Abstract

Splice sites of vertebrate introns are generally not recognized in plant cells. Several lines of evidences have led to the proposal that the mechanism of 3' splice site selection differs in plants and animals (K. Wiebauer, J.J. Herrero, and W. Filipowicz, Mol. Cell. Biol. 8:2042-2051, 1988). To gain a better insight into the mechanistic differences between plant and animal splicing, we constructed chimeric introns consisting partly of dicotyledonous plant and partly of animal intron sequences. Splicing of these chimeric introns was analyzed in transiently transfected tobacco protoplasts. The results show that there are no principal sequence or structural differences between the 3' splice regions of plants and animals. Furthermore, evidence is provided that cooperation between 5' and 3' splice sites takes place and influences their mutual selection.
