Chinese scientists rush to climate-proof potatoes

In a research facility in the northwest of Beijing, molecular biologist Li Jieping and his team harvest a cluster of seven unusually small potatoes, one as tiny as a quail’s egg, from a potted plant.
Grown under conditions that simulate predictions of higher temperatures at the end of the century, the potatoes provide an ominous sign of future food security.
At just 136gm (4.8 oz), the tubers weigh less than half that of a typical potato in China, where the most popular varieties are often twice the size of a baseball.
China is the world’s biggest producer of potatoes, which are crucial to global food security because of their high yield relative to other staple crops.
But they are particularly vulnerable to heat, and climate change is pushing temperatures to dangerous new heights while also worsening drought and flooding.
