The Root Foraging Response under Low Nitrogen Depends on DWARF1-Mediated Brassinosteroid Biosynthesis.

abstract：:The kinetic parameters of auxin transport in suspension-cultured soybean (Glycine max [L.] Merr.) root cells were investigated. The same processes that are responsible for polar indoleacetic acid (IAA) transport in other plant tissues were found to occur in soybean root cells. These include (a) passive diffusion of th...
