Bacterial pathogens, virulence mechanism and host defence in marine macroalgae. Following the recognition of microbes, evidence has emerged for the occurrence and significant role of innate immunity processes as the first line of defense in seaweeds, similarly to that observed in vascular plants and metazoans 10— 13including transient production of reactive oxygen species ROS 14— Finally, we verified the upregulation of genes associated with energy metabolism, indicating that the defense mechanisms in L.

Demographic consequences of disease in a habitat-forming seaweed and impacts on interactions between natural enemies. In contrast, the downregulation of genes biologa in energy conversion was detected, through a microarray, after the cresp of Chondrus crispus to methyl jasmonate Laurencia is a red seaweed genus widely distributed around the world, recognized for the biosynthesis of diverse halogenated secondary metabolites, especially terpenes, with relevant ecological 2324 and pharmacological 25— 29 activities.

Because ROS can react with essential host molecules, the activity of antioxidant enzymes is important to limit the oxidative burst. Early events crrespo the biologiz of lipopolysaccharides in the brown alga Laminaria digitata include an oxidative burst and activation of fatty acid oxidation cascades.

It is also necessary to determine if the measured differences represented a generic response of Laurencia to bacteria or a response to a specific potential pathogen. Patterns of gene expression induced by oligoguluronates reveal conserved and environment-specific molecular defense responses in the brown alga Laminaria digitata.

The unialgal culture of this seaweed was established through successive excision of the apices. This is an open-access article distributed under the terms of the Creative Commons Attribution 4. Further, we observed the upregulation of L. Received Mar 3; Accepted Nov pereirra. Free fatty acids and methyl jasmonate trigger defense reactions in Laminaria digitata. Vibrio madracius was isolated from the coral Madracis decactis sampled in Saint Peter and Saint Bioogia archipelago Ding H, Biologua J.


The innate immunity of a marine red alga involves oxylipins from both the eicosanoid and octadecanoid pathways. This report contributes significantly to the current knowledge about the molecular mechanisms involved in the highly dynamic seaweed-bacterium interactions.

By expanding knowledge about seaweed-bacterium interactions and about the integrated defensive system in seaweeds, this work offers the basis for the development of tools to increase the resistance of cultured seaweeds to bacterial infections. Highly dynamic exon shuffling in candidate pathogen receptors … what if brown algae were capable of adaptive immunity?

Int J Syst Evol Microbiol Kelps feature systemic defense responses: J Genet Genomics In this context, the ability of seaweeds to recognize microbes and, when necessary, activate defense mechanisms is essential for their survival. Terpenoid compounds are recognized as important secondary metabolites acting to defend Laurencia species against bacterial colonization Occasional pathogenic bacteria promoting ice-ice disease in the carrageenan-producing red algae Kappaphycus alvarezii and Eucheuma denticulatum Solieriaceae, Gigartinales, Rhodophyta.


Further, the pereora of genes related to the biosynthesis of terpenes, along with the overexpression of genes involved in vesicular transport, suggests increased release of terpenes by L.
