Scientists produce faster-growing crops

Scientists have improved "the most important biological process on the planet" - photosynthesis.

The breakthrough, published in the journal Science, external, used genetic modification to increase the amount of sunlight energy crop plants can channel into food production.

That increased yield in an experimental crop by 15%.

Researchers say this is a critical step towards increasing crop production to feed a growing global population.

BBC science reporter Victoria Gill explains the findings.
