(Reuters) - Plants do complex arithmetic calculations to make sure they have enough food to get them through the night, new research published in journal eLife shows.

(路透社)—刊载于journal eLife 杂志上的新研究结果显示,植物会做复杂的数学计算确保足够的食物储备安度漫漫长夜。

Scientists at Britain's John Innes Centre said plants adjust their rate of starch consumption to prevent starvation during the night when they are unable to feed themselves with energy from the sun.

英国约翰英纳斯中心的科学家说,植物会调整淀粉消耗率以防夜里挨饿。在夜间它们无法通过光合作用摄入能量。

They can even compensate for an unexpected early night.

他们甚至可以应对早于预期的入夜。

"This is the first concrete example in a fundamental biological process of such a sophisticated arithmetic calculation," mathematical modeler Martin Howard of John Innes Centre (JIC) said.

英国约翰英纳斯中心的数模师马丁霍华德说:“如此精密的数学运算,是在基础生物学过程上的首个具体案例。”

During the night, mechanisms inside the leaf measure the size of the starch store and estimate the length of time until dawn. Information about time comes from an internal clock, similar to the human body clock.

在夜间,藏在叶子里的机制就在测量淀粉储备的规模并预测到清晨还需的时间。时间的信息来自植物内在的生物钟,就像人体内的生物钟一样。

"The capacity to perform arithmetic calculation is vital for plant growth and productivity," JIC metabolic biologist Alison Smith said.

“美国联合情报中心的代谢生物学家艾莉森史密斯说:“对于植物生长和生产率来说,执行数学运算的能力是至关重要的。”

"Understanding how plants continue to grow in the dark could help unlock new ways to boost crop yield."

他还说,“了解植物是如何在黑暗中继续生长的,有助于发现提高作物产量的新方法。”

2. I sat next to a vegetable in algebra and I can tell you they can’t do math.

我就带着代数知识坐在一颗蔬菜旁边,可以告诉你,它们不会数学。
