Abstract
Atmospheric nitric oxide (NO) and nitrogen dioxide (NO₂) have long been recognized as either detrimental or beneficial for plant development. Recent research has established that NO is a phytohormone. Our present knowledge of the physiological role of NO₂ is incomplete. We do know, however, that exogenous NO₂ positively regulates the vegetative and reproductive growth of plants. We may therefore postulate that NO₂ is a positive growth regulator for plants. We are now in a position to coherently summarize what is known of NO₂ physiology; collated information on the topic is presented here.Entities:
