PHO2, microRNA399, and PHR1 define a phosphate-signaling pathway in plants.

Plant physiology - 1 Jul 2006

Bari Rajendra, Datt Pant Bikram, Stitt Mark, Scheible Wolf-Rüdiger

Abstract excerpt

Inorganic phosphate (Pi)-signaling pathways in plants are still largely unknown. The Arabidopsis (Arabidopsis thaliana) pho2 mutant overaccumulates Pi in leaves in Pi-replete conditions. Micrografting revealed that a pho2 root genotype is sufficient to yield leaf Pi accumulation. In pho2 mutants, Pi does not repress a set of Pi starvation-induced genes, including AtIPS1, AT4, and Pi transporters Pht1;8 and...
