Pre-mRNA splicing or the removal of introns from precursor messenger RNAs depends on the accurate recognition of intron sequences by the splicing machinery. We have analyzed various aspects of intron sequence and structure in relation to splice site selection and splicing efficiency of a plant gene AmA1 in Schizosaccharomyces pombe. Earlier, we reported the cloning of AmA1, a seed albumin gene from Amaranthus hypochondriacus [A. Raina, A. Datta, Proc. Natl. Acad. Sci. USA 89 (1992) 11774]. In the absence of an in vitro splicing system for plants, the expression of AmA1 genomic clone in S. pombe has been used to analyze splicing of intron constructs. We aim to focus on S. pombe as a possible alternative and examined its effectiveness as a host for plant gene splicing. The results show here that pre-mRNA transcripts of AmA1 gene underwent splicing in S. pombe.
