Out of Water: The Origin and Early Diversification of Plant R-Genes
During plant-pathogen interactions, plants use intracellular proteins with nucleotide-binding site and leucine-rich repeat (NBS-LRR) domains to detect pathogens. NBS-LRR proteins represent a major class of plant disease resistance genes (R-genes). Whereas R-genes have been well characterized in a...
Why did filamentous plant pathogens evolve the potential to secrete hundreds of effectors to enab...
During the past decade, many genomes have been sequenced from fungal and oomycete pathogens that interact biotrophically with plants, i.e. they thrive at least initially on living plant tissue. This has revealed genomes that often encode hundreds of proteins predicted to be secreted on the basis ...
Disease-induced assemblage of a plant-beneficial bacterial consortium
Disease suppressive soils typically develop after a disease outbreak due to the subsequent assembly of protective microbiota in the rhizosphere. The role of the plant immune system in the assemblage of a protective rhizosphere microbiome is largely unknown. In this study, we demonstrate that Arab...
Major New Microbial Groups Expand Diversity and Alter our Understanding of the Tree of Life
The tree of life is arguably the most important organizing principle in biology and perhaps the most widely understood depiction of the evolutionary process. It explains to us how we are related to other organisms and where we may have come from. The tree has undergone some tremendous revolutions...
Ericoid plant species and Pinus sylvestris shape fungal communities in their roots and surroundin...
Root-colonizing fungi can form mycorrhizal or endophytic associations with plant roots, the type of association depending on the host. We investigated the differences and similarities of the fungal communities of three boreal ericoid plants and one coniferous tree, and identified the community st...
