Stenmark H, Olkkonen VM. Despite being part of the defensive strategy renzto seaweeds against fouling 20the presence of ROS can damage the seaweed cell structures, so the oxidative burst must be tightly regulated through the activation of antioxidant enzymes The conflicting results could be attributed to intrinsic biological differences between the two species or to the relatively small number of sequences analyzed.

A recent study demonstrated the occurrence of genes coding for LRR kinases in the brown seaweed Ectocarpus siliculosus that, due to their molecular structure, were considered to represent candidate pathogen receptors Members of the family Epialtidae are usually herbivores that mask themselves with pieces of seaweed and other materials to avoid predation. ABSTRACT The ability to recognize and respond to 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.

Nucleic Acids Res The present report contributes to evidence maringa the presence of a mechanism in seaweeds similar to plant hormone-regulated defense against microbes.

To creslo the transcripts associated with the biosynthesis of terpenoid compounds, we analyzed the transcriptome of L. Besides being directly toxic to microbes 17ROS participate in intracellular signaling mechanisms leading to the activation of other defense responses 18such as the expression of genes related to the biosynthesis of secondary metabolites If this holds true, lowlight stress should reduce the ability of seaweeds to defend themselves chemically against herbivory and fouling.
