From Model Plants to Cannabis: Genetic Regulation of Glandular Trichome Development

Nowadays Cannabis sativa L. is primarily valued for the cannabinoids produced and accumulated in its glandular trichomes. Consequently, it is of special relevance to address studies related to the biochemical, molecular, and morphological panorama of trichomes. This review highlights some of the most recent publications on the morphological, phenological, biochemical and molecular characterization of trichomes and mechanisms underlying their development. Particular emphasis is placed on the transcription factors related to trichome cell identity, drawing on studies conducted in model organisms and in Cannabis sativa L. Finally, we discuss emerging approaches for studying trichomes and highlight biotechnological perspectives that may facilitate future research and crop improvement.
