Abstract excerpt
In rice (Oryza sativa) seedlings, continuous white-light irradiation inhibited the growth of seminal roots but promoted the growth of crown roots. In this study, we examined the mechanisms of photoinhibition of seminal root growth. Photoinhibition occurred in the absence of nitrogen but increased with increasing nitrogen concentrations. In the presence of nitrogen, photoinhibition was correlated with coiling of...
