Quantitative traits are conditioned by several genetic determinants. Since such genes influence many important complex traits in various organisms, the identification of quantitative trait loci (QTLs) is of major interest, but still encounters serious difficulties. We detected four linked genes within one QTL, which participate in controlling sporulation(More)
Unlinked autosomal microsatellites in six Jewish and two non-Jewish populations were genotyped, and the relationships among these populations were explored. Based on considerations of clustering, pairwise population differentiation, and genetic distance, we found that the Libyan Jewish group retains genetic signatures distinguishable from those of the other(More)
Mango malformation disease (MMD) caused by various Fusaria, including the fungus Fusarium mangiferae, is difficult to diagnose and cannot be controlled effectively. In this study a PCR diagnostic tool was developed for detection of F. mangiferae by generating primers which flank fungus-specific sequences. The assay is suitable for both in-vitro and in-vivo(More)
Amplified Fragment Length Polymorphism (AFLP), Simple Sequence Repeat (SSR) and Single Nucleotide Polymorphism (SNP), were applied to the tomato genome for assessment of polymorphism and for mapping. The polymorphism of AFLP was studied in twenty-one commercial tomato (L. esculentum) varieties. Four AFLP primer combinations produced 298 clear bands; an(More)
Genetic relationships among eight populations of domesticated carp (Cyprinus carpio L.), a species with a partially duplicated genome, were studied using 12 microsatellites and 505 AFLP bands. The populations included three aquacultured carp strains and five ornamental carp (koi) variants. Grass carp (Ctenopharyngodon idella) was used as an outgroup.(More)
A method proposed herein allows simultaneous selection for several production traits, taking into consideration their marginal economic values (i.e. the economic value of a trait's additional unit). This economic index-marker assisted selection (EI-MAS) method is based on the calculation of the predicted economic breeding value (BV), using information on(More)
With the aid of a suitable thin layer chromatographic procedure, the N-6 methyl adenylic acid (m6A), content of a variety of 32P labeled RNA species from HeLa cells has been measured. Poly(A)-containing (poly(A)+) cytoplasmic RNA has on the average one m6Ap per 800 to 900 nucleotides. This value is independent of the length of the molecules. The proportion(More)
