Genomics and Plant Breeding
The recent announcements of the breakthroughs in obtaining the oil palm genome sequence map herald a new chapter in oil palm genetic improvement. These breakthroughs will spur the further development of oil palm genomics. This article examines how genomics would impact plant and oil palm breeding. The knowledge derived from genomics research in terms of the DNA structure of a gene, how it funct...
متن کاملGenomics of crop plant genetic resources
Plant genetic resources collection and utilization had made a huge impact in balancing the genetic diversity of the existing crop plant species and their application in genome based studies had also increased widely. Primarily studies were based on model species, although it now enhances the transferability of information to crops and related species. With the tremendous outbreak of new high-th...
متن کاملFrom plant genomics to breeding practice.
New alleles are constantly accumulated during intentional crop selection. The molecular understanding of these alleles has stimulated new genomic approaches to mapping quantitative trait loci (QTL) and haplotype multiplicity of the genes concerned. A limited number of quantitative trait nucleotides responsible for QTL variation have been described, but an acceleration in their rate of discovery...

متن کاملPlant genetic resources management: collection, characterization, conservation and utilization
Genetic resources provide basic material for selection and improvement through breeding to ensure food security needs of the world’s rapidly rising population. Conservation and utilization of plant genetic resources are important components of ex-situ collections. Management of ex-situ collections requires creative and adaptive decisions tailored to operating conditions that are specific and co...
