The oil palm (Elaeis guineensis Jacq.) is a perennial monocotyledonous tropical crop species that now the world's number one source of edible vegetable oil, and richest dietary provitamin A. While new elite genotypes from traditional breeding programs provide steady yield increases, long selection cycle (10-12 years) large areas required to cultivate make genetic improvement slow labor intensive. Molecular have potential significant impacts on rate but limited molecular resources, in...
We searched for quantitative trait loci (QTL) associated with the palm oil fatty acid composition of mature fruits E. guineensis Jacq. in comparison its wild relative oleifera (H.B.K) Cortés. The cross LM2T x DA10D between two heterozygous parents was considered our experiment as an intraspecific representative guineensis. Its QTLs were compared to published same traits interspecific Elaeis pseudo-backcross used indirect oleifera. Few correlations found pulp proportions and yield traits,...
A quantitative trait locus (QTL) analysis designed for a multi-parent population was carried out and tested in oil palm (Elaeis guineensis Jacq.), which is diploid cross-fertilising perennial species. new extension of the MCQTL package especially crosses between heterozygous parents. The algorithm, now available any allogamous species, used to perform compare two types QTL search small size families, within-family across-family analysis, using data from 2 x complete factorial mating...
Abstract A (GA) n microsatellite‐enriched library was constructed and 16 nuclear simple sequence repeat (SSR) loci were characterized in Phoenix dactylifera . Across‐taxa amplification genotyping tests showed the utility of most SSR markers 11 other species transferability some them Elaeis guineensis , Pritchardia Pritchardiopsis jeanneneyi six Astrocaryum The first to be published for P. these new resources are available cultivar identification, pedigree analysis, germplasm diversity as...
The oil palm fruit mesocarp contains high lipase activity that increases free fatty acids and necessitates post-harvest inactivation by heat treatment of bunches. Even before the causes consequential losses requires costly measures to limit quantities. Here we demonstrate elite low-lipase lines yield with substantially less than standard genotypes, allowing more flexibility for processing extended ripening increased yields. We identify its gene cosegregates low-/high-lipase trait, providing...
We chose an Elaeis interspecific pseudo-backcross of first generation (E. oleifera × E. guineensis) guineensis to identify quantitative trait loci (QTLs) for fatty acid composition palm oil. A dense microsatellite linkage map 362 spanned 1.485 cM, representing the 16 pairs homologous chromosomes in genus from which we traced segregating alleles both and grandparents. The relative linear orders mapped suggested probable absence chromosome rearrangements between genomes. total 19 QTL...
The results of the development oil palm (Elaeis guineensis Jacq.) microsatellite markers are given step by step, from screening libraries enriched in (GA)n, (GT)n, and (CCG)n simple-sequence repeats (SSRs) to final characterisation 21 SSR loci. Also published primer sequences, estimates allele size range, expected heterozygosity E. closely related species oleifera, which an optimal utility was observed. Multivariate data analyses showed ability efficiently reveal genetic-diversity structure...
Fourteen microsatellite loci of Phoenix dactylifera were targeted to examine the genetic diversity in Tunisian date-palms germplasm. They showed a high level polymorphism 49 accessions from three main oases with little geographic structure within Tunisia. The data agrees previous analyses germplasm using other molecular markers. 100% local successfully fingerprinted and easily distinguished by help only loci. possibility microsatellites for large scale labelling offshoots vitro plantlets...
Abstract A (GA) n and (GT) microsatellite‐enriched library was constructed 23 nuclear simple sequence repeat (SSR) loci were characterized in the guava species ( Psidium guajava L.). All SSR found to be polymorphic after screening for diversity different cultivars, across‐taxa amplification tests showed potential transferability of most markers three other species. First published P. , this new resource will a powerful tool genetic studies guava, including cultivars identification linkage...
Malaria is a major human parasitic disease caused by four species of Plasmodium protozoa. vivax , the most widespread, affects millions people across Africa, Asia, Middle East, and Central South America. We have studied genetic variability 13 microsatellite loci in 108 samples from 8 localities America, New Guinea. Only one locus polymorphic; nine are completely monomorphic, remaining three monomorphic all but or two populations, which rare second allele. In contrast, falciparum displays...
The methylation-sensitive amplification polymorphism (MSAP) technique has been employed on somatic embryo-derived oil palms (Elaeis guineensis Jacq.) to identify methylation polymorphisms correlated with the "mantled" somaclonal variation. variant phenotype displays an unstable feminization of male organs in both and female flowers. Using MSAP, status CCGG sites was compared three normal versus mantled regenerants sampled clonal populations obtained through embryogenesis from four...
The guava accessions assembled in the Cuban germplasm collection at Alquizar (Havana Province) were previously characterized by phenotypic descriptors as well AFLP DNA markers (Rodriguez et al., 2004; Valdes-Infante 2003). Here, SSR applied establishment of phylogenetic relationships. Furthermore, three mapping populations produced controlled crosses with dwarf cultivar 'Enana Roja cubana' female parent. Based on segregating markers, an integrated molecular linkage map was constructed for...

Cuticular waxes were extracted from the leaves of a coconut mapping population generated by controlled cross an East African Tall and Rennell Island genotype for construction molecular linkage maps. The wax composition was analyzed capillary gas chromatography/mass spectrometry, eight compounds, their absolute relative amounts determined. As reported previously different ecotype (Malayan Yellow Dwarf), lupeol methyl ether, isoskimmiwallin, skimmiwallin identified as major components...
The allelic diversity within oil palm populations (45 native ones from 10 African countries, three breeding and one collection of semi-wild material) was determined using 16 microsatellite markers. A total 209 alleles were detected, with a mean number 13.1 per locus. effective locus ( e ) 3.3 ± 1.3. Although the Duncan's multiple range test only separated group Madagascar rest on basis , presence unique rare high values suggest that 23 should be conserved to secure diversity.
An integrated parental linkage map of guava (Psidium guajava L., 2n = 22) based on AFLP and SSR markers has been constructed for the mapping population MP1 derived from a cross between two heterozygous cultivars (Enana x N6). A total 1103 segregating obtained 119 primer combinations were produced mapping. In addition, 171 maker loci analysed which generated 258 allelic fragments. 1364 available The contains 578 (452 AFLPs, 126 SSRs) distributed 11 groups corresponding to chromosomes haploid...
