Leguminous plant roots can form a symbiosis with soil-dwelling nitrogen-fixing rhizobia,
leading to the formation of a new root organ, the nodule. Successful nodulation requires co …

The symbiotic infection of root cells by nitrogen-fixing rhizobia during nodulation requires the
transcription factor Nodule Inception (NIN). Our root hair transcriptomic study extends NIN's …

Regions of the Rhizobium meliloti symbiotic plasmid (20 to 40 kilobase pairs long)
containing nodulation (nod) genes were transferred to Agrobacterium tumefaciens or …

Rhizobial bacteria enter a symbiotic association with leguminous plants, resulting in
differentiated bacteria enclosed in intracellular compartments called symbiosomes within …

Under nitrogen-limiting conditions Rhizobium meliloti can establish symbiosis with
Medicago plants to form nitrogen-fixing root nodules. Nodule organogenesis starts with the …

The Sym plasmid pRL1JI encodes functions for the formation of nitrogen-fixing pea root
nodules by Rhizobium leguminosarum. Some of the nodulation genes are involved in …

We examined the timing and location of several early root responses to Rhizobium
leguminosarum bv. trifolii infection, compared with a localized addition of cytokinin in white …

The objectives of this review are to compare and to contrast Rhizobium and plant pathogens
in binding to host plant cells, to describe how rhizobia penetrate host plant cells and how the …

To help dissect the molecular basis of the Rhizobium-legume symbiosis, we used in vitro
translation and Northern blot analysis of nodule RNA to examine alfalfa-specific genes …

Current evidence suggests that legumes evolved about 60 million years ago. Genetic
material for nodulation was recruited from existing DNA, often following gene duplication …
