The Root Foraging Response under Low Nitrogen Depends on <i>DWARF1</i>-Mediated Brassinosteroid Biosynthesis

Abstract

significantly improves plant growth and overall N accumulation. Our study reveals that mild N deficiency induces key genes in BR biosynthesis and that natural variation in BR synthesis contributes to the root foraging response, complementing the impact of enhanced BR signaling observed recently. Furthermore, these results suggest a considerable potential of BR biosynthesis to genetically engineer plants with improved N uptake.
