In general, there is no known way to produce a tree with an optimal shell phenotype: when a tree with an optimal shell phenotype is crossed with itself or with another tree with an optimal shell phenotype (will only produce ) seeds with optimal shell phenotype

Embodiment 1

[0150] Example 1. Recognition of alleles 3-11, corresponding to nucleotide sequences SEQ ID NOs: 12-21 and polypeptides SEQ ID NOs: 3-11

[0151] We previously reported homozygous (eg AVROS / AVROS, MPOB / MPOB or AVROS / MPOB) and tenera oil palm fruit phenotypes, heterozygotes with one wild-type dura allele (eg AVROS / dura or MPOB / dura), AVROS and MPOB mutations in exon 1 of the SHELL gene are responsible for the pisifera oil palm fruit phenotype. While tenera oil palm is the preferred phenotype for commercial oil palm production, it is difficult to completely prevent the emergence of wild-type dura palm in commercial populations. To assess the extent of dura contamination within commercial oil palm populations and to search for new alleles of the SHELL gene that produce the pisifera / tenera AVROS and sh MPOB ) tested 5,158 oil palm trees from 6 different smallholders in Malaysia for the presence of AVROS and / or MPOB alleles using an allele-specific PCR assay. As expected, most p...

Abstract

The present invention discloses sequences of nucleotides and polypeptides for predicting and controlling shell phenotypes of palms.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 180,042, filed June 15, 2015, the contents of which are hereby incorporated by reference in their entirety for all purposes. Background technique [0003] Oil palms (African oil palm and American oil palm) can be divided into different groups according to their fruit characteristics, and there are 3 naturally occurring fruit types that differ in shell thickness and oil production. Dura type palms are homozygous for the wild-type allele of the shell gene (sh + / sh + ), has a thick seed coat or shell (2-8 mm) and produces about 5.3 tons of oil per hectare per year. Tenera type palms are heterozygous for the wild-type and mutant alleles of the shell gene (sh + / sh - ), has a relatively thin shell surrounded by a pronounced fibrous annulus, and produces about 7.4 tons of oil per hectare per year. Finally, the pisifera type of palm is homozygous for th...
