Claims
The disclosure relates to endogenous S-type anion channel genes associated with modified root architecture in plants. It also discloses plants comprising one or more mutations in an endogenous S-type anion channel gene, along with related methods for modifying plant root architecture.
1. A plant, progeny, plant part or plant cell thereof, having a modified root architecture, wherein the plant comprises one or more mutations in an endogenous S-type anion channel gene.
13. A seed or an asexual propagator of the plant according to claim 1.
14. A method for modifying the root architecture of a plant, wherein the method comprises: introducing one or more mutations in a plant endogenous S-type anion channel gene and / or reducing the expression or activity of the endogenous S-type anion channel gene.
24. A method for producing a plant having a modified root architecture, wherein the method comprises: (a) crossing the plant according to claim 1 with itself or another plant to produce seeds; and (b) growing a progeny plant from the seed to produce a plant having a modified root architecture.
26. A crop comprising a plurality of plants according to claim 1 planted together in an agricultural field.
27. A method of producing seeds from a crop, wherein the method comprises: cultivating a plurality of plants according to claim 1 as a crop, and collecting the seeds from the crop, wherein the plants have modified root architecture with respect to a corresponding control plant without the mutation.
33. A method of introgression of a modified root architecture locus into a plant, wherein the method comprises: providing a first plant with the modified root architecture locus, wherein the locus comprises one or more mutations in an endogenous S-type anion channel gene; providing a second plant; crossing the first plant with the second plant to produce a progeny plant population; selecting from the population at least one plant having the modified root architecture locus.
40. A method for identifying or selecting a plant comprising a modified root architecture locus, wherein the method comprises: genotyping at least one plant to detect the presence of one or more mutations in an endogenous S-type anion channel gene or a marker in linkage disequilibrium with it.
