Abstract
Reversible regulation of N6-methyladenosine (m6A) methylation of eukaryotic RNA via methyltransferases is an important epigenetic event affecting RNA metabolism. As such, m6A methylation plays crucial roles in regulating animal growth, development, reproduction, and disease progression. Herein, we review the latest research advancements in m6A methylation modifications and discuss regulatory aspects in the context of growth, development, and reproductive traits of livestock. New insights are highlighted and perspectives for the study of m6A methylation modifications in shaping economically important traits are discussed.

Detection, distribution, and functions of RNA N 6-methyladenosine (m 6A) in plant development and environmental signal responses. FRONTIERS IN PLANT SCIENCE 2024; 15:1429011. [PMID: 39081522 PMCID: PMC11286456 DOI: 10.3389/fpls.2024.1429011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Accepted: 06/24/2024] [Indexed: 08/02/2024]
Abstract
The epitranscriptomic mark N 6-methyladenosine (m6A) is the most common type of messenger RNA (mRNA) post-transcriptional modification in eukaryotes. With the discovery of the demethylase FTO (FAT MASS AND OBESITY-ASSOCIATED PROTEIN) in Homo Sapiens, this modification has been proven to be dynamically reversible. With technological advances, research on m6A modification in plants also rapidly developed. m6A modification is widely distributed in plants, which is usually enriched near the stop codons and 3'-UTRs, and has conserved modification sequences. The related proteins of m6A modification mainly consist of three components: methyltransferases (writers), demethylases (erasers), and reading proteins (readers). m6A modification mainly regulates the growth and development of plants by modulating the RNA metabolic processes and playing an important role in their responses to environmental signals. In this review, we briefly outline the development of m6A modification detection techniques; comparatively analyze the distribution characteristics of m6A in plants; summarize the methyltransferases, demethylases, and binding proteins related to m6A; elaborate on how m6A modification functions in plant growth, development, and response to environmental signals; and provide a summary and outlook on the research of m6A in plants.

Abstract
N6-methyladenosine (m6A) is the most abundant modification observed in eukaryotic mRNAs. Advances in transcriptome-wide m6A mapping and sequencing technologies have enabled the identification of several conserved motifs in plants, including the RRACH (R = A/G and H = A/C/U) and UGUAW (W = U or A) motifs. However, the mechanisms underlying deposition of m6A marks at specific positions in the conserved motifs of individual transcripts remain to be clarified. Evidence from plant and animal studies suggests that m6A writer or eraser components are recruited to specific genomic loci through interactions with particular transcription factors, 5-methylcytosine DNA methylation marks, and histone marks. In addition, recent studies in animal cells have shown that microRNAs play a role in depositing m6A marks at specific sites in transcripts through a base-pairing mechanism. m6A also affects the biogenesis and function of chromatin-associated regulatory RNAs and long noncoding RNAs. Although we have less of an understanding of the link between m6A modification and epigenetic factors in plants than in animals, recent progress in identifying the proteins that interact with m6A writer or eraser components has provided insights into the crosstalk between m6A modification and epigenetic factors, which plays a crucial role in transcript-specific methylation and regulation of m6A in plants.

Abstract
Epigenetics-mediated breeding (Epibreeding) involves engineering crop traits and stress responses through the targeted manipulation of key epigenetic features to enhance agricultural productivity. While conventional breeding methods raise concerns about reduced genetic diversity, epibreeding propels crop improvement through epigenetic variations that regulate gene expression, ultimately impacting crop yield. Epigenetic regulation in crops encompasses various modes, including histone modification, DNA modification, RNA modification, non-coding RNA, and chromatin remodeling. This review summarizes the epigenetic mechanisms underlying major agronomic traits in maize and identifies candidate epigenetic landmarks in the maize breeding process. We propose a valuable strategy for improving maize yield through epibreeding, combining CRISPR/Cas-based epigenome editing technology and Synthetic Epigenetics (SynEpi). Finally, we discuss the challenges and opportunities associated with maize trait improvement through epibreeding.
