Leguminous Plants: Inventors of Root Nodules to Accommodate Symbiotic Bacteria
2015Legumes 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, 1966As 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, 1989Split‐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, 2002A 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, 1947IT 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, 1956By 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.

Root Nodule Development in Model Versus Non-canonical Plants
2019Nitrogen-fixing symbiosis is the most successful metabolism-dependent mutualistic symbiosis on earth that influences global nitrogen cycles. Engineering and improvement of this symbiosis is the major avenue towards sustainable agriculture. Root nodule symbiosis (RNS) is restricted to a monophyletic group of angiosperm order.

Expression of plant genes during the development of pea root nodules
The EMBO Journal, 1985The expression of plant genes involved in the pea-Rhizobium symbiosis was studied by analysing mRNA from root nodules. The RNA was translated in vitro and the translation products were separated by two-dimensional gel electrophoresis. The results show differential expression of nodulin genes during root nodule development.

Peroxidase Isozymes in Root Nodules of Various Leguminous Plants
Nature, 1963MULTIPLE forms of various enzymes (isozymes) have been shown in tissues of animals1–3 and plants4,5 and in micro-organisms6. The difference in electrophoretic mobility of some isozymes obtained from different species has been reported4,5,7. This communication reports the existence of peroxidase isozymes which differ electrophoretically in root nodules ...
