Abstract
As a chronic stress, salinity is a global issue threatening agricultural production. Salinity stress limits plant yield and product quality. In terms of providing more tools to help to secure food supply in future, new approaches which can improve crop salt tolerance are encouraged. Nanobiotechnology is a promising approach to improve plant salt tolerance. Nano-improved salt tolerance is widely reported in many plant species, including rice, rapeseed, cotton, cucumber and Arabidopsis etc. To better facilitate the usage of nanomaterials in agricultural production, understanding mechanisms behind nano-improved plant salt tolerance could be a useful approach. In this review, we summarized the known mechanism behind nano-enabled plant salt tolerance, from maintaining ROS homeostasis and Na+/K+ ratio to the modulation at the level of hormones and gas signaling molecules. Also, new possible mechanisms of nano-enabled plant salt tolerance are discussed. Overall, this manuscript aims to help people to better understand the mechanisms behind nano-enabled plant salt tolerance.
