Transition metal transporters in rhizobia: Tuning the inorganic micronutrient requirements to different living styles
(Royal Society of Chemistry, 2019-04)
A group of bacteria known as rhizobia are key players in symbiotic nitrogen fixation (SNF) in partnership with legumes. After a molecular exchange, the bacteria end surrounded by a plant membrane forming symbiosomes, ...
A stringent response-defective Bradyrhizobium diazoefficiens does not activate the type-3-secretion system, elicits early plant defense, and circumvents NH 4 NO 3 -induced inhibition of nodulation
(American Society for Microbiology, 2021-04-13)
When subjected to nutritional stress, bacteria modify their amino acid metabolism and cell division activities by means of the stringent response, which is controlled by the Rsh protein in alphaproteobacteria. An important ...
Comparative phylogenetic and expression analysis of small GTPases families in legume and non-legume plants
(Taylor and Francis Incs, 2018-02)
Background: Small monomeric GTPases act as molecular switches in several processes that involve polar cell growth, participating mainly in vesicle trafficking and cytoskeleton rearrangements. This gene superfamily has ...
A phylogenetically conserved group of NF-Y transcription factors interact to control nodulation in legumes
(American Society of Plant Biologist, 2015-10)
The endosymbiotic association between legumes and rhizobia leads to the formation of root nodules in which differentiated bacteria convert atmospheric nitrogen into a form that can be assimilated by the host plant. Successful ...
A review: Quorum sensing in Bradyrhizobium
(Elsevier Science, 2015-05)
Quorum sensing (QS) systems are an important form of cellular communication in bacteria. QS systems are based on the synthesis and secretion of a chemical signal (autoinducer) that accumulates as a function of population ...
