1. A method for silencing a target gene in a plant, comprising, in any order, the steps of:
- (a) abrading a surface of a plant with a particulate of a size greater than about 2.5 micrometers;
(b) applying an RNA to the surface of the plant, wherein the RNA comprises a sequence that is complementary or identical to 21 or more contiguous nucleotides in the sequence of a target gene in the plant;
wherein the particulate, the RNA, or both, are further applied with an osmolyte, andwhereby the target gene is silenced.

6. A method for introducing a nucleic acid into a plant, comprising:
-
(a) in any order, the steps of (i) applying a composition comprising a nucleic acid to a surface of a plant, and (ii) contacting a matrix supporting an abrasive with the surface;
or,(b) in any order, the steps of (i) abrading a surface of a plant with a particulate of a size greater than about 2.5 micrometers, and (ii) applying a composition comprising a nucleic acid to the surface of the plant, wherein the nucleic acid comprises a sequence that is complementary or identical to 21 or more contiguous nucleotides in the sequence of a target gene in the plant; wherein the abrasive or the particulate, or the composition comprising a nucleic acid, or both, are further applied with an osmolyte, and whereby the nucleic acid is introduced into the plant. - View Dependent Claims (7, 8, 9, 10)
