Scientists find a way to develop crops that can withstand eco-stress

An international team of researchers has uncovered a genetic secret within barley seeds that could help protect the global food supply from the unpredictable effects of climate change. The study, published on Nov 6 in the journal Science, identifies a specific biological "timer" that controls when a seed decides to "wake up" and grow.

The research involved scientists from top institutes in China, Denmark, France, and the United Kingdom. Their focus was on a trait called seed dormancy, which is essentially a natural state of sleep that prevents seeds from sprouting even when environmental conditions appear favorable. While this helps plants survive in the wild, it creates what lead researcher Wang Yucheng calls a "double-edged sword" for modern agriculture.

Wang, a professor at the Institute of Tibetan Plateau Research of the Chinese Academy of Sciences, explained that if seeds wake up too early, they might sprout while still attached to the plant before harvest. This issue, known as preharvest sprouting, ruins the quality of the grain and leads to more than $1 billion in losses annually. Conversely, if the seeds stay asleep too long, they will not grow in time for the next planting season, throwing the entire farming schedule off.
