Nuclear pre-mRNA splicing in plants

摘要: Referee: Dr. Gabor Lazar, Chief, Dept. of Molecular Biology, Massachsetts General Hospital, Harvard Medical School, Wellman Eleven, Boston, MA 02114 The coding regions about 80% plant nuclear genes contain one or more noncoding intervening sequences (introns). transcription these results in a precursor mRNA (pre-mRNA) with (exons) and introns. are then accurately removed the joined nucleus to generate functional mRNAs by process called pre-mRNA splicing. In addition basic/constitutive splicing, many pre-mRNAs, like metazoan undergo alternative thereby contributing proteomic complexity. splicing pre-mRNAs takes place large RNA-protein complex named spliceosome, which is made up several small ribonucleoprotein (snRNP) particles other associated proteins. Until recently, it was thought that there only type spliceosome all eukaryot...
