Expression cassettes for regulation of expression in monocotyledonous plants

摘要

The present invention relates to expression cassettes comprising at least one transcription regulating nucleotide sequence obtainable from the group of genes of monocotyle-donous plants consisting of caffeoyl-CoA-O-methyltransferase genes, C8,7-sterol isomerase genes, hydroxyproline-rich glycoprotein (HRGP) genes, lactate dehydrogenase genes, and chloroplast protein 12 like genes. More preferably the transcription regulating sequences are obtainable from Zea mays or Oryza sativa. The transcription regulating sequences are especially useful for root/kernel-preferential, leaf/endosperm-preferential, root/silk/kernel-preferential, or constitutive expression.

主权项

1. An expression cassette for regulating expression in a monocotyledonous plant, said expression cassette comprising:
i) a promoter nucleotide sequence sharing at least 98% sequence identity to the nucleotide sequence of SEQ ID NO:1; ii) at least one nucleic acid sequence which is heterologous in relation to said promoter; and iii) a terminator comprising a nucleotide sequence sharing at least 98% sequence identity to the nucleotide sequence of SEQ ID NO:34; wherein the expression of the at least one nucleic acid sequence is constitutive.
