Abstract
Provided are novel compositions for use to herbicide activity. Specifically, the present application describes methods and compositions that modulate the expression of a plastid protein import system of a plant. Also provided are combinations of compositions and methods that enhance weed control.
Claims39
A method of plant control comprising:
- treating a plant or a part of a plant in need of control with a first herbicidal composition comprising a polynucleotide, an effective concentration of an organosilicone surfactant, and a nonpolynucleotide herbicide, wherein the polynucleotide is at least 19 contiguous nucleotides in length and at least 85 percent identical or essentially complementary to a segment of a gene sequence, and wherein a protein encoded by said gene sequence is a component of a chloroplast protein import system, wherein said treated plant is more sensitive to said nonpolynucleotide herbicide contained in said herbicidal composition relative to a similar plant treated with a second herbicidal composition not containing said polynucleotide.

The method of claim 311, wherein said plant is a weedy plant is selected from the group consisting of Abutilon theophrasti, Alopecurus myosuroides, Amaranthus albus, Amaranthus chlorostachys, Amaranthus graecizans, Amaranthus hybridus, Amaranthus lividus, Amaranthus palmeri, Amaranthus rudis, Amaranthus spinosus, Amaranthus thunbergii, Amaranthus viridis, Ambrosia artemisifolia, Ambrosia trifida, Avena fatua, Chenopodium album, Commelina diffusa, Convolvulus arvensis, Conyza canadensis, Cyperus esculentus, Digitaria sanguinalis, Echinochloa colona, Echinochloa crus-galli, Euphorbia heterophylla, Festuca arundinacea, Ipomoea hederacea, Kochia scoparia, Lolium arundinaceum, Lolium multiflorum, Lolium rigidium, Portulaca oleracea, Senna obtusifolia, Setaria viridis, Sorghum halepense, Spirodela polyrrhiza, Taraxacum officinale, Trifolium repens and Xanthium strumarium.
-36. (canceled)
A herbicidal composition comprising an admixture of a polynucleotide and a nonpolynucleotide herbicide, wherein wherein said polynucleotide is essentially identical or essentially complementary to a segment of a gene sequence, wherein a protein encoded by said gene sequence is a component of a chloroplast protein import system selected from the group consisting of a translocon at the outer envelope membrane of a chloroplast (Toc), a translocon at the inner envelope membrane of a chloroplast (Tic), a stroma processing peptidase (SPP), and a chaperone like protein associated with the chloroplast protein import system, wherein said treated plant is more sensitive to said nonpolynucleotide herbicide contained in said herbicidal composition relative to a similar plant treated with a herbicidal composition not containing said nonpolynucleotide polynucleotide.
-40. (canceled)
A polynucleotide molecule applied to the surface of a plant that enhances said plant sensitivity to a glyphosate containing herbicide composition, wherein said polynucleotide comprises is at least 19 nucleotides in length and is homologous or complementary and at least 85 percent identical to a polynucleotide selected from the group consisting of SEQ ID NO:
- 1-1263 and 1584-1638.
