HIGH NITROGEN INSENSITIVE 9 (HNI9)-mediated systemic repression of root NO 3 − uptake is associated with changes in histone methylation

In plants, root nitrate uptake systems are under systemic feedback repression by the N satiety of the whole organism, thus adjusting the N acquisition capacity to the N demand for growth; however, the underlying molecular mechanisms are largely unknown. We previously isolated the Arabidopsis high ni... View More
