Physiological and transcriptional analyses of Arabidopsis primary root growth in response to phosphate starvation under light and dark conditions.

ABSTRACT: Plants cope with Pi deficiency by triggering an array of adaptive responses, including the remodeling of root system architecture (RSA). Arabidopsis thaliana grown on a Pi-deficient (-Pi) medium in transparent Petri dishes exhibits an inhibition of primary root (PR) growth. Previous work has shown that direct illumination on roots by blue light is both required and sufficient for the Pi deficiency-induced inhibition of PR growth. However, whether light illumination on shoots of seedlings contributes to the inhibition of PR growth under -Pi condition and whether light signaling pathway is involved in this process remain largely unknown. In addition to Pi deficiency-induced inhibition of PR growth, how light affects the transcriptomic changes under -Pi also remains elusive. Here, we f
