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. 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.
