San Diego: Scientists
have shown that certain proteins in plants that function as
transporters can help solve global fuel and food problems, a study
says.
New discoveries of the way plants transport important substances
across their biological membranes to resist toxic metals and
pests, increase salt and drought tolerance, control water loss and
store sugar can have profound implications for increasing the
supply of food and energy for our rapidly growing global
population.
That is the conclusion of 12 leading plant biologists from around
the world, whose laboratories recently discovered important
properties of plant transport proteins that, collectively, can
have a profound impact on global agriculture, reports Science
Daily.
They report in the May 2 issue of the journal Nature that their
findings can help the world meet its increasing demand for food
and fuel as the global population grows from seven billion people
to an estimated nine billion by 2050.
"These membrane transporters are a class of specialised proteins
that plants use to take up nutrients from the soil, transport
sugar and resist toxic substances like salt and aluminum," said
Julian Schroeder, a professor of biology at UC San Diego.
Schroeder brought together 11 other scientists from Australia,
Japan, Mexico, Taiwan, the US and Britain to collaborate on a
paper describing how their discoveries collectively could be used
to enhance sustainable food and fuel production.
