Trichome morphogenesis in Arabidopsis

Trichomes (plant hairs) in Arabidopsis thaliana are large non-secreting epi dermal cells with a characteristic three- dimensional architecture. Because trichomes are easily accessible to a combination of genetic, cell biologic al and molecular methods they have become an ideal model system to study va rious aspects of plant cell morphogenesis. In this review we will summarize recent progress in the understanding of trichome morphogenesis.
