The genome sequence of the African oil palm, main source production, is used to predict at least 34,802 genes, including biosynthesis genes; comparison with draft South American palm reveals that two species may have diverged in New World and segmental duplications chromosome arms define palaeotetraploid origin trees. Two papers published this issue Nature deal genetics variants one most important crops use today — Elaeis guineensis its cousin oleifera. Palm accounts for almost half edible...

Marker Assisted Selection (MAS) is well suited to a perennial crop like oil palm, in which the economic products are not produced until several years after planting. The use of DNA markers for selection such crops can greatly reduce number breeding cycles needed. With markers, informed decisions be made at nursery stage, regarding individuals should retained as stock, satisfactory agricultural production, and culled. trait associated with quality, measured terms its fatty acid composition,...

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...

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...

Owing to a rise in frequency and change pattern of cases with fungaemia at our tertiary care centre, we conducted prospective study for 4 months understand the epidemiology outcome this infection. Detailed case histories including management protocol outcomes were noted. Records 140 (27.1% adult 72.9% paediatric patients) analysed. Although C. tropicalis was most common yeast isolated, significantly higher isolation guilliermondii (30.4%) pelliculosa (17.6%) noted patients; albicans (26.3%)...

Abstract Background Oil palm ( Elaeis guineensis Jacq.) is one of the most important oil bearing crops in world. However, genetic improvement through conventional breeding extremely slow and costly, as cycle can take up to 10 years. This has brought about interest vegetative propagation palm. Since introduction tissue culture 1970s, clonal proven be useful, not only producing uniform planting materials, but also development engineering programme. Despite considerable progress improving...

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...

Background and Purpose— Previous clinical studies suggested benefit for poststroke recovery when MLC601 was administered between 2 weeks 6 months of stroke onset. The Chinese Medicine Neuroaid Efficacy on Stroke (CHIMES) study tested the hypothesis that is superior to placebo in acute, moderately severe ischemic within a 72-hour time window. Methods— This multicenter, double-blind, placebo-controlled trial randomized 1100 patients with National Institutes Health Scale score 14, 72 hours...

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)...

Objectives This study aimed to quantify health-related quality of life (HRQoL) loss associated with first episode stroke by comparing patient-reported HRQoL before and after onset. The impact in local population was also evaluated the pre- post-stroke that general population. Methods survivors assessed EQ-5D-3L index score at recruitment, for recalled pre-stroke HRQoL, 3 12 month post-stroke. Change from self-reported 285 238 patients, respectively. Mean EQ each time point (baseline: 464...

In vitro micropropagation based on somatic embryogenesis provides an efficient means to multiply selected genotypes of oil palm (Elaeis guineensis Jacq.). Despite its considerable potential, can yield plants bearing a homeotic flowering abnormality known as mantled. Because the mantled is epigenetic, it cannot be detected with conventional structural molecular markers. Thus, develop discriminating among callus cultures carrying or lacking abnormality, we used gene expression approach. We...

Species-specific simple sequence repeat (SSR) markers are favored for genetic studies and marker-assisted selection (MAS) breeding oil palm improvement. This report characterizes 20 SSR from an Elaeis oleifera genomic library (gSSR). Characterization of the type in 2000 sequences revealed a high percentage di-nucleotides (63.6%), followed by tri-nucleotides (24.2%). Primer pairs were successfully designed 394 E. gSSRs. Subsequent analysis showed ability selected gSSR to reveal diversity...
