Seedlings of Hippophaë rhamnoides possessing two equally infectible root systems (‘split roots’) were used in conjunction with specific Frankia strains to investigate plant control over nodulation. When a wild-type Frankia strain was inoculated onto both root systems simultaneously or 1, 2, 4, or 8 weeks apart, an inhibitory response occurred which retarded nodulation on the root exposed to the delayed inoculum. Similar suppressive responses were also observed when two different wild-type… 

Induction of Actinorhizal Nodules by Frankia

An overview of infection mechanisms and nodule structure is given; comparisons with the corresponding mechanisms in legume–rhizobia symbioses are presented.

Feedback regulation of nodule formation in alfalfa

Alfalfa has an active, systemic mechanism for feedback control of nodulation and elicitation of the regulatory response need not be proportional to nodule formation, which implies that genes in region IIa play an important role in elicitation.

Evidence that associated soil bacteria may influence root hair infection of actinorhizal plants by Frankia.

It is proposed that the bacterial isolates aid in the infection process at the host root hair surface, by causing root hair deformation; this may allow intimate contact between the Frankia filament and the hair wall.

Suppression of nodule development of one side of a split-root system of soybeans caused by prior inoculation of the other side.

In a split-root system of soybeans (Glycine max L. Merr), inoculation of one half-side suppressed subsequent development of nodules on the opposite side, and nodule suppression was significantly more pronounced in the shaded treatments.

Lack of Systemic Suppression of Nodulation in Split Root Systems of Supernodulating Soybean (Glycine max [L.] Merr.) Mutants.

Observations indicate that autoregulation deficiencies in mutant nts382 result in a reduction of systemic suppression of nodulation, some suppression is detectable after 24 hours with a delayed inoculation, and soybean genotypes differ in their ability to express this systemic suppression.

Genetic heterogeneity among Frankia isolates from root nodules of individual actinorhizal plants

Genetic variations among selected Frankia isolates from nitrogen-fixing root nodules harvested from an individual actinorhizal plant were estimated by restriction fragment analysis of their total genomic DNA.

Split-Root Assays Using Trifolium subterraneum Show that Rhizobium Infection Induces a Systemic Response That Can Inhibit Nodulation of Another Invasive Rhizobium Strain

The mutants were affected in their competitive ability, and this finding was reflected by poor nodule occupancy when the mutants were coinoculated with the parent strain onto a single root system.
