decreased transcription from RNA polymerase II promoter during vegetative growth decreased transcription of amino acid biosynthesis genes midori decreased transcription of amino acid biosynthesis genes during vegetative growth decreased transcription of amino acid biosynthesis genes during mitotic cell cycle 2018-03-19T13:35:26Z reduced transcription of amino acid biosynthesis genes decreased transcription of amino acid biosynthesis genes from RNA pol II promoter A cellular process phenotype observed in the vegetative growth phase of the life cycle in which transcription of amino acid biosynthesis genes from RNA polymerase II promoters occurs to a lower extent than normal. Amino acid biosynthesis genes are those whose products are involved in amino acid biosynthetic processes. FYPO:0006443
