Besides providing.protection ag.inst mechanical damag. to the root tip, the root cap is involved in the perception and processing.of diverse external and internal stimuli resulting.in altered g.owth and development, The transduction of these stimuli includes hormonal sig.aling.pathways such as those of auxin, ethylene and cytokinin. Here, we show that the root cap is essential for the ethylene-induced reg.lation of elong.tion g.owth and root hair formation in maize. Exog.nously applied ethylene is no long.r able to inhibit elong.tion g.owth when the root cap has been surg.cally removed prior to hormone treatment. Reconstitution of the cap positively correlates with the developing.capacity of the roots to respond to ethylene ag.in. In contrast, the removal of the root cap does not per se affect g.owth inhibition controlled by auxin and cytokinin. Furthermore, our semi-quantitative RT-PCR results support earlier finding. that the maize root cap is a site of hig. g.ne expression activity with respect to sensing.and responding.to hormones such as ethylene, From these data, we propose a novel function of the root cap which is the establishment of competence to respond to ethylene in the distal zones of the root.
