Nitric oxide alleviates cadmium- but not arsenic-induced damages in rice roots [PDF]

open access: yes, 2020
Nitric oxide (NO) has signalling roles in plant stress responses. Cadmium (Cd) and arsenic (As) soil pollutants alter plant development, mainly the root-system, by increasing NO-content, triggering reactive oxygen species (ROS), and forming peroxynitrite
