In plants, cell fate determination is regulated temporally and spatially via a complex of signals consisting of a large number of genetic interactions. Trichome and root hair formation are excellent models for studying cell fate determination in plants. Nowadays, the mysteries underlying the reprograming of trichome and root hair and how nature programs the development of trichome and root hair is an interesting topic in the scientific field.

Sweet wormwood (Artemisia annua), an annual herb belonging to the Compositae family, is the main source of the potent anti-malarial drug artemisinin, which is mainly produced in glandular trichomes of A. annua leaves. The WD40 protein family is one of the largest protein families in eukaryotes and plays crucial roles in regulating plant growth and development, stress responses, and secondary metabolite biosynthesis.
