partners in arbuscular mycorrhizal
symbioses lack the genes for enzymes involved in the major pathway of lipid biosynthesis, and are therefore unable to produce certain essential fatty acids,» Gutjahr explains.
Recent findings emphasize the importance of investigating members of the archaeal domain of life in order to obtain a more comprehensive view of microbial ecology,
symbiosis, and metabolic interdependencies involving archaeal
partners, and of evolution of life on Earth in regard to the deep roots of archaea as well as our microbial ancestry.
A better understanding of the role of lipid biosynthesis in this type of
symbiosis could therefore help to select host plants that can make optimal use of their relationship with their fungal
partners, which can be a benefit to sustainable agriculture.

symbiosis between beewolves and their bacterial

The exhibition focuses on Moser's architectural work in its unusually close relationship with the visual arts, a complex
