Pictogram illustrating the nucleotide sequence flanking the 5' splice site donor in rice. This analysis was done using the sequence from the alternate donor class with a sequence length difference between the two isoforms ranging from 2 bp to 10 bp. The consensus acceptor site is shown at the top (Con).
