Compartmentalization drives the evolution of symbiotic cooperation
Philosophical Transactions of the Royal Society of London. Biological Sciences, 2020 Across the tree of life, hosts have evolved mechanisms to control and mediate interactions with symbiotic partners. We suggest that the evolution of physical structures that allow hosts to spatially separate symbionts, termed compartmentalization, is a ...

Correction of UBV Photometry for Emission Lines
Open Astronomy, 2003 We investigate the effect on U,B,V magnitudes of the removal of emission lines from the spectra of some symbiotic stars and novae during their nebular phases.

Genetic and Molecular Mechanisms Underlying Symbiotic Specificity in Legume-Rhizobium Interactions
Frontiers in Plant Science, 2018 Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be ...

A double-blind, randomized, placebo-controlled, single-center, pilot study evaluating the role of a L. rhamnosus GG-based symbiotic formulation in patients with mild-to-moderate uc in clinical and endoscopic remission [PDF]
Microbiota in Health and DiseaseObjective: Intestinal dysbiosis is considered a key factor in the pathogenesis and disease progression of ulcerative colitis. Probiotics, prebiotics, and symbiotics are promising strategies for microbiota modulation and could play a role as “add-on ...
