Project description:We addressed the question how the interaction between the beneficial root endophyte Serendipita vermifera (Sv) and the pathogen Bipolaris sorokiniana (Bs) affects fungal behavior and determines barley host responses using a gnotobiotic natural soil-based split-root system for phenotypic and transcriptional analyses.
Project description:MafF-/-: MafG+/+: MafK-/- mice are viable, while MafF-/-: MafG-/-: MafK-/- mice are embryonic lethal. To get an insight into the cause of the lethality of small Maf triple knockout mice, transcriptome analysis was performed using whole embyos of MafF-/-: MafG-/-: MafK-/- at E10.5 and those of MafF-/-: MafG+/+: MafK-/- at E9.5 or E10.5. Because MafF-/-: MafG-/-: MafK-/- embryos exhibit growth retardation, the gene expression profile of MafF-/-: MafG-/-: MafK-/- embryos at E10.5 was compared with that of MafF-/-: MafG+/+: MafK-/- embyos at E9.5. The gene expression profile of MafF-/-: MafG+/+: MafK-/- embryos at E10.5 was also examined as an alternative control. Total RNA was prepared from pooled three embryos for each sample.

Project description:Illumina HiSeq technology was used to generate mRNA profiles from Sebacina vermifera mycorrhizal roots compared to free-living mycelium . Mycorrhizal roots were harvested after 3, 7 and 14 days, pooled and used for RNA extraction. Reads of 2X100bp were generated and aligned to Sebacina vermifera (http://genome.jgi-psf.org/Sebve1/Sebve1.home.html) using CLC Genomics Workbench 6. mRNA profiles from Sebacina vermifera mycorrhizal roots and free-living mycelium were generated by paired-end (2x100bp) Illumina HiSeq2000 sequencing. Three biological replicates were sequenced for mycorrhizal and mycelium samples.
Project description:We sought to characterize the proteome and metabolome of S. vermifera and S. bescii under N and P starvation conditions in vitro. As very little is known about the ecological functioning of the Serendipitaceae in most environments, the overall objective of the study was to elucidate the cellular response(s) of two Serendipitaceae strains toward stress imposed by the lack of one or the other of these important nutrients. Our approach allows us to not only evaluate N and P acquisition processes in the understudied Serendipitaceae, but also to understand the physiological responses to their restriction.
