Plant cells accumulate small RNA molecules that regulate plant development, genome
stability, and environmental responses. These small RNAs fall into three major classes …

Global warming has increased the frequency of extreme high temperature events. High
temperature is a major abiotic stress that limits the growth and production of plants …

Plant regulatory small RNAs (sRNAs), which include most microRNAs (miRNAs) and a
subset of small interfering RNAs (siRNAs), such as the phased siRNAs (phasiRNAs), play …

Salinity and drought stresses affect plant growth worldwide and limit crop production. Auxin
is crucial in regulating plants' salinity and drought stress adaptative response. As a chemical …

Plant genomes encode various small RNAs that function in distinct, yet overlapping, genetic
and epigenetic silencing pathways. However, the abundance and diversity of small-RNA …

Abstract MicroRNAs (miRNAs) are∼ 21-nucleotide-long regulatory RNAs that arise from
endonucleolytic processing of hairpin precursors. Many function as essential …

Plants have an extraordinary diversity of transcription machineries, including five nuclear
DNA-dependent RNA polymerases. Four of these enzymes are dedicated to the production …

RNA silencing (RNAi) has a well-established role in anti-viral immunity in plants. The
destructive eukaryotic pathogen Phytophthora encodes suppressors of RNAi (PSRs), which …

Plants are sessile organisms that gauge stressful conditions to ensure survival and
reproductive success. While plants in nature often encounter chronic or recurring stressful …

We have witnessed an explosion in our understanding of the evolution and structure of plant
genomes in recent years. Here, we highlight three important emergent realizations:(1) that …
