متن کاملDoes plant immunity play a critical role during initiation of the legume-rhizobium symbiosis?
Plants are exposed to many different microbes in their habitats. These microbes may be benign or pathogenic, but in some cases they are beneficial for the host. The rhizosphere provides an especially rich palette for colonization by beneficial (associative and symbiotic) microorganisms, which raises the question as to how roots can distinguish such 'friends' from possible 'foes' (i.e., pathogen...
متن کاملRhizobium Symbiosis: Insight into Nod Factor Receptors
The symbiotic association between Rhizobia and legume plants leads to the formation of nitrogenfixing nodules, conferring on host plants the ability to be grown without the addition of nitrogen fertiliser. This symbiosis is characterised by a high level of host specificity, mediated by specific recognition of rhizobial molecules called Nod factors [1]. These are lipochito-oligosaccharides, base...
متن کاملRhizobium symbiosis: nod factors in perspective.
Rhizobium and its allies (Azorhizobium, Bradyrhizobium, and Sinorhizobium) are Gram-negative bacteria that cause the development of root (and sometimes stem) nodules on plant hosts, which the bacteria inhabit as nitrogen-fixing endosymbionts. The early stages of this process, including gene expression in the bacterium and cell growth, division, and differentiation in the host, are mediated by s...
