Seeking to uncover the effects of ethylene on the metabolic process and pectin remobilising capacity of rice (Oryza sativa) that is grown in phosphorus (P)-deficient conditions, Zhu et al. find that ethylene positively regulates the cell wall pectin content of two rice cultivars.
Mediated by the expression of OsPT2, more soluble P was released to the root and translocated to the shoots, and more recycled soluble P and ethylene content was found in cultivar Nipponbare, compared with Kasalath.
This paper is part of the Root Biology Special Issue.
