We searched for quantitative trait loci (QTL) associated with the palm oil fatty acid composition of mature fruits of the oil palm E. guineensis Jacq. in comparison with its wild relative E. oleifera (H.B.K) Cortés. The oil palm cross LM2T x DA10D between two heterozygous parents was considered in our experiment as an intraspecific representative of E.(More)
The oil palm fruit mesocarp contains high lipase activity that increases free fatty acids and necessitates post-harvest inactivation by heat treatment of fruit bunches. Even before heat treatment the mesocarp lipase activity causes consequential oil losses and requires costly measures to limit free fatty acids quantities. Here we demonstrate that elite(More)
Grapevine (Vitis vinifera), the genome sequence of which has recently been reported, is considered as a model species to study fleshy fruit development and acid fruit physiology. Grape berry acidity is quantitatively and qualitatively affected upon increased K(+) accumulation, resulting in deleterious effects on fruit (and wine) quality. Aiming at(More)
We chose an Elaeis interspecific pseudo-backcross of first generation (E. oleifera × E. guineensis) × E. guineensis to identify quantitative trait loci (QTLs) for fatty acid composition of palm oil. A dense microsatellite linkage map of 362 loci spanned 1.485 cM, representing the 16 pairs of homologous chromosomes in the Elaeis genus from which we traced(More)
The grape berry provides a model for investigating the physiology of non-climacteric fruits. Increased K(+) accumulation in the berry has a strong negative impact on fruit acidity (and quality). In maturing berries, we identified a K(+) channel from the Shaker family, VvK1.2, and two CBL-interacting protein kinase (CIPK)/calcineurin B-like calcium sensor(More)
The Ribosomal DNAs of Helianthus annuus and H. argophyllus were analysed. Total DNA from single individuals of six cultivated lines, one wild ecotype ofH. annuus, and three ecotypes of H. argophyllus, were digested with various restriction enzymes. Hybridisation of Southern blots with sunflower ribosomal probes containing most of the interspacer regions(More)
