Nucleic acid molecules that target the RHO1 small GTP-binding protein and confer resistance to coleopteran pests
This disclosure concerns nucleic acid molecules and methods of use thereof for control of coleopteran pests through RNA interference-mediated inhibition of target coding and transcribed non-coding sequences in coleopteran pests. The disclosure also concerns methods for making transgenic plants that express nucleic acid molecules useful for the control of coleopteran pests, and the plant cells and plants obtained thereby.
1. A method for controlling a coleopteran pest population, the method comprising:
contacting members of the coleopteran pest population with an agent comprising an inhibitory ribonucleic acid (RNA) molecule expressed from the polynucleotide of SEQ ID NO:109.
2. The method according to claim 1 , wherein the inhibitory RNA molecule is expressed from the polynucleotide in a plant cell.
3. A method for controlling a coleopteran pest population, the method comprising:
providing in a host plant of a coleopteran pest a transformed plant cell comprising the polynucleotide of SEQ ID NO:109 that is transcribed to produce an inhibitory RNA molecule,
wherein the inhibitory RNA molecule functions upon contact with a coleopteran pest belonging to the population to inhibit the expression of a target sequence within the coleopteran pest.
4. The method according to claim 3 , wherein the inhibitory RNA molecule is expressed from the polynucleotide in a plant cell.
5. A method for controlling a coleopteran pest population, the method comprising:
providing in a host plant of a coleopteran pest a transformed plant cell comprising the polynucleotide of SEQ ID NO:109.
6. The method according to claim 5 , wherein the inhibitory RNA molecule is expressed from the polynucleotide in a plant cell.
7. A pest control agent comprising an inhibitory RNA molecule expressed from the polynucleotide of SEQ ID NO: 109, wherein the agent is a topical composition or nutritional composition.
8. A method for controlling a coleopteran pest population, the method comprising:
providing the pest control agent of claim 7 to the coleopteran pest population.
9. The method according to claim 8 , wherein the inhibitory RNA molecule is expressed from the polynucleotide in a plant cell.
