Does salinity affect lifestyle switching in the plant pathogen Fusarium solani?

Project description:Symbiotic microbes that live within plant hosts can exhibit a range in function from mutualistic to pathogenic, but the reason for this lifestyle switching remains largely unknown. Here we tested whether environmental stress, specifically salinity, is a factor that can trigger lifestyle switching in a fungus mainly known as a pathogen, Fusarium solani. F. solani was isolated from roots of Phragmites australis (common reed) in saline coastal marshes of Louisiana, USA, and we used Oryza sativa (rice) as a model organism from wetland environments to test the symbiont lifestyle. We plated rice seeds on control plates or plates with F. solani at three levels of salinity (0, 8 and 16 p.p.t.), then assessed germination and seedling growth after 20?days. Salinity strongly reduced percentage germination, slowed the timing of germination and reduced growth of rice. F. solani slowed germination, and it also caused a minor increase in root growth at medium salinity and a minor decrease in root growth at high salinity. Overall, despite being a common pathogen in other crop species (peas, beans, potatoes and many types of cucurbits), we found little evidence that F. solani has a strong pathogenic lifestyle in rice and we found weak evidence that pathogenicity may increase slightly with elevated salinity. These results have implications for both crops and native plant health in the future as soil salinization increases worldwide.

Reactive oxygen species (ROS) production triggers unconventional secretion of antioxidant enzymes

Project description:Nutrient deprivation triggers the release of signal-sequence-lacking antioxidant superoxide dismutase 1 (SOD1). We now report that secreted SOD1 is functionally active and accompanied by export of other antioxidant enzymes such as thioredoxins, (Trx1 and Trx2) and peroxiredoxin Ahp1. Our data reveal that starvation increases mitochondrial activity, which generates higher, but non-toxic, levels of reactive oxygen species (ROS). Inhibiting mitochondrial activity or ROS prevents antioxidants secretion. We suggest that in response to ROS production that can permeate the plasma membrane, the cells respond by secreting antioxidants to prevent ROS-mediated damage in the extracellular space. These findings provide an understanding of why cells secrete signal sequence lacking antioxidant enzymes in response to starvation.

Production and Selectivity of Key Fusarubins from Fusarium solani due to Media Composition.

Project description:Natural products display a large structural variation and different uses within a broad spectrum of industries. In this study, we investigate the influence of carbohydrates and nitrogen sources on the production and selectivity of production of four different polyketides produced by Fusarium solani, fusarubin, javanicin, bostrycoidin and anhydrofusarubin. We introduce four different carbohydrates and two types of nitrogen sources. Hereafter, a full factorial design was applied using combinations of three levels of sucrose and three levels of the two types of nitrogen. Each combination displayed different selectivity and production yields for all the compounds of interest. Response surface design was utilized to investigate possible maximum yields for the surrounding combinations of media. It was also shown that the maximum yields were not always the ones illustrating high selectivity, which is an important factor for making purification steps easier. We visualized the production over time for one of the media types, illustrating high yields and selectivity.

The cellulase of Fusarium solani. Resolution of the enzyme complex.

Project description:1. Culture filtrates from Fusarium solani were fractionated by ion-exchange chromatography on DEAE-Sephadex, followed by gel chromatography on Sephadex G-100, into a C(1) component, a C(x) component (CM-cellulase) and a beta-glucosidase (cellobiase) component. 2. The individual components showed little capacity for the solubilization of cotton fibre (cellulase activity), but when recombined in their original proportions 81% of the original cellulase activity was recovered. 3. The C(1) components of F. solani and Trichoderma koningii were similar in their pH optima, heat stabilities over the pH range 5-8 and elution volumes on Sephadex G-100. 4. The C(1) component of F. solani synergized with the C(x) component of T. koningii and conversely. 5. The C(1) and the beta-glucosidase components of F. solani were devoid of the swelling-factor (S-factor) activity associated with the C(x) component.
