Scientists ID bacterial genes that improve plant growth
Date:5/13/2010

ebastien Monchy, and metabolic analyses performed at the University of South Carolina in collaboration with Brookhaven plant scientist Lee Newman the scientists identified an extended set of genes that help Enterobacter (sp. 638) establish itself in this niche. The studies also revealed remarkable interactions between the microbe and its host that help the plant survive and thrive.

Among the bacterial genes identified are ones that code for proteins that: help the microbe survive and compete with other species for resources in the soil; take up nutrients released by plant roots; and move toward, adhere to, and colonize poplar root tissues. The microbes also have genes that provide benefits for the plant, including: genes that may help confer drought resistance and the ability to coexist with toxic metals; genes that produce antimicrobial agents that protect plants from fungal and bacterial infections; and genes that produce plant-growth enhancing "phytohormones" and precursors that poplar cannot produce on its own.

"One of the most remarkable things about this association, which we confirmed with our metabolic assays, is that the production of these plant-growth-promoting phytohormones is directly dependent on the presence of plant-synthesized sugars, such as sucrose, in the growth medium. In addition, one metabolite (meso-2,3 butanediol) is known to elicit the induction of systemic tolerance to drought and induced systemic resistance against plant diseases," Taghavi said. So the plant makes sugar that helps the bacteria grow and make phytohormones and other compounds that help the plants grow better and healthier.

"Interestingly, the genes that allow the bacteria to metabolize sucrose and the genes that produce the phytohormones are located on a genomic island, suggesting they may have been acquired together via natural horizontal gene transfer," Taghavi said.

The scientists plan to continue their work by studying how these vari
