Resurrection plants can tolerate extreme water loss. Substantial sugar accumulation is a phenomenon in resurrection plants during dehydration. Sugars have been identified as one important factor contributing to desiccation tolerance. Phylogenetic diversity of resurrection plants reflects the diversity of sugar metabolism in response to dehydration. Sugars, which accumulate during dehydration, have been shown to protect macromolecules and membranes and to scavenge reactive oxygen species. This review focuses on the performance of enzymes participating in sugar metabolism during dehydration stress. The relation between sugar metabolism and other biochemical activities is discussed and open questions as well as potential experimental approaches are proposed.
复苏植物能够耐受极端的水分流失。大量糖分积累是复苏植物在脱水过程中出现的一种现象。糖类已被确认为有助于耐脱水能力的一个重要因素。复苏植物的系统发育多样性反映了其在脱水响应中糖代谢的多样性。在脱水过程中积累的糖类已被证明能够保护大分子和膜结构，并清除活性氧。本综述聚焦于脱水胁迫期间参与糖代谢的酶的表现。讨论了糖代谢与其他生化活动之间的关系，并提出了未解决的问题以及潜在的实验方法。
