Perennial forage grasses are major species for agriculture and food security. Production of grasses is threatened by increasing drought periods in the context of climate change. Norton et al. review the knowledge of factors influencing plant drought survival. They propose solutions such as increasing the depth and density of grass root systems to strengthen dehydration avoidance, and identifying non-toxic endophyte strains compatible with summer-dormant cultivars of tall fescue to enhance drought survival.
