Compositions and methods for increasing methionine content in plants
View Patent ↗Compositions and methods are provided for increasing methionine content in plants are disclosed.
1. A vector comprising an RNAi effective to down modulate expression of methionine gamma lyase in a target plant, thereby increasing methionine content in plant cells expressing said RNAi, wherein said RNAi is SEQ ID NO: 1.
2. The vector comprising the RNAi of claim 1 wherein said RNAi is operably linked to at least one regulatory sequence.
3. A method for producing a potato plant having increased methionine content in tubers comprising
a) transforming a potato plant cell with the RNAi of claim 1 , and regenerating a plant from the transformed plant cell.
4. A method for transforming a cell comprising transforming a cell with the RNAi of claim 1 .
5. A potato plant cell comprising the RNAi of claim 1 .
6. A potato plant produced from the transformed potato plant cell of claim 3 .
7. A seed comprising the RNAi of claim 1 .
8. A method for increasing methionine content in potatoes comprising:
(a) transforming potato plant cells with the RNAi of claim 1 ;
(b) growing fertile mature plants from the transformed plant cells obtained from step (a) under conditions suitable to obtain potatoes; and
(c) harvesting potatoes containing increased levels of methionine compared to potatoes obtained from plants lacking said RNAi.
