Temperature-dependent fasciation mutants of Arabidopsis unexpectedly connect mitochondrial RNA processing to the control of cell proliferation during lateral root morphogenesis via electron transport chain activity and reactive oxygen species production.
CPEB4's switch from translational repressor to activator is regulated during cell cycle by hyperphosphorylation of its intrinsically disordered domain, which controls its phase-separation into RNA-containing liquid-like droplets.
Hinokiflavone is identified as a splicing modulator that blocks progression from spliceosome complex A to complex B and inhibits SUMO protease SENP1, causing hyper-SUMOylation affecting 6 U2 snRNP proteins.
Identification of tissue-specific RNA editing using a robust, publicly-available platform (SAILOR) reveals noncoding A-to-I editing events required for proper gene expression and neurological function, significantly advancing the understanding of how ADARs function in neural cells.
Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.
