According to Bailey, this approach can also be used to target genomes
of endophytes (i.e., fungi that live in plants) and prokaryotic parasites in plant DNA samples.
They took leaves from a closely related wild that plant was healthy and contained a typical mix
of endophytes, blended them into a smoothie and sprayed the mixture onto the leaves of P. kaalaensis to see if beneficial microbes could be transplanted from one species to another.
By isolating five bacterial strains
of endophytes found inside S. halepense rhizomes (subterranean stems used for storage and vegetative reproduction) and growing them in the lab in different mixtures of substrates, the authors determined that these microbes were able to fix and mobilize nitrogen, phosphorus, and iron.
I did my research in the lab of Bud Stamen, on the effect
of endophytes on plant stress.
Research at STRI has also shown that, as with humans, microbes stimulate plants» ability to defend themselves and has demonstrated the magnitude and extent
of endophyte effects on host genetic expression.

Subsequent literature searches led to the discovery that sugar cane, an agriculturally important crop, is a nitrogen fixer that contains bacterial
endophytes, and Rout became curious if the microbes she and her colleague Tom Chrzanowski (The University
of Texas Arlington) discovered in invasive Sorghum might be providing similar benefits to this invasive plant.

of the Helotiales thrive in various ecosystems and cover a broad range
of niches, and helotialean fungi have been described as plant pathogens,
endophytes, mycorrhizae, fungal parasites, terrestrial saprobes, aquatic saprobes, root symbionts, and wood rot fungi.
