Cytokinin is an essential element of the systemic signaling network leading to the enhancement of lateral root proliferation in areas where nitrate is available. Here,we explore more precisely：（i） which particular traits of lateral root growth（density and length of emerged lateral roots） are the targets of systemic signaling in a context of heterogeneous nitrate supply; and（ii） if the systemic signaling depends only on cytokinin or on a combination of several signalings.展开更多
