Zusammenfassung:
Seaweed aquaculture is increasingly attracting interest in Europe and the USA as a potential means to increase future production of food and biomass. Efficient expansion of seaweed cultivation to meet this objective will require the implementation of modern breeding strategies to improve yields and crop resilience. We have been developing several resources that are relevant to this objective. First, the large-scale brown algal genome sequencing project Phaeoexplorer (https://phaeoexplorer. sb-roscoff.fr/home/) is generating genome sequence information for several species of interest for aquaculture. These genomes represent essential reference sequences for future breeding programs. Second, recently established resources for the model brown alga Ectocarpus, in particular CRISPR-based gene editing, now make it a powerful tool for the analysis of gene function. Experimentally validated information about gene function obtained using this system will also be extremely useful to help target breeding approaches. Finally, focusing on the sugar kelp Saccharina latissima as a target aquaculture species, we have been establishing a range of resources including a large collection of RAD-seq genotyped gametophyte strains and protocols for the application of quantitative trait locus analysis and genome-wide association studies. The presentation will provide an overview of these approaches and will discuss their integration into seaweed breeding programs.
