Climate change affects the agricultural sector by modifying precipitation patterns, increasing extreme weather events, and geographically shifting agriculturally viable areas. These climate alterations substantially impact plant resilience to abiotic stress and, consequently, agricultural productivity. A better understanding of plant adaptations to tolerate extreme environmental conditions could pave the way for future advances in agricultural sustainability. One such adaptation is vegetative desiccation tolerance (VDT), which enables some species, known as 'resurrection plants', to undergo almost complete drying without losing viability. The current review discusses how incorporating different molecular and biochemical mechanisms underlying VDT into crops might expand the time during which crops can continue growing under limiting water conditions and perhaps broaden the range of survivable negative water potentials that a crop can endure under drought stress. Such possibilities could alleviate the detrimental consequences of low water availability to crops. Understanding how plants survive extreme dehydration has the potential to enlighten new strategies to improve the climate resiliency of crops, thereby positively impacting worldwide food security and sustainability.This article is part of the theme issue 'Crops under stress: can we mitigate the impacts of climate change on agriculture and launch the 'Resilience Revolution'?'.
气候变化通过改变降水模式、增加极端天气事件以及在地理上转移农业可种植区域来影响农业部门。这些气候改变极大地影响了植物对非生物胁迫的恢复力，进而影响农业生产力。更好地理解植物适应极端环境条件的机制可为未来农业可持续发展的进步铺平道路。一种这样的适应能力是营养体耐旱性（VDT），它使一些被称为“复苏植物”的物种能够在几乎完全干燥的情况下仍不丧失活力。本综述讨论了将VDT背后不同的分子和生化机制引入作物中，如何可能延长作物在水分有限条件下能够继续生长的时间，并且或许扩大作物在干旱胁迫下能够承受的可存活负水势范围。这些可能性能够减轻水分供应不足对作物造成的有害后果。了解植物如何在极端脱水条件下存活，有可能启发新的策略来提高作物的气候恢复力，从而对全球粮食安全和可持续性产生积极影响。本文是主题为“受胁迫的作物：我们能否减轻气候变化对农业的影响并发起‘恢复力革命’？”这一特刊的一部分。
