Arabidopsis AAR2, a conserved splicing factor in eukaryotes, acts in microRNA biogenesis

2022-06-26

Abstract excerpt

MicroRNAs (miRNAs) play an essential role in plant growth and development, and as such, their biogenesis is fine-tuned via regulation of the core microprocessor components. Here, we report that Arabidopsis AAR2, a homolog of a U5 snRNP assembly factor in yeast and humans, not only acts in splicing but also promotes miRNA biogenesis. AAR2 interacts with the microprocessor component HYPONASTIC LEAVES1 (HYL1) in the...
