Project description:Kelp are the largest photosynthetic organisms in the ocean with tissue differentiation and complex life cycles. Other multicellular organisms with similar complexity such as plants and animals are well known to posses epigenetic mechanisms such as DNA methylation to control development and morphogenesis. Despite plant-like body plans and the presence of different life-cycle stages, the kelp species Saccharina japonica has only a very low level of DNA methylation, yet we have found strong evidence for differential methylation of regulatory elements and protein-coding genes which seem to contribute to the formation of life-cycle stages, tissue differentiation, growth and halogen metabolism. Thus, DNA methylation seems to play an important role in kelp, which has not been reported before.
Project description:We performed a laboratory experiment with vegetative gametophytes of the kelp Saccharina latissima and exposed the gametophytes to three temperatures (4°C, 12°C and 20°C) by sex (female, male) for 14 days.
Project description:Rising atmospheric CO2 concentrations are leading to ocean acidification, altering the inorganic carbon buffer system with consequences for marine organisms. Here we applied RNA-seq and iTRAQ quantification to investigate the potential impacts of ocean acidification on the temperate coastal marine diatom Skeletonema marinoi.
Project description:Long chain sulfated polysaccharides such as fucoidans are promising feed additives to improve animal health and welfare. Thus, our study evaluated the bioactive properties of a fucoidan-enriched fraction from sugar kelp (Saccharina lattissima) on the intestinal transcriptome of pre-smolts Atlantic salmon (Salmo salar) fed with novel functional aquafeeds for 5 weeks in freshwater.

Project description:Bull kelp and giant kelp population genomics
Project description:ATAC-seq was used to locate putative enhancer regions in the early development (tailbud stage), developing male and female gonads of the marine chrodate Oikopleura dioica.
Project description:ChIP-seq was used to generate chromatin state maps, profile binding patterns of key architectural proteins and locate putative enhancer regions in the early development (TB stage) and developing gonads of the marine chrodate Oikopleura dioica.
Project description:Capitella teleta is a model specie in marine annelids research, to gain insight into its development, we performed time-course ATAC-seq ranging from 64 cell to stage 8 larvae, to profiling the gene regulation dynamics
