Stress on plants imposed by flooding of the soil and deeper submergence constitutes one of the major abiotic constraints on growth, species' distribution and agricultural productivity. Flooding stress is also a strong driver of adaptive evolution. This has resulted in a wide range of biochemical, molecular and morphological adaptations that sanction growth and reproductive success under episodic or permanently flooded conditions that are highly damaging to the majority of plant species. However, even seemingly poorly adapted species possess some short-term resilience that is important for overall success of these plants in various habitats. The papers contained in this Special Issue address these topics and emphasize molecular, biochemical and developmental processes that impact on flooding tolerance. Most of the articles are based on lectures given to the 8th Conference of the International Society for Plant Anaerobiosis (ISPA), held at the University of Western Australia, Perth, 20-24 September, 2004. Reviews and research papers are presented from the leading laboratories currently working on plant responses to flooding stress.
土壤淹水和深度浸没对植物造成的胁迫是生长、物种分布和农业生产力的主要非生物限制因素之一。淹水胁迫也是适应性进化的强大驱动力。这导致了广泛的生化、分子和形态学适应，使得植物在对大多数植物物种具有高度破坏性的间歇性或永久性淹水条件下仍能实现生长和繁殖成功。然而，即使是看似适应性较差的物种也具有一定的短期恢复力，这对这些植物在各种生境中的整体成功至关重要。本期特刊中的论文探讨了这些主题，并强调了影响耐淹性的分子、生化和发育过程。大多数文章基于在2004年9月20日至24日于珀斯的西澳大利亚大学举行的第8届国际植物厌氧生物学协会（ISPA）会议上的讲座。来自目前致力于研究植物对淹水胁迫反应的顶尖实验室的综述和研究论文被呈现出来。
