... Plants have evolved remarkable adaptations that allow them to tolerate harsh environmental conditions [1,2] and to shape their interactions with other organisms, whether it be communicating with other plants in the community [3], attracting mutualistic partners such as pollinators [4][5][6], or deterring antagonistic individuals such as herbivores [7,8]. Many of these adaptations involve metabolites that are delivered through diverse secretory structures, such as nectaries, stinging hairs, and osmophores [9][10][11][12]. In general, secretion refers to the release of substances from the protoplast [13] and sometimes includes localization of substances within the cell [14]. ...

... Herborized leaves were rehydrated following the herborization reversal protocol of Smith and Smith (1942). They were subsequently dehydrated in a Butyl alcohol series and embedded in histological paraffin (Johansen 1940). After embedding, transverse histological sections of the leaf fragments were prepared using a rotary microtome (LUPETEC MRP09), with an average thickness of 10-12 µm. ...
