abnormal RNA splicing, via spliceosome altered splice site specificity abnormal splice site specificity 2014-06-24T14:40:45Z midori altered splice site specificity during vegetative growth A cellular process phenotype observed in the vegetative growth phase of the life cycle in which RNA splice site specificity differs from normal. For example, different exons may be included or excluded, or introns in which the normally recognized 3' splice site AG nucleotides are mutated may be spliced. altered splice site specificity during mitotic cell cycle FYPO:0003467
