But in the wake
of recent and unexpected discoveries suggesting that cereals already have the biological machinery to accommodate
rhizobia, researchers are keen to give it another shot (see «Evolutionary push could help crops self - fertilise»).
The good news is that beans, peas and other legumes can already pluck nitrogen from air with the help
of soil bacteria called
rhizobia.
Three options are on the table: tweak cereals so that they form symbiotic partnerships with
rhizobia as legumes do; colonise cereal roots with other types
of nitrogen - fixing bacteria; or transfer the bacterial genes that make fertiliser directly into the crop plants.
Ober: «Just last month the
rhizobia were awarded «Microbe
of the Year 2015» because
of their growth - promoting properties by the Association for General and Applied Microbiology (VAAM).
During the further course
of the study the researchers «infected» the plants with the same
rhizobia that occur in the Crotalaria's area
of spread.
Rhizobia - hosting plants, mostly in the legume family, recruit
rhizobia from the soil to infect their roots, forming specialized nodules
of root tissue to house the bacteria and provide them with sugars as a food resource.
Research into the legume -
rhizobia relationship will lead to improved yield, elimination
of a major fertilizer input, and improved designs for sustainable agriculture.
In a complicated exchange
of nutrients,
rhizobia produce an abundance
of nitrogen, making it available to the plant.
Like other members
of the legume family, tamarind roots have a symbiotic relationship with
rhizobia, beneficial bacteria that fix nitrogen in the soil.
