COMPOSITIONS AND METHODS FOR INCREASING PEST RESISTANCE IN PLANTS

摘要

Compositions and methods of reducing expression of a flavonoid glucosyltransferase plants, and transgenic and hybrid plants with increased pest resistance are disclosed. The plants can express a polynucleotide that alters, reduces, or silences expression of a flavonoid glucosyltransferase. The flavonoid glucosyltransferase can be Glyma07g14530, or a variant, homolog, or ortholog thereof. Compositions and methods for placing a gene of interest under an expression control sequence of Glyma07g14530, or a fragment thereof, and transgenic and hybrid plants containing one or more herbivory-inducible genes are disclosed. The plants can include a polynucleotide having 50, 100, 150, 250, 500, 750, 1,000, 1,250, 1,500, or 2,000 or more nucleotides of an expression control sequence of Glyma07g14530 operable linked to a nucleic acid encoding a gene of interest. The plants can include one or more transgenes or QTLs that increases insect resistance, for example a Bt transgene, or a Pb, QTL-H, or QTL-G.
