Cytoplasmic sequestering of a fungal stress-activated MAPK in response to a host plant phenolic acid

Project description:The stress-activated MAPK Hog1 in Cochliobolus heterostrophus, a maize foliar pathogen, undergoes dephosphorylation upon exposure to ferulic acid (FA), a phenolic compound abundant in the host plant. Unlike its nuclear localization during osmotic stress, Hog1:GFP forms cytoplasmic foci in response to FA, indicating its sequestering. By using Hog1:GFP as an affinity purification bait, we isolated an FA-dependent sub-proteome from a subcellular fraction enriched with fluorescent foci. The identified proteins include RNA-binding proteins, translation initiation factors and mitochondrial proteins, suggesting the foci to be stress granules.

Ferulic Acid Challenge of Lactobacillus brevis

Project description:The presence of anti-microbial phenolic compounds, such as the model compound ferulic acid, in biomass hydrolysates poses significant challenges to the widespread use of biomass in conjunction with whole cell biocatalysis or fermentation. Currently, these inhibitory compounds must be removed through additional downstream processing to create feedstock suitable for most industrially important microbial strains. This study explores the high ferulic acid tolerance in Lactobacillus brevis (L. brevis), a lactic acid bacteria often found in fermentation processes, by global transcriptional response analysis. The transcriptional profile of L. brevis under ferulic acid stress reveals that the presence of ferulic acid primarily triggers the expression of membrane proteins to counteract ferulic acid induced changes in membrane fluidity and ion leakage, in the midst of a generalized stress response. Several promising routes for understanding phenolic acid tolerance have been identified based upon these findings. These insights may be used to guide further engineering of model industrial organisms to better tolerate phenolic compounds in processed biomass.

Effect of ferulic acid on Clostridium beijerinckii NCIMB 8052 transcriptome

Project description:The impacts of ferulic acid, a phenolic compound commonly found in lignin hydrolysates, on the growth, solvent production and transcriptional responses of C. beijerinckii NCIMB 8052 were determined. Addition of ferulic acid to growing cultures resulted in a decrease in the growth and solvent production by 30 and 25%, respectively, when compared to the control cultures. To better understand the toxicity of this compound, microarray analyses were performed using samples taken from these cultures at three different growth states. Several gene ontology terms and KEGG pathways were identified showing significant change at each status, including ABC transporters, two component system and oxidoreductase activity. Moreover, genes related with efflux systems and heat shock proteins were also strongly up- regulated. Among these, expression of the groESL operon was induced by more than 4-fold and was consequently selected for overexpression to improve C. beijerinckii tolerance to ferulic acid.

Expression data from ferulic acid treated C. elegans

Project description:Gene expression in N2 worms treated with 500 μM or 0 μM ferulic acid, at days 5. Effects of ferulic acid in C. elegans gene expression is studied, as our results indicate a lifespan extension effect produced by this molecule. RNA-seq were used to detail the global programme of gene expression underlying the lifespan extension and identified distinct classes of up/down-regulated genes in animals treated with ferulic acid.

Global transcriptomic analysis of the response of Corynebacterium glutamicum to ferulic acid

Project description:Corynebacterium glutamicum can survive by using ferulic acid as the sole carbon source. In this study, we assessed the response of C.glutamicum to ferulic acid stress by means of a global transcriptional response analysis. The transcriptional data showed that several genes involved in degradation of ferulic acid were affected. Moreover, several genes related to the stress response; protein protection or degradation and DNA repair; replication, transcription and translation; and the cell envelope were differentially expressed. Deletion of the katA or sigE gene in C. glutamicum resulted in a decrease in cell viability under ferulic acid stress. These insights will facilitate further engineering of model industrial strains, with enhanced tolerance to ferulic acid to enable easy production of biofuels from lignocellulose.

Autotoxicity mechanism of Oryza Sativa: Microarray analysis of rice plants in response to allelochemical ferulic acid

Project description:Autotoxicity plays an important mechanism in regulating plant productivity. Ferulic acid (FA) is phytotoxic and was identified in extracts and residues of rice plants as a candidate for rice allelochemicals. To help characterize the autotoxicity mechanism of rice, we present the first large-scale, transcriptomic analysis of rice root responses to ferulic acid.
