Drought stress-induced physiological and molecular changes in strawberries: an integrated transcriptomic and metabolomic perspective.

ABSTRACT: Strawberry (Fragaria × ananassa) is a nutritionally valuable and widely popular fruit worldwide. Drought stress is a key factor affecting strawberry production; however, previous studies lacked in depth research on the physiological, biochemical, and molecular regulatory mechanism differences among various strawberry varieties. This study systematically examined the physiological and molecular responses of two cultivars, 'Benihoppe' and 'Kaorino', to drought stress. Under mild and severe drought conditions, significant changes were observed in the growth parameters, chlorophyll concentration, antioxidant enzyme activity, and proline accumulation of the two varieties. with 'Kaorino' exhibiting superior drought tolerance compared with 'Benihoppe'.
