Progress in Research of Plant Trichome

doi:10.11983/CBB17078

Abstract

Abstract: Trichomes are specialized structures that originate from epidermal cells in the aerial organs of most plants. Trichomes serve as a physical barrier on plant surfaces against many biotic and abiotic stresses, playing an important role in plant growth and development. Some trichomes have economic importance. In recent years, new genes related to trichome development in different plants have been isolated, for great strides in the understanding of molecular mechanisms underlying trichome development and regulation. This review focuses on recent research progress in trichome development and discusses the future study and utilization of plant trichomes.

Key words: trichome, physical barrier, development, genes, molecular mechanisms
