EXCERPTS: The obliging microbe, a type of bacteria called Pseudomonas, was identified lurking around the roots of plants exposed to high salt levels, a situation expected to grow worse as climate change causes rising sea levels that push salty water further inland from the coast.
Researchers on a new Science Advances paper observed that while other bacterial colonies died off under salty conditions, Pseudomonas microbes continued to thrive around the roots of wild soybean plants. They think this is because the bacteria contain specialized genes, and it suggests that the microbes hold a competitive advantage under salty conditions.
[...] They found that not only did the bacteria swiftly colonize soybean roots—their numbers rising twofold under salt stress—but compared to controls the inoculated soybeans also experienced a significant growth boost under salty conditions, developing considerably longer roots and also forming more lateral ones. The soybeans showed increased salt tolerance in greenhouse experiments, and in open field experiments too.
The question is how the microscopic soil residents seemed to be facilitating this remarkable resilience in plants, something the researchers still don’t have a full answer to. But further investigation gave them some clues—particularly as they noticed that lignin levels in the cell walls of inoculated soybeans increased by between 30 and 35% under salt stress, compared to non-inoculated plants...
