Symbiotic association between Atriplex aff. cordobensis Gand et Stukert (Cariofilales) and Frankia sp. (Actinomycetales)
Among the symbiont diazotroph microorganisms in non-leguminous plants, the genus Frankia (Actinomycetales) is mentioned. A. aff. cordobensis (Caryophyllales) is a forage shrub which grows in soils with high alkalinity (pH: 8.5-9). In this paper we intend to prove the Atriplex-Frankia symbiotic relat...

| Sumario: | Among the symbiont diazotroph microorganisms in non-leguminous plants, the genus Frankia (Actinomycetales) is mentioned. A. aff. cordobensis (Caryophyllales) is a forage shrub which grows in soils with high alkalinity (pH: 8.5-9). In this paper we intend to prove the Atriplex-Frankia symbiotic relationship, to verify the presence of Actinomycetes in soils and to isolate the endophyte in an artificial QMOD medium. The Atriplex-Frankia symbiosis has been really proved. Besides, the plants growing in their native soil modulated regularly. This fact shows that, undoubtedly, the genus Frankia inhabits the studied soils of arid regions. The strains isolated from A. aff. cordobensis grew in the complex QMOD medium and showed the typical morphological characteristics of Actinomycetes. |
