Project description:Arthrobacter chlorophenolicus A6 is a 4-chlorophenol degrading soil bacterium with high phyllosphere colonization capacity. Till now the genetic basis for the phyllosphere competency of Arthrobacter or other pollutant-degrading bacteria is uncertain. We investigated global gene expression profile of A. chlorophenolicus grown in the phyllosphere of common bean (Phaseolus vulgaris) compared to growth on agar surfaces. We designed transcriptome arrays and investigated which genes had different transcript levels in the phyllosphere of common bean (Phaseolus vulgaris) as compared to agar surfaces. Since water availability is considered an important factor in phyllosphere survival and activity, we included both high and low relative humidity treatments for the phyllosphere-grown cells. In addition, we determined the expression profile under pollutant exposure by the inclusion of two agar surface treatments, i.e. with and without 4-chlorophenol.

Leaf transcriptomes of Arabidopsis thaliana colonized by representative phyllosphere commensals alone and in combination with the pathogen Pseudomonas syringae DC3000

Project description:Plants are colonized by a variety of microorganisms, the plant microbiota. In the phyllosphere, the above-ground parts of plants, bacteria are the most abundant inhabitants. Most of these microorganisms are not pathogenic and the plant responses to commensals or to pathogen infection in the presence of commensals are not well understood. We report the Arabidopsis leaf transcriptome after 3 to 4 weeks of colonization by Methylobacterium extorquens PA1 and Sphingomonas melonis Fr1, representatives of two abundant genera in the phyllosphere, compared to axenic plants. In addition, we also sequenced the transcriptome of Arabidopsis 2 and 7 days after spray-infection with a low dose of P. syringae DC3000 and in combination with the commensals.

Analysis of gene expression in leaves of Medicago truncatula plants inoculated with arbuscular mycorrhizal fungi and plants fertilized with phosphate

Project description:Arbuscular mycorrhizas (AM) are the most common symbiotic associations between plant’s root compartment and fungi. They can provide both nutritional benefit (mostly inorganic phosphate) leading to improved growth and non-nutritional benefits including defense responses to environmental cues throughout the host plant, which in return delivers carbohydrates to the symbiont. However how transcriptional changes occurring in AM leaves differ from those induced by phosphate fertilization is poorly understood. We investigated systemic changes in the leaves of mycorrhized Medicago truncatula compared to non-mycorrhized control plants, and in phosphate fertilized plants compared to control plants.
