Tripartite Symbiotic System of pea (Pisum sativum L.): Applications in Sustainable Agriculture

Advances in Host Plant and Rhizobium Genomics to Enhance Symbiotic Nitrogen Fixation in Grain Legumes

“…For peas, an older set of mutants was used in breeding and a new cultivar "Triumph," originating from a cross between the commercial cultivar "Classic" and a donor of symbiotic effectiveness traits (K-8274) exhibited high grain yield and potential for legume-rhizobia-mycorrhizal symbioses. It was released in the central region of the Russia (Borisov et al, 2008). More recently, Sidorova et al (2011) found dominant symbiotic pea mutants, which are characterized by their high grain yield and nitrogen fixation.…”

Microbiology is the basis of sustainable agriculture: an opinion

“…The pea cultivar Triumph has been created via the ‘inbred‐backcross line’ strategy with wild genotypes used as the donors of high symbiotic activity traits. The cultivar is capable of completing its N and P nutrition after the application of composite inoculants (rhizobia + VAM‐fungi + rhizosphere bacteria) and represents an example of a plant genotype that has the potential for sustainable, microbe‐based crop production (Borisov et al , 2008). As the majority of legume Sym genes have evolutionary conserved homologues among a broad range of flowering plants, the possibility of generating nodular symbioses in non‐legumes via a limited number of genetic modifications is being considered (Markmann & Parniske, 2009).…”

Multicomponent symbiosis of legumes with beneficial soil microorganisms: Genetic and evolutionary bases of application in sustainable crop production

“…The tech nology of its production was developed by the group of co authors of this paper (Chebotar' et al, 2008); b) the creation of a breeding nursery with soil that was enriched in BSM in order to select plants with high symbiotic effectiveness; c) the development of breeding protocol for legumes which is aimed at increase of the effectiveness of interactions with BSM; d) the on purpose creation of history's first "Tri umph" pea variety, which is characterized by an RUSSIAN increased potential of interaction with BSM as com pared to other cultivars (as a result of competitive vari ety tests, Orel, 2004Orel, -2006. This variety increases productivity by 10-15% upon inoculation with a com plex microbial fertilizer without any dependence on changing climatic conditions (Shtark et al, 2006;Borisov et al, 2008). The "Triumph" variety, which is characterized by high productivity also under condi tions of traditional tillage technology, is recom mended, according to the results of the state variety test (2007)(2008), for tillage in the Central Region of the Russian Federation.…”
