Abstract
This disclosure concerns the use of endogenous plant RNAi machinery to preferentially or specifically reduce transgene expression. In some embodiments, the disclosure concerns specific reduction of transgene expression in male plant tissues, for example, to provide an economical male sterility system of hybrid seed production.
Claims17
A transgenic plant cell comprising a recombinant polynucleotide that encodes an AAD-1 protein that exhibits aryloxyalkanoate dioxygenase activity, wherein said activity enzymatically degrades a phenoxy auxin herbicide and an (R)-aryloxyphenoxypropionate herbicide,
- wherein, an sRNA target site comprising SEQ ID NO:7, or SEQ ID NO:8 is operably linked to the nucleotide sequence encoding the protein encoded by base pairs 1-888 of SEQ ID NO:
- 5.
