They threaded seagrass leaves through a little hole in a latex glove and placed the plants roots in a bottle, sealing the glove over the rim. A day or two later on, Mohr and her team dissected the plants and measured how much of the nitrogen tracer had been fixed within the roots. “This is an amazing system that they made,” states University of California, Davis, seagrass microbiome scientist Jonathan Eisen.In plants gathered throughout their summer season growing season, Mohrs group saw recently fixed nitrogen in the roots and found that a fifth of it moved to the leaves within 24 hours. When they evaluated plants collected in non-summer months, lower levels of recently repaired nitrogen in the roots likewise associated with lower levels of this microbe. C. neptuna genes for nitrogenase, the enzyme that facilitates the fixation procedure, were heavily transcribed when nitrogen was being fixed, and that the nitrogen tracer became integrated into the germss amino acids.
