Overexpressing HRS1 confers hypersensitivity to low phosphate-elicited inhibition of primary root growth in Arabidopsis thaliana.

Abstract

Phosphate (Pi) deficiency causes dramatic root system architecture (RSA) changes in higher plants. Here we report that overexpression of HRS1 leads to enhanced sensitivity to low Pi-elicited inhibition of primary root growth in Arabidopsis thaliana seedlings. Bioinformatic investigations uncovered that HRS1 and its six homologs encode putative G2-like… (More)
