Arabidopsis U11/U12-31K Affects U12-Dependent Intron Splicing.
The splicing patterns of several U12 intron-containing transcripts were analyzed by RT-PCR in wild-type (WT) and four different knockdown plants (amiR1-4, amiR1-6, amiR1-5, and amiR1-8). Identical results were obtained from three independent experiments, one of which is shown. The gray boxes with numbers represent exons, and the dashed and solid lines represent U12 and U2 introns, respectively.
