MicroRNAs (miRNAs) are small RNAs that control gene expression through silencing of
target mRNAs. Mature miRNAs are processed from primary miRNA transcripts by the …

Plant polyphenol oxidases (PPOs) are ubiquitous copper metalloenzymes with a
biochemistry that has been known for more than a century. By the 1990s, biologists began to …

Highlights•Alternative splicing results in multiple mRNA isoforms from a single gene.•Cell

Arabidopsis microRNA expression regulation was studied in a wide array of abiotic stresses
such as drought, heat, salinity, copper excess/deficiency, cadmium excess, and sulfur …

MicroRNAs are small RNAs, 20–22 nt long, the main role of which is to downregulate gene
expression at the level of mRNAs. MiRNAs are fundamental regulators of plant growth and …

In Arabidopsis thaliana, the METTL3 homolog, mRNA adenosine methylase (MTA)
introduces N 6-methyladenosine (m6A) into various coding and noncoding RNAs of the …

Heat stress is one of the major abiotic factors that can induce severe plant damage, leading
to a decrease in crop plant productivity. Despite barley being a cereal of great economic …

Abstract microRNAs (miRNAs) are important regulators of gene expression. After excised
from primary miRNA transcript by dicer-like1 (DCL1, an RNAse III enzyme), miRNAs bind …

Plants as sessile organisms have developed prompt response mechanisms to react to rapid
environmental changes. In addition to the transcriptional regulation of gene expression …

MicroRNAs (miRNAs) are short, single‐stranded, noncoding RNAs that play a crucial role in
basic physiological and morphological processes and in response to various stresses in …
