Method of transforming plants
The present invention relates to novel method of vacuum infiltration transformation of plants which provides an increased efficiency of transformation over previously known vacuum infiltration methods, as well as seeds, plants and plant parts transformed with the methods.
1 . A method for increasing transformation efficiency of vacuum infiltration transformation of a plant comprising,
a) transforming a plant with a desired nucleic acid by vacuum infiltration; and
b) removing new flowers formed on said plant after said vacuum infiltration, wherein removing of the new flowers enhances the proportion of transformed seed, which in turn increases transformation efficiency.
2 . The method of claim 1 wherein the increased efficiency results in a transformation efficiency of at least 10%.
3 . The method of claim 2 wherein the increased efficiency results in a transformation efficiency of at least 30%.
4 . The method of claim 3 wherein the increased efficiency results in a transformation efficiency of at least 40%.
5 . The method of claim 3 wherein the increased efficiency results in a transformation efficiency of at least 50%.
6 . The method of claim 1 , wherein the plant is a crop plant selected from the group consisting of corn, rice, soybean, alfalfa, and canola.
7 . The method of claim 1 , wherein the plant is canola.
8 . A method for increasing transformation efficiency of a vacuum infiltration transformation of a plant comprising,
a) transforming a plant with a desired nucleic acid by vacuum infiltration;
b) allowing new flowers to form;
c) performing a second vacuum infiltration on the plant after the formation of new flowers,
wherein the second vacuum infiltration on the plant after the formation of new flowers enhances the proportion of transformed seed, which in turn increases transformation efficiency.
9 . A transformed seed produced by the method of claim 1 .
10 . A plant or plant part produced from the transformed seed of claim 9 .
11 . A canola plant produced by the method of claim 1 .
12 . Oil obtained from a canola plant produced by the method of claim 1.
