Secretome analysis reveals an Arabidopsis lipase involved in defense against Alternaria brassicicola.
The Arabidopsis thaliana secretome was analyzed by the proteomic approach, which led to the identification of secreted proteins implicated in many aspects of cell biology. We then investigated the change in the Arabidopsis secretome in response to salicylic acid and identified several proteins involved in pathogen response. One of these, a secreted lipase with a GDSL-like motif designated GDSL ...
متن کاملArabidopsis PECTIN METHYLESTERASEs contribute to immunity against Pseudomonas syringae.
Pectins, major components of dicot cell walls, are synthesized in a heavily methylesterified form in the Golgi and are partially deesterified by pectin methylesterases (PMEs) upon export to the cell wall. PME activity is important for the virulence of the necrotrophic fungal pathogen Botrytis cinerea. Here, the roles of Arabidopsis PMEs in pattern-triggered immunity and immune responses to the ...
متن کاملCharacterization of the early response of Arabidopsis to Alternaria brassicicola infection using expression profiling.
All tested accessions of Arabidopsis are resistant to the fungal pathogen Alternaria brassicicola. Resistance is compromised by pad3 or coi1 mutations, suggesting that it requires the Arabidopsis phytoalexin camalexin and jasmonic acid (JA)-dependent signaling, respectively. This contrasts with most well-studied Arabidopsis pathogens, which are controlled by salicylic acid-dependent responses a...
متن کاملProteomics of the response of Arabidopsis thaliana to infection with Alternaria brassicicola.
We have studied the proteome of the model plant Arabidopsis thaliana infected with a necrotrophic fungal pathogen, Alternaria brassicicola. The Arabidopsis-A. brassicicola host-pathogen pair is being developed as a model genetic system for incompatible plant-fungal interactions, in which the spread of disease is limited by plant defense responses. After confirming that a defense response was in...
متن کاملArabidopsis cell death in compatible and incompatible interactions with Alternaria brassicicola.
Two strains of necrotrophic Alternaria brassicicola, Ab40857 and Ab42464, are virulent on Korean cabbage and several wild types of Arabidopsis thaliana. Interaction between Ab42464 and Col-0 was compatible, whereas interaction between Ab40857 and Col-0 was incompatible. The loss of defense, no death (dnd) 1 function abrogated the compatibility between Ab42464 and Col-0, and the accelerated cell...
