Enhanced nitric oxide generation in root transition zone during the early stage of cadmium stress is required for maintaining root growth in barley

Background and Aims The objective of this study was to analyse the role of nitric oxide (NO) in relation to reactive oxygen species (ROS) production and root growth inhibition in the early response of barley root tip to cadmium. Methods We used cell-permeable NO-binding dye DAF-2DA for the NO locali...
