Role of Trichomes in Plant Stress Biology

In this chapter, we will examine the role of trichomes in plant stress biology. Trichomes have been long studied as the first line of defense against herbivores. We review the studies that have examined the structure, classification, and diversity of trichomes in flowering plants, followed by their modes of action against abiotic and biotic stressors. We also review the studies on herbivore X trichome interactions and how trichomes play a role in both direct and indirect plant defenses. Next, we use results from our research to highlight the importance of trichomes as an effective measure of plant defense and how genetic variation affects trichome-mediated defenses. And, finally we propose some exciting new areas of research on trichomes and trichome-mediated defenses for future work.
