Abstract

N6-methyladenosine (m6A) is the most common type of eukaryotic mRNA modification. It plays an important role in regulating plant growth and development and stress resistance. m6A modification influences nearly all aspects of RNA metabolism and functionality and has great potential for improving crop quality. However, changing m6A modification levels as a whole may have unpredictable effects, making it impossible to accurately predict the effect of specific m6A modifications on RNA. In this opinion article, the main challenges and possible solutions for exploring m6A modification functions in plant systems are discussed. An m6A editing platform that uses new high-throughput methods to identify m6A modification at single-base resolution, and genome editing for selective editing of specific m6A sites for crop improvement is proposed.

Keywords: CRISPR/Cas13; N(6)-methyladenosine (m(6)A); genome editing; m(6)A editing.
