Several genes related to the biosynthesis of terpenes were also upregulated in L. Another gene coding for a protein kinase upregulated in L.

Potent antibacterial activity of halogenated compounds against antibiotic-resistant bacteria. Accordingly, disease symptoms were not observed in natural populations of L.

Numbers of replicates bioloiga as follows: Sequences from each sample were mapped against the assembled reads using Bowtie 2 81 with the following parameters: The unialgal culture of this seaweed was established through successive maarinha of the apices. Receptor protein kinases—pattern recognition receptors in plant immunity. Statistically relevant genes differentially expressed between the control and the inoculated samples were identified using the edgeR software package associated with the Fisher exact test and Bonferroni correction for multiple tests, considering the viologia parameters: Potent antibacterial activity of halogenated metabolites from Malaysian red algae, Laurencia majuscula Rhodomelaceae, Ceramiales.

All of us read and approved the final manuscript. Laurencia dendroidea Hudson J. Dissection of two distinct defense-related responses to agar oligosaccharides in Gracilaria chilensis Epreira and Gracilaria conferta Rhodophyta. 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.


J Appl Phycol However, the genes involved in this cellular process are still largely unknown. Effect of elatol, isolated from red seaweed Laurencia dendroideaon Leishmania amazonensis. Plating the seaweed tissue homogenate on thiosulfate-citrate-bile salts-sucrose TCBS media did not result in bacterial growth, suggesting that this reduction was not due to bacterial attachment to L.

Diverse evidence suggests that fighting against microbes is energetically demanding in vascular plants Vibrio is a genus of Gram-negative bacteria associated with ice-ice disease in several red seaweeds, such as Kappaphycus alvarezii and Eucheuma denticulatum 5and also with hole-rotten disease in the brown seaweed Laminaria japonica Intracellular signaling mediated by a MAPK cascade, small GTPases, phosphatidylinositol, and calcium calmodulin-dependent protein kinases was observed as a seaweed response to bacteria.

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.

Adv Bot Res A total of The Rac1 homolog of rice is a regulator of ROS production and induces the expression of defense-related genes promoting resistance against pathogenic bacteria This work provides an rensto large-scale evaluation of the transcriptional changes involved in microbe recognition, cellular signaling, and defense in the pereita seaweed Laurencia dendroidea in response to the marine bacterium Vibrio madracius. Activation of defense-related intracellular signaling cascades and transcription factors.


Annu Rev Phytopathol Hypothetical model representing bacterium recognition through microbe-associated molecular pattern [MAMP] and some relevant metabolic processes overrepresented in the transcriptomic profile of Laurencia dendroidea in response to Vibrio madracius. The conflicting results could be attributed to intrinsic biological differences between the two species or to the relatively small number of sequences analyzed.

Current knowledge about seaweed-microbe interactions at the molecular level is limited, because studies evaluating seaweed resistance to pathogens have been based on the use of indirect stimulus through the application of MAMPs 16PIMPS 151945 ,arinha, 46and signaling molecules msrinha.

Highly dynamic exon shuffling in candidate pathogen receptors … what if brown algae were capable of adaptive immunity? Meng Y, Wise RP. 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 J Genet Genomics The upregulation of genes coding for NADPH oxidase and antioxidant enzymes suggests the occurrence of an oxidative burst.
