Abstract
The addition of the red seaweed Asparagopsis taxiformis into cattle diet is a promising strategy to reduce methane emissions derived from cattle rumen. This is primarily attributed to bromoform, a halogenated compound which is stored by A. taxiformis in specialised vesicles (or gland cells) and can interfere with methane biosynthesis within rumen. Consequently, the farming of A. taxiformis is set to expand and the developments will likely include land-based cultures of A. taxiformis tetrasporophytes in closed systems. Nevertheless, despite the growing potential of A. taxiformis as an aquaculturally significant species, there are currently various bottlenecks that prevent its farming at large scale. One of these bottlenecks includes a lack of understanding, particularly at a molecular level, of the biology of this organism under culture conditions. Gaining such knowledge may be valuable for future A. taxiformis aquaculture developments and provides novel insights into the ecology of this widespread seaweed. Therefore, the main objective of this Thesis was to investigate the molecular principles of intraspecific interactions within the entire A. taxiformis holobiont (i.e. seaweed host and its associated microbiome).
