Functional analyses provide evidence for a complex Nod factor signalling where NFRe is necessary for maintaining an optimal symbiotic signalling in the susceptible root zone, and initiation of nodule primordia on the expanding root system.
Ectopic expression of Symbiosis Receptor-like Kinase (SYMRK) in roots of the legume Lotus japonicus resulted in spontaneous activation of nodule organogenesis and mycorrhiza-related gene expression in the absence of microbial symbionts or signalling molecules.
Identification of two arbuscular mycorrhiza-specific lipid biosynthesis mutants and fatty acid transfer experiments reveal that host plant lipids are transferred to symbiotic fungi and needed for their development.
To leverage the tools, resources and knowledge that exist for C. elegans so that we can study ecology, evolution and other aspects of biology, we need to understand the natural history of this important model organism.
Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.
Selective forces imposed by the squid animal host drive rapid adaptation of non-native Vibrio fischeri bacteria through convergent mutations of large effect, unmasking preexisting coordinated regulation of symbiosis.
