Methods for improving corn yield

TL;DR: The hypothesis that the herbicide glyphosate acts on plants and microorganisms by inhibiting synthesis of 5-enolpyruvyl-3-phosphoshikimate, a precursor to aromatic amino acids, was tested and a mutation confers high resistance to glyphosate when introduced in Escherichia coli in the presence or absence of the wild-type aroA allele.

TL;DR: Four Methylobacterium extorquens strains were isolated from strawberry leaves, and one strain, called ME4, was tested for its ability to promote the growth of various plant seedlings, suggesting the production of a growth-promoting agent by the methylotroph.

TL;DR: There is a strong selection pressure at the species level of Methylobacterium residing on a given plant species, and that selection of appropriate species that can persist on the plant is important to achieve growth promotion.

TL;DR: In this article, an artificially manufactured formula containing a nitrogen-fixing bacterium that efficiently colonizes non-legume plants in aerial parts and the root system was proposed to reduce chemical fertilizer usage and greenhouse gas nitrous oxide emission.
