Sweet way to greater yields

Three years ago, biotechnologists demonstrated in field trials that they could increase the productivity of maize by introducing a rice gene into the plant that regulated the accumulation of sucrose in kernels and led to more kernels per maize plant.

They knew that the rice gene affected the performance of a natural chemical in maize, trehalose 6-phosphate (T6P), which influences the distribution of sucrose in the plant. But they were keen to discover more intimate details of the relationships governing the increased productivity.

“Now we know far more about how this yield effect has been achieved,” says Matthew Paul, who led the Anglo-American team from Rothamsted Research and Syngenta, a biotechnology company that also funded the work. The team’s findings are published today in Plant Physiology.
