Abstract

Methods, compositions, and kits for predicting and controlling fruit color in palm.

First claim

What is claimed is:

1. A method for determining a fruit color phenotype of an E. guineensis palm plant, the method comprising,
obtaining genotype information for a sample from an E. guineensis palm plant or seed, wherein the genotype information comprises presence or absence of a VIR gene alteration in a genomic region corresponding to SEQ ID NO:1 that comprises a VIR gene and confers a virescens phenotype to fruit,
determining the fruit color phenotype in the E. guineensis palm plant or seed based on the presence or absence of the VIR gene alteration, wherein the gene alteration causes the virescens phenotype, wherein the VIR gene alteration comprises a nucleotide change that results in a premature stop codon; and
segregating the E. guineensis palm plant or seed into groups based on the presence or absence of the VIR gene alternation, wherein at least one group contains E. guineensis palm plants or seeds having the VIR gene alteration in the genomic region corresponding to SEQ ID NO: 1.

2. The method of claim 1 , wherein the VIR gene alteration-generates a truncated protein compared to the protein encoded by SEQ ID NO:4.

3. The method of claim 1 , wherein the VIR gene alteration results in the sequence of any one of SEQ ID NOS:7, 9, 11, 13, and 15, or the VIR gene alteration results in a sequence that encodes an amino acid sequence selected from the group consisting of SEQ ID NOS:5, 8, 10, 12, and 14.

4. The method of claim 1 , wherein the VIR gene encodes a polypeptide at least 95% identical to SEQ ID NO:4.

5. The method of claim 1 , wherein the plant is less than 5 years old.

6. The method of claim 1 , wherein the plant is less than one year old.

7. The method of claim 1 , further comprising selecting the E. guineensis palm plant or seed for cultivation if the E. guineensis palm plant or seed has the VIR gene alteration.

8. The method of claim 7 , wherein the E. guineensis palm plant or seed is discarded if the E. guineensis palm plant or seed does not have the VIR gene alteration.

9. The method of claim 1 , wherein the segregating comprises segregating the E. guineensis palm plant or seed into a first group based on the presence of the VIR gene alteration and segregating the E. guineensis palm plant or seed into a second group based on the absence of the VIR gene alteration.

10. The method of claim 9 , wherein the absence of the VIR gene alteration results in a nigrescens phenotype.

11. The method of claim 1 , wherein obtaining the genotype information comprises detecting the VIR gene alteration by amplification, hybridization, or nucleotide sequencing.

12. A method for determining a fruit color phenotype of an E. guineensis palm plant, the method comprising,
obtaining genotype information for a sample from an E. guineensis palm plant or seed, wherein the genotype information comprises presence or absence of a VIR gene alteration in a genomic region corresponding to SEQ ID NO:1 that comprises a VIR gene and confers a virescens phenotype to fruit,
determining the fruit color phenotype in the E. guineensis palm plant or seed based on the presence or absence of the VIR gene alteration, wherein the gene alteration causes the virescens phenotype, wherein the VIR gene alteration comprises a nucleotide change that results in a premature stop codon, wherein the VIR gene alteration results in the sequence of any one of SEQ ID NOS:7, 9, 11, 13, and 15; and
segregating the E. guineensis palm plant or seed into groups based on the presence or absence of the VIR gene alternation, wherein at least one group contains E. guineensis palm plants or seeds having the VIR gene alteration in the genomic region corresponding to SEQ ID NO: 1.
