如何让植物在无水状态下存活

随着世界人口的增长和愈加明显的环境改变我们必须用更少的土地养育更多的人。分子生物学家吉尔·法兰特通过研究一种稀有的现象“复苏植物”希望对此有所帮助。复苏植物就是具有超强抵抗干旱能力似乎可以死而复生的植物。它们会带来将来在更加燥热干旱的土地上种植粮食的希望么？

Resurrection plants can survive losing up to 95 percent of their water and spring back to life within days when rehydrated. As the world faces growing food demands and shrinking arable land due to climate change, these rare plants offer a blueprint for engineering crops that can survive extreme drought. By unlocking how these plants switch on survival genes, scientists hope to help staple foods like maize and rice thrive in harsher climates. This approach could transform food security for billions as rainfall patterns shift.
