New approaches for studying and exploiting an old protuberance, the plant trichome.
OBJECTIVE
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.


METHODS
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.
