Plant Glandular Trichomes: Natural Cell Factories of High Biotechnological Interest

[GMO]

A Detailed Understanding of Glandular Trichome Initiation and Development Is Currently Missing

A complete circuit for glandular trichome formation and patterning in the leaf epidermis will require a sound understanding of their initiation process in the plant protodermis and of the subsequent developmental steps leading to the formation of a polarized and specialized multicellular structure, of the genes that regulate cell division, participate in cell signaling, and promote specialized cell fate (Fig. 1). It also requires an understanding of how this developmental regulatory network affects cellular biological targets such as the core cell cycle machinery. A particularly large gap in our current knowledge is the identification of regulators of entry into the glandular trichome cell fate and of progression through the pathway.
