The grass subfamily Pooideae: Cretaceous–Palaeocene origin and climate‐driven Cenozoic diversification
Aim Frost is among the most dramatic stresses a plant can experience, and complex physiological adaptations are needed to endure long periods of sub‐zero temperatures. Owing to the need to evolve these complex adaptations, transitioning from tropical to temperate climates is regarded as difficult. H...
