Desiccation tolerance evolved multiple times across the land plants for survival in water-limited habitats. We find that desiccation tolerance evolved convergently in grasses by independent duplication of the same gene family and activation of conserved, ancestral protective pathways.

复活草的比较揭示了耐旱性的趋同进化


为了在水资源有限的栖息地中生存，陆地植物的耐干燥能力经历了多次进化。我们发现，通过相同基因家族的独立复制和保守的祖先保护途径的激活，禾本科植物的耐干燥性会趋同进化。
