Abstract
This invention relates to the genetics of gender discrimination in the dioecious date palm. Methods of the present invention involve analyzing DNA or RNA from a date palm plant, tissue, germplasm, or seed for the presence of (i) a nucleic acid sequence or genotype that identifies the sex of the plant, tissue, germplasm, or seed or (ii) a molecular marker in linkage disequilibrium with the nucleic acid sequence or genotype. Also disclosed are kits for selecting male and female date palm plants prior to flowering, methods of breeding a date palm plant, and a method of planting a date palm seed of a known sex.
Claims53
A method of identifying the sex of a date palm plant, said method comprising:
- analyzing DNA or RNA from a date palm plant, tissue, germplasm, or seed for the presence of (i) a nucleic acid sequence that identifies the sex of the plant, tissue, germplasm, or seed or (ii) a molecular marker in linkage disequilibriumwith the nucleic acid sequence and
- identifying the sex of the plant, tissue, germplasm, or seed based on whether or not the plant, tissue, germplasm, or seed contains the nucleic acid sequence or the molecular marker.
A method of identifying the sex of a date palm plant, said method comprising:
- analyzing DNA or RNA from a date palm plant, tissue, germplasm, or seed for the presence of (i) a genotype that identifies the sex of the plant, tissue, germplasm, or seed, or (ii) a molecular marker linked to the genotype and
- identifying the sex of the plant, tissue, germplasm, or seed based on whether or not the plant, tissue, germplasm, or seed contains the genotype or the molecular marker.
A method of selecting a male or female date palm plant prior to flowering, said method comprising:
- detecting in a date palm plant, tissue, germplasm, or seed (i) a genotype that identifies the plant, tissue, germplasm, or seed as male or female, or (ii) a molecular marker in linkage disequilibrium with the genotype and
- selecting the plant, tissue, germplasm, or seed possessing the genotype or the molecular marker.
A kit for selecting a male or female date palm plant prior to flowering, said kit comprising:
- primers or probes for detecting in a date palm plant, tissue, germplasm, or seed (i) a genotype that identifies the plant, tissue, germplasm, or seed as male or female, or (ii) a molecular marker in linkage disequilibrium with the genotype and
- instructions for using the primers or probes for detecting the genotype or the molecular marker.
A method of selecting a male or female date palm plant prior to flowering, said method comprising:
- detecting in a date palm plant, tissue, germplasm, or seed (i) a nucleic acid sequence that identifies the plant, tissue, germplasm, or seed as male or female or (ii) a molecular marker in linkage disequilibrium with the nucleic acid sequence and
- selecting the plant, tissue, germplasm, or seed possessing the nucleic acid sequence or the molecular marker.
A kit for selecting a male or female date palm plant prior to flowering, said kit comprising:
- primers or probes for detecting in a date palm plant, tissue, germplasm, or seed (i) a nucleic acid sequence that identifies the plant, tissue, germplasm, or seed as male or female or (ii) a molecular marker in linkage disequilibrium with the nucleic acid sequence and
- instructions for using the primers or probes for detecting the nucleic acid sequence or the molecular marker.
A method of breeding a date palm plant, said method comprising:
- providing a date palm plant having a sex determined by detecting in the plant or a seed, tissue, or germplasm from which it was derived (i) a genotype that identifies the plant as either male or female, or (ii) a molecular marker in linkage disequilibrium with the genotype and
- breeding the date palm plant with a plant of the opposite sex.
A method of breeding a date palm plant, said method comprising:
- providing a date palm plant having a sex determined by detecting in the plant or a seed, tissue, or germplasm from which it was derived (i) a nucleic acid sequence that identifies the plant as male or female or (ii) a molecular marker in linkage disequilibrium with the nucleic acid sequence and
- breeding the date palm plant with a plant of the opposite sex.
A method of planting a date palm seed of a known sex, said method comprising:
- providing a seed having a known male or female sex and
- planting the seed.
