Abstract:PHO1 proteins play a central role in plant inorganic phosphorus translocation and sensing. The maize (Zea mays ssp. mays) genome encodes two co-orthologs of the ArabidopsisPHO1 gene, designated ZmPho1;2a and ZmPho1;2b. Here, we report the characterization of the transposon-footprint allele Zmpho1;2a'-m1.1, which we refer to hereafter as pho1;2a. The pho1;2a allele is a stable derivative formed by excision of an Activator element from the ZmPho1;2a gene. The pho1;2a allele contains an 8 bp insertion at the poin… Show more
