RNA modifications constitute an essential layer of gene regulation in living organisms. As the most prevalent internal modification on eukaryotic mRNAs, N 6 -methyladenosine (m 6 A) exists in many plant species and requires the evolutionarily conserved methyltransferases, demethylases, and m 6 A binding proteins for writing, erasing, and reading m 6 A, respectively. In plants, m 6 A affects many aspects of mRNA metabolism, including alternative polyadenylation, secondary structure, translation, and decay, which underlies various plant developmental processes and stress responses. Here, we discuss the recent progress in understanding the roles of m 6 A modification in mRNA metabolism and their mechanistic link with plant development and stress responses. We also highlight some outstanding questions and provide an outlook on future prospects of m 6 A research in plants., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Ltd.

Cys2/His2-type Zinc Finger Proteins (C2H2-ZFPs) are known to play vital roles in the regulation of growth and development in plants. Nevertheless, the underlying molecular network is yet to be established. In this review paper, we elaborate on the structure, classification and biological functions of C2H2-ZFPs, and focus on the molecular mechanism of C2H2-ZFPs in regulating plant growth and development, to provide theoretical support for crop cultivation and breeding.
