Phylogenomics reveals multiple losses of nitrogen-fixing root nodule symbiosis
(American Association for the Advancement of Science, 2018-05)
The root nodule symbiosis of plants with nitrogen-fixing bacteria affects global nitrogen cycles and food production but is restricted to a subset of genera within a single clade of flowering plants. To explore the genetic ...
The tight-adhesion proteins TadGEF of Bradyrhizobium diazoefficiens USDA 110 are involved in cell adhesion and infectivity on soybean roots
(Elsevier Gmbh, 2016-01)
Adhesion of symbiotic bacteria to host plants is an essential early step of the infection process that leads to the beneficial interaction. In the Bradyrhizobium diazoefficiens-soybean symbiosis few molecular determinants ...

(1999-12)
El motivo de este trabajo es ofrecer el primer registro de un escaramujo, observado por el primero de los autores, asociado con corales cubanos, y otro escaramujo encontrado en simbiosis con la esponja Callyspongia vaginalis. ...
Reaction network modeling of complex ecological interactions: endosymbiosis and multilevel regulation
(Wiley-Hindawi, 2021)
Endosymbiosis is a type of symbiosis where one species of microscopic scale inhabits the cell of another species of a larger scale, such that the exchange of metabolic byproducts produces mutual benefit. These benefits can ...
Evolution of Substrate Preparation Behaviors for Cultivation of Symbiotic Fungus in Attine Ants (Hymenoptera: Formicidae)
(Springer/plenum Publishers, 2010-05-01)
Despite their importance for the evolution of the symbiosis between Attine ants and their fungal cultivar, substrate preparation behaviors have been the focus of few studies. This study aimed to comparatively examining ...
Nitrogen-tixing and vesicular-arbuscular mycorrhizal symbioses in some tropical legume trees of tribe Mimoseae
(Elsevier B.V., 2004-07-26)
Response to mineral fertilization and inoculation with rhizobia and/or arbuscular mycorrhiza fungi (AMF) of the Anadenanthera colubrina, Mimosa bimucronata and Parapiptadenia rigida (Leguminosae-Mimosoideae) native trees ...
Assessment of microfungi in fungus gardens free of the leaf-cutting ant Atta sexdens rubropilosa (Hymenoptera: Formicidae)
(2005-10-05)
The purpose of this study was to determine the microfungi present in young nests of Atta sexdens rubropilosa when the fungus gardens were deprived of worker ants. The results were compared with another study in which worker ...
Biological features of a puzzling symbiotic association between the hermit crab Dardanus insignis and the porcellanid crab Porcellana Sayana (Crustacea)
(Elsevier B.V., 2008-07-18)
The symbiotic lifestyle is widespread among porcellanid crabs, which maintain ecological and co-evolutionary associations with annelid polychaetes, poriferans, cnidarians, echinoderms, gastropod. mollusks, and other ...
