From: The leader intron of AtMHX can elicit, in the absence of splicing, low-level intron-mediated enhancement that depends on the internal intron sequence

The LI does not act as a transcriptional enhancer. A. Mean and standard errors of relative GUS activity in mixtures including an equal number of T2 seedlings from 13 independent transformants of each construct. GUS activity of the WT construct was assigned the value of 1. EV, plants expressing the empty vector. The internal graph shows relative GUS activity compared to the WT construct on a smaller scale in plants expressing the constructs that mediated low GUS activity. Statistical analysis (t-test) revealed a highly significant difference (p < 0.01) between plants expressing the WT and all other constructs, but no significant difference was revealed between plants expressing the -Int and the MP+I, MP, I+MP, PIa, or PIb constructs (p > 0.05). B. Representative Northern blot results with the GUS probe. rRNA, ribosomal RNA.
