Making Rhizobium-Infected Root Nodules

2008
Rhizobium bacteria have the unique capability to establish a symbiosis with higher plants of the taxonomic family of Fabaceae (also named Leguminosae) in which a new root organ, the nodule, is formed. In this nodule atmospheric nitrogen (N2) is fixed into ammonia and supplied to the plant. It is this symbiosis that will be central in this chapter.

Root-nodule Bacteria

2001
Probably the most astonishing aspect of the root-nodule bacteria (hereafter rhizobia) of the Mediterranean basin is how little we actually know about them! Given their relative importance to agriculture in that region, as well as in other world regions that share a similar climate, it is surprising that so few comprehensive studies of the ecology of ...

Molecular Mechanisms in Root Nodule Development

Journal of Plant Growth Regulation, 2000
Under nitrogen-limiting conditions, bacteria from the family Rhizobiaceae establish a symbiosis with leguminous plants to form nitrogen-fixing root nodules. These organs require a coordinated control of the spatiotemporal expression of plant and bacterial genes during morphogenesis.

Peroxidase content of soybean root nodules

Biochimica et Biophysica Acta (BBA) - Enzymology, 1980
A peroxidase has been isolated from soybean nodules and its main characteristics have been determined. Its molecular weight (48 000) and spectral properties are similar to those of usual plant peroxidases. Its activity is comparable to that of low-efficiency plant peroxidases. The rate constant of the reaction with H2O2 is 3 x 10(5) M-1 x s-1.

Root Nodules of Podocarpus

Ecology, 1932
Recently Saxton ('30) in a interesting paper outlined the principal features of an investigation into the organisms present in the root nodules of Podocarpus latifolius R. Br. (P. Thunbergii Hook).' It seems that absence of bacteria and the presence of endotrophic fungal hyphae, or mycorhiza, were established from investigation of histological ...

REGULATION OF SYMBIOTIC ROOT NODULE DEVELOPMENT

Annual Review of Genetics, 1998
▪ Abstract  Symbiosis between rhizobia and leguminous plants leads to the formation of N2-fixing root nodules. The interaction of rhizobia and plants shows a high degree of host specificity based on the exchange of chemical signals between the symbiotic partners.

Hydrogenase in pea root nodule bacteriods

Archiv f�r Mikrobiologie, 1968
Hydrogen uptake has been shown to occur with pea root nodule breis and this uptake has been shown to be confined to the bacteriods. The uptake of hydrogen by washed bacteriods, in the absence of any added substrates, has been shown to be accompanied by oxygen uptake and the ratio of hydrogen uptake to oxygen uptake in these preparations has been found ...

Dehydrogenase Isoenzymes from Legume Root Nodules

Nature, 1966
ALTHOUGH dehydrogenase isoenzymes, especially lactate dehydrogenases, have been extensively studied in vertebrate tissues1–4, there is little information available about molecular heterogeneity among plant dehydrogenases. During enzymological studies of root nodules from three different legume species, multiple forms of lactate dehydrogenase (L-lactate

Legume and actinorhizal root nodule formation

1997
Root nodule symbiosis is the result of the interaction of bacteria and higher plants. This interaction leads to the formation of root nodules the organ in which the bacteria are able to reduce atmospheric nitrogen. Two different nodule symbioses occur: 1. Actinorhizal symbiosis that is established between Frankia, gram-positive soil bacteria, and plant

Bacterial Root Nodules in the Zygophyllaceæ

Nature, 1946
IN addition to the legumes, a number of non-legumes are reported to possess nodules on their roots. Some of these nodules are caused by bacteria while others are caused by Actinomyces. It may be interesting to mention that bacterial nodules are also found on the roots of the Zygophyllaceae.
