Separate jasmonate-dependent and salicylate-dependent defense-response pathways in Arabidopsis are essential for resistance to distinct microbial pathogens.
TLDR
Data point to the existence of at least two separate hormone-dependent defense pathways in Arabidopsis that contribute to resistance against distinct microbial pathogens. Expand
Pathogen-induced systemic activation of a plant defensin gene in Arabidopsis follows a salicylic acid-independent pathway.
TLDR
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. Expand
Concomitant Activation of Jasmonate and Ethylene Response Pathways Is Required for Induction of a Plant Defensin Gene in Arabidopsis
TLDR
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. Expand
Deficiency in phytoalexin production causes enhanced susceptibility of Arabidopsis thaliana to the fungus Alternaria brassicicola.
TLDR
Camalexin production could not be triggered by exogenous application of either salicylate, ethylene or jasmonate and was not, or not strongly, reduced in mutants with defects in perception of these defense-related signal molecules, which appears to be a key determinant in resistance to at least A. brassicicola.

Analysis of two novel classes of plant antifungal proteins from radish (Raphanus sativus L.) seeds.
TLDR
The radish 2S storage albumins were identified as the second novel class of antifungal proteins that inhibit growth of different plant pathogenic fungi and some bacteria, however, their antimicrobial activities are strongly antagonized by cations. Expand
Requirement of functional ethylene-insensitive 2 gene for efficient resistance of Arabidopsis to infection by Botrytis cinerea.
TLDR
The data support the conclusion that ethylene-controlled responses play a role in resistance of Arabidopsis to some but not all types of pathogens. Expand
Plant Defensins: Novel Antimicrobial Peptides as Components of the Host Defense System
TLDR
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. Expand
The role of ethylene in host-pathogen interactions.
TLDR
The phytohormone ethylene is a principal modulator in many aspects of plant life, including various mechanisms by which plants react to pathogen attack, and cross-talk occurs with other defense response pathways controlled by salicylic acid and jasmonate, eventually resulting in a differentiated disease response. Expand
An automated quantitative assay for fungal growth inhibition
TLDR
A straight-line relationship exists between absorbance at 595 nm and dry weight of microplate cultures, indicating that culture absorbance is an accurate indicator of fungal biomass. Expand
The complexity of disease signaling in Arabidopsis.
TLDR
This work has shown that the plant defense system is regulated through a complex network of various signaling cascades that regulates a multicomponent defense response. Expand
