Arbuscular mycorrhiza (AM), a symbiosis between plants and members of an ancient
phylum of fungi, the Glomeromycota, improves the supply of water and nutrients, such as …

Members of the rhizobia are distinguished for their ability to establish a nitrogen-fixing
symbiosis with leguminous plants. While many details of this relationship remain a mystery …

Most higher plant species can enter a root symbiosis with arbuscular mycorrhizal fungi, in
which plant carbon is traded for fungal phosphate,. This is an ancient symbiosis, which has …

Leguminous plants are able to establish a nitrogen-fixing symbiosis with soil bacteria
generally known as rhizobia. Metabolites exuded by the plant root activate the production of …

Several genes have recently been identified using legume mutants that are defective for
nodulation signalling. The proteins they encode include novel types of receptor-like kinase …

Plant roots form intracellular symbioses with fungi and bacteria resulting in arbuscular
mycorrhiza and nitrogen-fixing root nodules, respectively. A novel receptor like-kinase has …

A combined genetic and transcriptome analysis was performed to study the molecular basis
of the arbuscular mycorrhiza (AM) symbiosis. By testing the AM phenotype of nodulation …

Biological nitrogen fixation is a process that can only be performed by certain prokaryotes. In
some cases, such bacteria are able to fix nitrogen in a symbiotic relationship with plants …

Retrotransposons are mobile genetic elements that accomplish transposition via an RNA
intermediate that is reverse transcribed before integration into a new location within the host …

Changes in intracellular calcium in pea root hairs responding to Rhizobium leguminosarum
bv. viciae nodulation (Nod) factors were analyzed by using a microinjected calcium-sensitive …
