Project description:Brown algae (Phaeophyceae) are complex photosynthetic organisms with a very different evolutionary history to green plants, to which they are only distantly related. These seaweeds are the dominant species in rocky coastal ecosystems and they exhibit many interesting adaptations to these, often harsh, environments. The brown algae are also important because they are one of only a very small number of eukaryotic lineages that have evolved complex multicellularity. This work used whole genome tiling array approach to generate a comprehensive transcriptome map of the filamentous seaweed Ectocarpus siliculosus (Dillwyn) Lyngbye, a model organism for the brown algae. Keywords: high-resolution tiling array, brown algae, ectocarpus

This work used whole genome tiling array approach to generate a comprehensive transcriptome map of the filamentous seaweed Ectocarpus siliculosus (Dillwyn) Lyngbye, a model organism for the brown algae. Keywords: high-resolution tiling array, brown algae, ectocarpus The slides were hybridised with two, labelled samples: 1) a mixture of labelled cDNA corresponding to RNA samples from mature sporophytes and gametophytes and from immature sporophytes stressed either in high salt medium or by addition of hydrogen peroxide and 2) genomic DNA as a control.

Project description:The pathosystem between the model brown alga Ectocarpus siliculsosus and the oomycete pathogen Eurychasma dicksonii was investigated with the aim to identify proteins involved in host repsonse. Comparative 2D electrophoresis was used to identify protein spots differentially expressed between uninfected control and infected algal tissue.

Project description:The aim of this study was to analyze genome-wide patterns of histone post-translational modifications (PTMs) and nucleosome distribution during the sporophyte and gametophyte generations of the life cycle of the brown alga Ectocarpus. Analysis of the results of this experiment along with those generated by a second experiment “Genome-wide analysis of chromatin states of Ectocarpus sporophytes and gametophytes, experiment 1” indicated that the histone PTMs H3K4me2, H3K4me3, H3K9ac, H3K14ac and H3K27ac are associated with the transcriptional start sites (TSSs) of actively expressed genes, H3K36me3 preferentially marks gene bodies and is associated with gene activation, H4K20me3 marks transposons and is associated with gene repression, probably through the silencing of transposons in introns. H3K79me2 occurs in zones corresponding to about a third of the genome. These zones often span several genes and genes within H3K79me2 zones exhibit lower levels of transcript abundance.
