Drought stress induced different response mechanisms in three Dendrobium species

Dendrobium has holds a high status and value in traditional Chinese medicine, but its harsh growth environment often leads toinduces drought. However, the molecular mechanism by which Dendrobium resists mechanisms underlying its drought resistance and the impact of drought on its photosynthetic pathway is stillremain unclear.石斛属（Dendrobium）植物在传统中医药中拥有极高的地位与药用价值，但其严苛的生长环境常使其遭受干旱胁迫。然而，其抗旱的分子机制以及干旱对其光合途径的影响目前尚未阐明。
