Actinorhizal Plant Nodulation and Nitrogen Fixation in Natural and Experimental Systems
In a separate study, water-retentive polymer carriers of Frankia inoculum were applied as a root dip to Alnus glutinosa and Casuarina equisetifoloia seedlings. This treatment increased nodulation 5- to 10-fold in greenhouse experiments and also of A. glutinosa in a field experiment.

Seasonal and site relationships to acetylene reduction by actinorhizal black alder and Russian olive root nodules
Acetylene-reduction activities (ARA) by root nodules of 4- to 8-year-old black alder (Alnus glutinosa (L.) Gaertn.) on an upland Alfisol and alder and Russian olive (Elaeagnus angustifolia L.) on a bottomland Mollisol increased exponentially with soil temperature. Soil moisture content, pH and …

Oxygen control of nitrogen fixation in Frankia and Coriaria arborea
… in both asymbiotic Frankia and Frankia - actinorhizal plant symbioses. Daily addition of fresh medium at a low dilution rate (D=0.125 day⁻¹) allowed Frankia to be maintained in continuous culture with a stable rate of growth and nitrogenase activity for periods of more than 30 days. Use of …

Physiological and nutritional changes in nitrogen fixing trees associated with autumnal senescence and chilling
… Illinois, USA. The dinitrogen fixing species, actinorhizal (Frankia-nodulated) autumn olive and leguminous black locust (Rhizobium-nodulated), resorbed proportionally more net phosphorus (P) than nitrogen (N) from leaves prior to autumnal leaf abscission than the non-fixing species, sycamore …

Rhizobial infection in nodulation
… resembling nodules from the more ancient Frankia-actinorhizal symbiosis. Using kce and other infection mutants I demonstrate that this abnormal nodule architecture results from a failure of infection to reach the nodule cortex. Based on this finding, I predict that Nod factor activated signalling …

Molecular mechanisms of salt and osmotic stress tolerance in Frankia strains isolated from Casuarina trees
… salinity. When in a symbiotic association with actinorhizal plants, Frankia enhances the tolerance of the plants to a range of abiotic stresses, including salinity. The Casuarina-Frankia association has been used to reclaim salt affected soils worldwide. Optimizing the use of the …

Corticular Photosynthetic Dynamics for a Coastal Evergreen Shrub: Myrica Cerifera
I quantified seasonal variations in corticular photosynthesis in 1st through 5th order branches of Myrica cerifera L. (Myricaceae) in order to determine whether corticular photosynthesis contributes to whole plant carbon gain by reducing respirational CO2 loss. Maximum % refixation was 110 ± 39 % …
