Abstract:
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. In this review, we discuss the spatial and temporal regulatory networks and cross-talk between phytohormones and epigenetic modifications in the regulation of trichome and root hair initiation in Arabidopsis. The discussion in this review provides a good model for understanding the regulatory mechanism of cell differentiation processes in plants. Moreover, we summarize recent advances in the modulation of trichome and root hair initiation in plants and compare different regulatory mechanisms to help illuminate key goals for future research.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
