Root hair and xylem are part of the same

WebThe xylem forms the plumbing of a plant, allowing water to travel along the roots, up the stem, and across the leaves. The conducting cells of the xylem – tracheids and vessel elements (also called vessel members) – have the remarkable feature that they perform their main physiological role when they are dead. WebFeb 17, 2014 · This root-derived signal (called Q in the original AON model of Gresshoff and Delves ) is transmitted via the xylem to the shoot where its perception leads to the formation of another signal, called the shoot-derived inhibitor (SDI) [19,35]. This is then transported back to the roots where it acts to inhibit further nodulation by arresting ...
