Ammonia borane positively regulates cold tolerance in Brassica napus via hydrogen sulfide signaling.

ABSTRACT:

Background

Cold stress adversely influences rapeseeds (Brassica napus L.) growth and yield during winter and spring seasons. Hydrogen (H₂) is a potential gasotransmitter that is used to enhance tolerance against abiotic stress, including cold stress. However, convenience and stability are two crucial limiting factors upon the application of H₂ in field agriculture. To explore the application of H₂ in field, here we evaluated the role of ammonia borane (AB), a new candidate for a H₂ donor produced by industrial chemical production, in plant cold tolerance.

Results

The application with AB could obviously alleviate the inhibition of rapeseed seedling growth and reduce the oxidative damage caused by cold stress. The above physiological
