 more
TL;DR: Carbohydrate binding properties of a new plant lectin isolated from elderberry bark were studied using the techniques of quantitative precipitation, hapten inhibition, and equilibrium dialysis, suggesting the presence of a hydrophibic interacting region adjacent to the carbohydrate binding site.
