Abstract

Methods for delayed harvesting of corn fields are provided herein. These methods provide an extended, flexible period of time to harvest corn. The methods allow growers to harvest their corn at the optimal time for drying down or accessing seed, without increasing the risk of losing yield to lodging.

and wherein the second sequence comprises one or more of the 5′ UTR, 1st exon, 1st intron, 2nd exon, 2nd intron, 3rd exon, 3rd intron, 4th exon, 4th intron, 5th exon, 5th intron, 6th exon, 6th intron, 7th exon, 7th intron, 8th exon, 3′ UTR, and any complementary sequence thereof, and any portion of the foregoing, of the endogenous Zm.SAMT gene;
or
(o) a genomic sequence comprising a first sequence and a second sequence;
wherein the first sequence comprises at least 15 consecutive nucleotides of one or more of SEQ ID NOs:
228-235 and 276-283;
wherein the second sequence comprises at least 15 consecutive nucleotides of one or more of SEQ ID NOs:
235-276;
and wherein the genomic sequence is at least 50 consecutive nucleotides in length, and/or fewer than 9000 consecutive nucleotides in length;
or
(p) a recombinant DNA construct comprising a transcribable DNA sequence encoding a GA2 oxidase protein and a plant-expressible promoter, wherein the transcribable DNA sequence is operably linked to the plant-expressible promoter.
