| Summary: | Climate change is causing warmer winter and spring periods with increased frequency of chilling and frost damage on crop plants. Psychrotolerant plant-associated bacteria could improve plant tolerance to cold stress. This work aims to identify psychrotolerant bacteria associated with cold-adapted plants and to understand mechanisms responsible for cold tolerance in crops. The bacterial community structure associated with alpine and Arctic plants was characterized by metataxonomic analyses and taxa associated with cold tolerance were highlighted. Psychrotolerant bacterial endophytes collected from cold-adapted plants improved the shoot growth of tomato seedlings under chilling stress and limited frost damage on apple and strawberry leaves. Bacterium-inoculated plants showed enhanced metabolic changes in response to chilling exposure and recovery, suggesting intimate interactions between psychrotolerant bacteria and the plant host. ... |
