Project description:Narcosis or baseline toxicity is the inert toxicity of hydrophobic compounds, supposed to take place at the level of the cellular membranes. Based on the linear relationship between the toxicity (logEC50) and the hydrophobicity (logKow), class I and II narcotizing compounds are recognized, in which the latter group is assumed to exert additional toxic mechanisms by hydrogen bond donor acidity by their polar groups. Chlorinated anilines, which occur often in the environment as degradation products of certain pesticides , are considered to be narcotizing compounds. In this study the transcriptional responses of the soil arthropod Folsomia candida are investigated upon exposure to a series of anilines with increasing chlorination. A discrimination between class1 and class2 narcotizing compound is being made.

In this study the transcriptional responses of the soil arthropod Folsomia candida are investigated upon exposure to a series of anilines with increasing chlorination. A discrimination between class1 and class2 narcotizing compound is being made. Twenty-three day old Folsomia candida were exposed in LUFA 2.2 standard soil for two days to the EC50 concentrations of the following compounds: aniline, 4-chloroaniline, 3.5-dichloroaniline, 2,3,4-trichloroaniline, 2,3,5,6-tetrachloroaniline, pentachloroaniline and 1,2,3,4-tetrachlorobenzene.1,2,3,4-tetrachlrobenzene was included in the experimental design as a posiitive control of a narcotic class 1 compound. Four biological replicates were used for every treatment and a dye swap was used with the Cy3/Cy5 labels. This resulted in 32 samples which were analysed in 16 hybridisations executed in an interwoven loop design. The solvent (for spiking the soil) control was used as the reference treatment in the data analysis.

Project description:The present invention relates to methods for determining soil quality, and especially soil pollution, using the invertebrate soil organism Folsomia candida also designated as springtail. Specifically, the present invention relates to a method for determining soil quality comprising: contacting Folsomia Candida with a soil sample to be analysed during a time period of 1 to 5 days; isolating said soil contacted Folsomia Candida; extracting RNA from said isolated soil contacted Folsomia Candida; determing a gene expression profile based on said extracted RNA using microarray technology; comparing said gene expression profile with a reference gene expression profile; and determing soil quality based expression level differences between said gene expression profile and said control expression profile.

A direct design was used where springtails were exposed to 3 field soils (2 polluted and 1 clean) and cadium and microarrays were directly contrased to those from animals exposed to clean LUFA2.2 soil. 4 biological replicates were used with each containing 25 grams of soil and 30 adult, randomly selected, age sychronized springtails

Project description:Folsomia candida (Collembola) is able to survive dryer conditions by absorbing water vapour from its surroundings. To unravel the genomic responses underlying this intriguing water-absorption mechanism, we exposed the species to 98.2% Relative Humidity (eight, 27, 53 and 174 hours respectively) and subjected it to microarray based transcription profiling.
