摘　　要：Unlike actively moving animals,plants actively change their body architecture via growth of their diverse organs in response to environmental clues and stresses.For example,changes in Arabidopsis thaliana root apex zonation under phosphate(Pi)deficiency is considered to be such an active response,including inhibition of primary root elongation and increasing densities of lateral roots and root hairs(Abel,2017).However,a recent study by Zheng et al.(2019)modifies this hypothesis,which is based on the transparent Petri dish-based culture method of young Arabidopsis seedlings causing illumination of roots.In this issue,Zheng et al.(2019)report that Pi deficiency not only increases malate secretion from Arabidopsis root apices via the ALMT1 transporter but also that blue light(BL)triggers a malate-mediated photo-Fenton reaction in the rhizosphere,increasing the OH radical levels.
