• Background and aims Much recent study of plant trichomes has focused on various aspects of glandular secreting trichomes (GSTs) and differentiation of simple trichomes. This Botanical Briefing will highlight:
- research on various aspects of, and manipulation of glandular secreting trichomes;
- molecular aspects of the differentiation and development of simple trichomes of arabidopsis and cotton;
- how methods for manipulation of model systems used in the above work can be applied to expand our understanding of less studied surface structures of plants.
• Scope The Briefing will cover:
- established and suggested roles of simple and glandular secreting trichomes;
- recent results regarding solute and ion movement in trichomes;
- methods for isolating trichomes;
- recent studies of trichome differentiation and development;
- attempts to modify metabolism in secreting trichomes;
- efforts to exploit trichomes for commercial and agronomic purposes.
Keywords: Plant secretion, simple trichomes, glandular trichomes, secreted phytochemicals, arabidopsis, tobacco, gene library, pest resistance, molecular farming, trichome differentiation, trichome functions.
