Oil palm, a plantation crop of major economic importance in Southeast Asia, is the predominant source edible oil worldwide. We report identification VIRESCENS (VIR) gene, which controls fruit exocarp colour and an indicator ripeness. VIR R2R3-MYB transcription factor with homology to Lilium LhMYB12 similarity Arabidopsis PRODUCTION OF ANTHOCYANIN PIGMENT1 (PAP1). identify five independent mutant alleles over 400 accessions from sub-Saharan Africa that account for dominant-negative virescens...
Oil palm is an important perennial oil crop with extremely long selection cycle of 10 to 12 years. As such, any tool that speeds up its genetic improvement process, such as marker-assisted breeding invaluable. Previously, linkage maps based on AFLP, RFLP and SSR markers were developed QTLs for fatty acid composition yield components identified. High density crosses different backgrounds are indispensable tools investigating genetics. They also useful comparative mapping analyses identify...
Clonal reproduction of oil palm by means tissue culture is a very inefficient process. Tissue culturability known to be genotype dependent with some genotypes being more amenable than others. In this study, genetic linkage maps enriched simple sequence repeat (SSR) markers were developed for dura (ENL48) and pisifera (ML161), the two fruit forms palm, Elaeis guineensis. The SSR mapped onto earlier reported parental based on amplified fragment length polymorphism (AFLP) restriction (RFLP)...
The commercial oil palm (Elaeis guineensis Jacq.) produces a mesocarp (commonly called 'palm oil') with approximately equal proportions of saturated and unsaturated fatty acids (FAs). An increase in FAs content or iodine value (IV) as measure the degree unsaturation would help to open up new markets for oil. One way manipulate acid composition (FAC) is through introgression favourable alleles from American palm, E. oleifera, which has more In this study, segregating oleifera x (OxG) hybrid...
Oil palm (Elaeis guineensis) is the most productive oil bearing crop worldwide. It has three fruit forms, namely dura (thick-shelled), pisifera (shell-less) and tenera (thin-shelled), which are controlled by SHELL gene. The forms exhibit monogenic co-dominant inheritance, where a hybrid obtained crossing maternal paternal palms. Commercial production based on planting thin-shelled palms, typically yield 30% more than while palms female-sterile have little to no yield. clear that hybrids...
Enroute to mapping QTLs for yield components in oil palm, we constructed the linkage map of a FELDA high yielding palm (Elaeis guineensis), hybrid cross. The parents population are Deli dura and pisifera Yangambi origin. cross out-yielded average by 8–21% four trials all which yielded comparably best current commercial planting materials. higher derived from fruit content.

Elaeis guineensis and E. oleifera are the two species of oil palm. is most widely cultivated commercial species, introgression desirable traits from ongoing. We report an improved genome assembly with substantially increased continuity completeness, as well first chromosome-scale assembly. Each was obtained by integration long-read sequencing, proximity ligation optical mapping, genetic mapping. High interspecific conservation observed between species. The study provides extensive gene...
Oil palm breeding involves crossing dura and pisifera palms to produce tenera progeny with greatly improved oil yield. yield is controlled by variant alleles of a type II MADS-box gene, SHELL, that impact the presence thickness endocarp, or shell, surrounding fruit kernel. We identified six novel SHELL in noncommercial African germplasm populations from Malaysian Palm Board. These provide extensive diversity harness genetic, mechanistic phenotypic variation associated globally critical crop....
Abstract Background Molecular breeding has opened new avenues for crop improvement with the potential faster progress. As oil palm is major producer of vegetable in world, its improvement, such as developing compact planting materials and altering oils’ fatty acid composition wider application, important.

Abstract Evaluation of transcriptome data in combination with QTL information has been applied many crops to study the expression genes responsible for specific phenotypes. In oil palm, mesocarp extracted from E. oleifera × guineensis interspecific hybrids is known have lower palmitic acid (C16:0) content compared pure African palms. The present demonstrates effectiveness revealing profiles fatty (FA) and triacylglycerol (TAG) biosynthesis processes hybrids. assembly yielded 43,920 putative...
Abstract The genotyping‐by‐sequencing (GBS) approach was applied to genotype selected interspecific hybrid (F 1 ) and backcross (BC 2 families of Elaeis oleifera guineensis .

Single marker‐trait association analysis identified 47 markers associated with five fatty acid composition (FAC) traits (C16:0, C18:0, C18:1, C18:2 iodine value [IV]) in 12 significant linked oleic...

Oil palm is continually being improved via controlled crossing of selected palms to ensure sustainable yields and productivity. As such, correct parental assignment important as the presence illegitimates will compromise progress improvement. In present study, we determined optimal number microsatellite (SSR) markers for detection in oil crosses with high confidence. Determining assign parentage that DNA fingerprinting be cost effective routine use a quality control tool improvement...
