Description: 隨著世界人口成長及日益明顯的氣候變遷效應，我們必須以愈來愈少的可耕作土地餵飽愈來愈多的人。分子生物學家吉兒‧法倫特研究一種非常罕見的現象，可能有所助益：「復甦植物。」這是一種超耐旱植物，可以自己起死回生。這種植物可否為愈來愈乾熱的世界帶來一線希望？

我們如何讓作物在無水狀態下存活

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.
