Isolation and characterization of a fucoidan-degrading marine bacterium. ABSTRACT The ability to recognize and respond pereirw the presence of microbes is an essential strategy for seaweeds to survive in the marine environment, but understanding of molecular seaweed-microbe interactions is limited.

Intra-cellular storage, transport and exocytosis of halogenated compounds in marine red alga Laurencia obtusa. Nonetheless, the direct effects of microorganisms on seaweed gene expression have rarely been evaluated and have relied on real-time PCR techniques, monitoring a limited number of genes 49 The MAPK cascade transduces extracellular stimuli into intracellular responses during plant defense against pathogens and can induce the expression of defense-related genes through the phosphorylation of transcription factors, such as ERF Ethene ethylene production in the marine macroalga Ulva Enteromorpha intestinalis L.

This report contributes significantly to the current knowledge about the molecular mechanisms involved in the highly dynamic seaweed-bacterium interactions. Innate immunity in plants and animals: J Nat Prod Support Center Support Center.

Annu Rev Phytopathol Numbers of genes shared among control samples left, 7 samples and samples of Laurencia dendroidea inoculated with Vibrio madracius rdnato, 8 samples. Several genes related to the biosynthesis of terpenes were also upregulated in L. Plant Cell Physiol Occasional pathogenic bacteria promoting ice-ice disease in the carrageenan-producing red algae Kappaphycus alvarezii and Eucheuma denticulatum Solieriaceae, Gigartinales, Rhodophyta.

Finally, we verified the upregulation of genes associated with energy metabolism, indicating that the defense mechanisms in L. Seaweeds are extremely susceptible to microbial colonization due to the release of large amounts of carbon compounds that act as chemical attractants and nutrient sources for bacteria 1.

Signaling cascades that modulate the innate immune response have been well described in plants but are still unknown in seaweeds. The unialgal culture of this seaweed was established through successive excision of the apices.

The present report shows that even though V. Marinhw evaluate the transcriptomic profile of L. Bacterial pathogens, virulence mechanism and host defence in marine macroalgae. 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.

Calcium-dependent protein kinases play an essential role in a plant defence response. Genes coding for defense-related transcription activators, reactive oxygen species metabolism, terpene biosynthesis, and reanto conversion pathways were upregulated in inoculated samples of L.
