Metabolomic effects of the colonization of Medicago truncatula by the facultative endophyte Arthrobacter agilis UMCV2 in a foliar inoculation system.

Biofertilizer production and application for sustainable agriculture is already a reality. The methods for biofertilizers delivery in crop fields are diverse. Although foliar spray is gaining wide acceptance, little is known about the influence that the biochemical features of leaves have on the microbial colonization.

A Mass Spectrometry-Based Study Shows that Volatiles Emitted by UMCV2 Increase the Content of Brassinosteroids in in Response to Iron Deficiency Stress.

Iron is an essential plant micronutrient. It is a component of numerous proteins and participates in cell redox reactions; iron deficiency results in a reduction in nutritional quality and crop yields. Volatiles from the rhizobacterium UMCV2 induce iron acquisition mechanisms in plants.

Purification and characterization of a calcium-dependent protein kinase from beetroot plasma membranes.

Several calcium-dependent protein kinases (CDPKs) are located in plant plasma membranes where they phosphorylate enzymes and transporters, like the H(+)-ATPase and water channels, thereby regulating their activities. In order to determine which kinases phosphorylate the H(+)-ATPase, a calcium-dependent kinase was purified from beetroot (Beta vulgaris L.) plasma membranes by anion-exchange chromatography, centrifugation in glycerol gradients and hydrophobic interaction chromatography.
