Swiss uncover fungus that speeds up rice growth
Researchers at a Swiss university said Thursday that they have
uncovered a microscopic fungus that is able to increase the speed of
rice growth by five times.
In a study published by Switzerland’s University of Lausanne,
researchers claimed that the fungus mycorrhiza would not only cut the
use of phosphate fertilizers, it was also “completely natural” or
GM-free.
It could be commercialised and used in large-scale farming in two to
five years, said the researchers.
The team uncovered the function of the super fungus after four years
of experiments on twenty different samples of its spores.
Results showed however that while some of these spores led to slower
growth of rice, in two of the samples, rice growth was accelerated by
five times.
Caroline Angelard, who is among researchers said that the mycorrhiza
was particular as it produced spores that were genetically different.
Depending on their genetic makeup, these spores in turn had a
different impact on rice growth.
However, the researcher added that it was still unclear how the
spores helped to speed up rice growth.
“We still have to study how this symbiosis between the fungus and the
rice plant led in some conditions to the accelerated growth of the rice
plant,” Angelard told AFP.
Ian Sanders, who led the research, pointed out that the advantage of
using the fungus to boost rice growth was that it is “completely
natural.”
“No new gene had been introduced in the plant and it has nothing to
do with genetically modifying the plant,” he said in a statement.
The fungus almost invisible to the naked eye also has another
advantage for cultivators as threadlike elements called hypha allow for
a symbiosis with the rice plant, ensuring the transportation of
nutrients and minerals like phosphates.
It could therefore help to cut the usage of phosphate fertilizers and
therefore reduce the ecological footprint of agriculture.
The researchers have also undertaken studies on potatoes in Colombia,
and experiments are expected in 2011 on tapioca.
