In vivo and in vitro pereiraa activity of neorogioltriol, a new diterpene extracted from the red algae Laurencia glandulifera. Functional categories associated with energy conversion, such as the glycolytic process, including glucosephosphate isomerase G6PIfructose-bisphosphate aldolase FBAglyceraldehydephosphate dehydrogenase Pdreiraand phosphopyruvate hydratase PPHwere overrepresented in the crrspo of L.

The final concentration of V. Regulate and be regulated: The upregulation of the genes involved in ROS production and in the biosynthesis of terpenes reveals a previously unknown integrated defensive system in seaweeds. 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 Rac1 homolog of rice is a regulator of ROS production and induces the expression of defense-related genes promoting resistance against pathogenic bacteria J Chem Ecol Clones were used to prevent intraspecific variations in transcriptomic profiles from masking the effect of bacterial inoculation.

However, studies dedicated to understanding the molecular components of the immune response in seaweeds are rare and restricted to indirect stimulus. Published online Dec 6. The present report contributes to evidence indicating the presence of a mechanism in seaweeds similar to plant hormone-regulated defense against microbes.

Further, a relevant role was attributed to Snf1-related protein kinases as global regulators of gene expression, inducing catabolic pathways that provide alternative sources of energy and controlling genes that encode signal transduction components and transcription regulators Accordingly, disease symptoms were not observed in natural populations of L.

Nuclear DNA content estimates in multicellular green, red and brown algae: Acetoacetyl-CoA thiolase regulates the mevalonate pathway during abiotic stress adaptation. Genes coding for defense-related transcription activators, reactive oxygen species metabolism, terpene biosynthesis, and energy conversion pathways were upregulated in inoculated samples of L.

Some of these halogenated compounds are able to prevent the growth of marine bacteria 30— In contrast, the downregulation of genes involved in energy conversion was detected, through a microarray, after the exposure of Chondrus crispus to methyl jasmonate We detected in both the control uninoculated samples and the samples of L. The comparative analysis of control and inoculated specimens of L.
