Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual
