Direct Toxicity

Plant trichomes constitute a first line of defence against insect herbivores. The pre- and post-ingestive defensive functions of glandular trichomes are well documented and include direct toxicity, adhesion, antinutrition and defence gene induction. By contrast, the defensive functions of non-glandular trichomes are less well characterized, although these structures are thought to serve as physical barriers that impede herbivore feeding and movement. We experimentally varied the density of stellate non-glandular trichomes in several ways to explore their pre- and post-ingestive effects on herbivores. Larvae of Manduca sexta (Sphingidae) initiated feeding faster and gained more weight on Solanum carolinense (Solanaceae) leaves having lower trichome densities (or experimentally removed trichomes) than on leaves having higher trichome densities. Adding trichomes to artificial diet also deterred feeding and adversely affected caterpillar growth relative to controls. Scanning electron and light microscopy revealed that the ingestion of stellate trichomes by M. sexta caterpillars caused extensive damage to the peritrophic membrane, a gut lining that is essential to digestion and pathogen isolation. These findings suggest that, in addition to acting as a physical barrier to deter feeding, trichomes can inhibit caterpillar growth and development via post-ingestive effects.

Trichome Types

Plant trichomes are epidermal outgrowths of varying size and form. While the chemical defensive function of the secretory trichomes is well established, the biomechanical function of the non-glandular trichomes emerges as another major defensive strategy of plants. In particular, trichomes impede the locomotion of insect herbivores both by serving as a physical barrier and by wounding them. Solanaceous trichomes are often viewed as a model for the trichome development and defensive function. In particular, trichomes in tomato and relative species have been extensively examined, with different trichome types being precisely described. This review attempts to summarize the knowledge on trichomal defense and biomechanics, with a special emphasis on Solanaceae species, and suggests several avenues for future research.

An investigation into the ultrastructure and histochemistry of glandular trichomes of johnsongrass [Sorghum halepense (L.) Pers.] leaves

Secretory Apparatus

Secretory trichomes have been described on johnsongrass leaves previously, but there is little knowledge of their ultrastructure or the nature of their secretion. Since johnsongrass is a pernicious weed, there is much interest in the nature of compounds found on its foliar surface, and the possible effect of these extrusions on herbicide efficiency. This report describes the results of an investigation into the ultrastructure of the secretory apparatus, and into the nature of the secretion.
