Methods and compositions for the expression of transgenes in monocot
plants including maize are disclosed. In the invention, gene silencing is
avoided by use of monocot-homeologous sequences from plants of the genus
Coix for transformation. Included in these transgene sequences are Coix
promoters, enhancers, coding sequences and terminators. Suitable
alternatives to maize-derived transgenes are desirable for expression in
maize in that homology-based gene silencing can limit or effectively
eliminate transgene expression.
