U1 small nuclear RNA is synthesized as a precursor with several extra nucleotides at its 3' end. We show that in Xenopus laevis oocytes, removal of the terminal two nucleotides occurs after the RNA has transited through the cytoplasm and returned to the nucleus. The activity is controlled by an inhibitor of processing, which we call TPI, for 3'-terminal(More)
The inducibility of the glucosinolate resistance mechanism is an energy-saving strategy for plants, but whether induction would still be triggered by glucosinolate-tolerant Plutella xylostella (diamondback moth, DBM) after a plant had evolved a new resistance mechanism (e.g., saponins in Barbara vulgaris) was unknown. In B. vulgaris, aromatic glucosinolates(More)
In Schizosaccharomyces pombe, MBF is a DNA-binding complex suspected to activate the transcription of genes necessary for entry into S phase. The MBF complex contains both p85cdc10 and p72res1/sct1. To obtain a better understanding of how the MBF complex regulates gene expression at the G1/S transition, we have performed a genetic analysis of p72res1. We(More)
