Bradyrhizobium
Rhizobiaceae
Symbiosis
Nitrogen Fixation
Soybeans
Root Nodules, Plant
Knobbed structures formed from and attached to plant roots, especially of LEGUMES, which result from symbiotic infection by nitrogen fixing bacteria such as RHIZOBIUM or FRANKIA. Root nodules are structures related to MYCORRHIZAE formed by symbiotic associations with fungi.
Plant Root Nodulation
The formation of a nitrogen-fixing cell mass on PLANT ROOTS following symbiotic infection by nitrogen-fixing bacteria such as RHIZOBIUM or FRANKIA.
Fabaceae
The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.
Rhizobium
A genus of gram-negative, aerobic, rod-shaped bacteria that activate PLANT ROOT NODULATION in leguminous plants. Members of this genus are nitrogen-fixing and common soil inhabitants.
Acacia
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Plant Roots
Lespedeza
A plant genus of the family FABACEAE.
Pachyrhizus
A plant genus of the family FABACEAE. Some Pachyrhizus have been reclassified to PUERARIA. Do not confuse with yam (IPOMOEA; or DIOSCOREA) or African yam bean (SPHENOSTYLIS).

Afipia
A genus of gram-negative, oxidase-positive, nonfermentative rods which are motile by means of a single flagellum. Afipia felis and BARTONELLA HENSELAE are causative agents of CAT-SCRATCH DISEASE. (From Bergey's Manual of Determinative Bacteriology, 9th ed)

Lupinus
A plant genus of the family FABACEAE that is a source of SPARTEINE, lupanine and other lupin alkaloids.
2,4-Dichlorophenoxyacetic Acid
Alphaproteobacteria
Cytisus
A plant genus of the family FABACEAE that is sometimes called broom because of the shape of the plant. Members produce SPARTEINE.
Rhodobacter
Hemeproteins

Canthaxanthin
A trans-carotenoid pigment widely distributed in nature. The compound is used as an oral suntanning agent and as a food and drug coloring agent. Oral ingestion of the compound causes canthaxanthin retinopathy.
Oxidoreductases
The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9)
