Abstract Random amplified polymorphic DNA (RAPD) analysis using arbitrary 10‐mer oligonucleotide primers was employed in order to investigate the genetic fidelity of somatic embryogenesis‐derived regenerants oil palm ( Elaeis guineensis Jacq). Clonal palms bearing ‘mantled’ phenotype were identified field and ability RAPD markers distinguish these variants from normal type assessed. Of 387 used, 259 (67%) successfully used amplify genomic fragments with consistently reproducible banding....
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...
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...
In oil palm (Elaeis guineensis Jacq.), ∼5% of somatic embryo-derived regenerants show homeotic changes during floral development, involving an apparent feminization male parts in flowers both sexes, called the 'mantled' phenotype. This variant phenotype is associated with a reduction level global DNA methylation. To explore possible relationships between methylation and accumulation DNA-(cytosine-5) methyltransferase (DNMT) transcripts, full-length coding sequences corresponding to three...
Breeding the oil palm (Elaeis guineensis Jacq.) for climate change requires multidisciplinary and collaborative research by nature: indeed – besides genetics structural functional genomics almost all disciplines related to life sciences are involved. Research work also relies on identification of genetic variation in strategies response stress developed plant: this implies exploration resources provided natural variation, germplasm collections, selected genitors from breeding programs...
The mantled floral phenotype of oil palm (Elaeis guineensis) affects somatic embryogenesis-derived individuals and is morphologically similar to mutants defective in the B-class MADS-box genes. This somaclonal variation has been previously demonstrated be associated a significant deficit genome-wide DNA methylation. In order elucidate possible role methylation transcriptional regulation EgDEF1, APETALA3 ortholog palm, we studied this epigenetic mark within gene parallel with transcript...
The present article is aimed at presenting various types of certification standards which are presentlyor could be -applied to the production palm oil.Doing so, it provides an overview existing mechanisms under way both European and global level addresses controversial issue reliance accuracy standards.The RSPO scheme interesting example such controversies.The case oil reflects recurring mandatory vs. voluntary underlying question respective role public private stakeholders in designing...
PREMISE OF THE STUDY: The genome size of a species (C‐value) is associated with growth, development and adaptation to environmental changes. Angiosperm C‐values range 1200‐fold frequently vary within species, although little known about the impacts domestication on size. Genome variation among related palms evolutionary significance because changes characterize clades may be polyploidy, transposon amplifications, deletions, or rearrangements. Further knowledge will provide crucial...
Date palm (Phoenix dactylifera L.) cv. Khenizi caulogenic meristems were initiated from achlorophyllous leaves excised in vitro shoot cultures and then proliferated on a specific culture medium supplemented with 70 g dm-3 sucrose. Regeneration rates obtained when using standard vitrification, droplet-vitrification, encapsulation-vitrification protocols reached 26.7, 60.0, 40.0 %, respectively. Only explants smaller than 3 mm diameter found to survive cryogenic treatments. Sucrose preculture,...
