Nitrogen Fixation in Non-Legume Root Nodule Plants

Nature, 1957
IT has been shown1–3 that fixation of atmospheric nitrogen is associated with nodule-bearing plants of alder (Alnus glutinosa), bog myrtle (Myrica gale) and sea buckthorn (Hippophae rhamnoides), enabling the plants to grow in a rooting medium free of combined nitrogen just as in the case of legumes. This is well illustrated by Fig.

Nodulation of rooted leaves in leguminous plants

Plant and Soil, 1971
Root formation was obtained on the petioles of detached leaves of several leguminous plants, particularly on the primary leaves of bean. Root formation is easily obtained in artificial light at a temperature of 22 to 24°C. In the greenhouse it is optimal in early spring and late autumn.

Release of mineral nitrogen from plant root nodules

Soil Biology and Biochemistry, 1991
Abstract Root nodules from a variety of nodulated leguminous and non-leguminous plants were added to soil samples and the net release of mineral N was monitored periodically for 56 or 98 days. Over these periods, various nodules demonstrated either net N immobilisation, mineralisation, or immobilisation followed by mineralisation.

Endophyte sporulation in root nodules of actinorhizal plants

Physiologia Plantarum, 1987
All strains of isolated Frankia possess the genetic capacity to form sporangia since, when grown in vitro, they usually sporulate freely, depending on the physical and chemical environment in which they are cultured. Endophytic sporulation involving Frankia differentiation of sporangia within root nodules has been described in only 16 host species in 9

Leguminous Plants: Inventors of Root Nodules to Accommodate Symbiotic Bacteria

2015
Legumes and a few other plant species can establish a symbiotic relationship with nitrogen-fixing rhizobia, which enables them to survive in a nitrogen-deficient environment. During the course of nodulation, infection with rhizobia induces the dedifferentiation of host cells to form primordia of a symbiotic organ, the nodule, which prepares plants to ...

The Cobalt Requirement of Non-legume Root Nodule Plants

Journal of Experimental Botany, 1966
As already shown for Alnus glutinosa, cobalt is found to be essential for the proper growth of nodulated plants of Casuarina cunninghamiana and Myrica gale in a nitrogen-free rooting medium. If cobalt is not supplied, the plants develop symptoms of nitrogen deficiency; under the conditions of the experiments such symptoms became pronounced during the ...

Nitrate Inhibition of Root‐Nodule Symbiosis in Doubly Rooted Soybean Plants

Crop Science, 1989
Split‐root experiments have demonstrated that NO−3 inhibits nodule formation on legumes primarily as a root‐localized effect rather than as a function of whole‐plant N nutrition. The degree to which the root‐localized effect is coupled with the N status of the shoot is not well understood.

Plant growth regulators and phloem exudates modulate root nodulation of soybean

Functional Plant Biology, 2002
A time-course study was conducted on the effect of synthetic ABA and phloem exudate on root nodulation, nitrogenase activity, and dry matter content of pouch-grown soybean [ Glycine max (L.) Merr.]. A hypernodulating mutant (NOD1-3) derived from the cultivar Williams was evaluated. The normally-nodulating cultivar Williams 82 served as the control. All

HÆMOGLOBIN AND NITROGEN FIXATION IN THE ROOT NODULES OF LEGUMINOUS PLANTS

Nature, 1947
IT has been shown by Kubo1 that the root nodules of leguminous plants contain a haemoprotein compound resembling haemoglobin and probably acting as a store as well as a carrier of oxygen. The haematin nature of this pigment was confirmed by Burris and Haas2, who believed, however, that it was not a haemoglobin-like compound which could undergo ...

Some Aspects of Translocation in Root Nodule Plants

Journal of Experimental Botany, 1956
By the use of 15N it is shown that the removal, over a short zone at the base of the shoot of a typical root nodule plant (alder), of the tissues external to the xylem does not interfere with the upward movement of fixed nitrogen from the nodules into the shoot.
