Auxin carriers localization drives auxin accumulation in plant cells infected by Frankia in Casuarina glauca actinorhizal nodules.
Actinorhizal symbioses are mutualistic interactions between plants and the soil bacteria Frankia that lead to the formation of nitrogen-fixing root nodules. Little is known about the signaling mechanisms controlling the different steps of the establishment of the symbiosis. The plant hormone auxin has been suggested to play a role. Here we report that auxin accumulates within Frankia-infected c...
متن کاملAuxin influx activity is associated with Frankia infection during actinorhizal nodule formation in Casuarina glauca.
Plants from the Casuarinaceae family enter symbiosis with the actinomycete Frankia leading to the formation of nitrogen-fixing root nodules. We observed that application of the auxin influx inhibitor 1-naphtoxyacetic acid perturbs actinorhizal nodule formation. This suggests a potential role for auxin influx carriers in the infection process. We therefore isolated and characterized homologs of ...
متن کاملThe isolation of Frankia from nodules of Casuarina
DIEM, H. G., and Y. DOMMERGUES. 1983. The isolation of Frankia from nodules of Casuarina. Can. J. Bot. 61: 2822-2825. Attempting to isolate Frankia from Casuarina, we found that this endophyte exhibited two unexpected characteristics: ( i ) an inability of most infected nodule cells to produce Frankia colonies; and ( i i ) the absence of specific nutritional requirements in the kOht iO! l mCdi?...
متن کاملCharacterization of a Casuarina glauca nodule-specific subtilisin-like protease gene, a homolog of Alnus glutinosa ag12.
In search of plant genes expressed during early interactions between Casuarina glauca and Frankia, we have isolated and characterized a C. glauca gene that has strong homology to subtilisin-like protease gene families of several plants including the actinorhizal nodulin gene ag12 of another actinorhizal plant, Alnus glutinosa. Based on the expression pattern of cg12 in the course of nodule deve...
متن کاملUse of Frankia and Actinorhizal Plants for Degraded Lands Reclamation
Degraded lands are defined by soils that have lost primary productivity due to abiotic or biotic stresses. Among the abiotic stresses, drought, salinity, and heavy metals are the main threats in tropical areas. These stresses affect plant growth and reduce their productivity. Nitrogen-fixing plants such as actinorhizal species that are able to grow in poor and disturbed soils are widely planted...
