We have constructed a restriction fragment length polymorphism linkage map for the nuclear genome of the flowering plant Arabidopsis thaliana. The map, containing 90 randomly distributed molecular markers, is physically very dense; greater than 50% of the genome is within 1.9 centimorgans, or approximately 270 kilobase pairs, of the mapped DNA fragments. The map was based on the meiotic segrega...

Notwithstanding the huge amount of detailed information available in protein databases, it is not possible to automatically download a list proteins ordered by position their codifying gene. This order becomes crucial when analyzing common features produced loci or other specific regions human chromosomes. In this study, we developed new procedure that interrogates two databases (genomic and pr...

In order to generate a physical map of Arabidopsis thaliana chromosome 5, 142 molecular markers mapping chromosome 5 have been used in colony hybridization experiments with four Arabidopsis, ecotype Columbia, yeast artificial chromosome (YAC) libraries. This resulted in 634 YAC clones being anchored on chromosome 5. Southern blot analysis confirmed their positioning and provided data, which alo...

The interaction of gonadotropin-releasing hormone (GNRH) and its receptor (GNRHR) is critical in the endocrine regulation of reproduction. The gene (GNRHR) encoding the receptor has been mapped to porcine chromosome 8. There is evidence for three quantitative trait loci (QTL) influencing ovulation rate on this chromosome. We obtained an almost complete sequence (3993 bp, excluding intron 1) of ...

Bread wheat is an allohexaploid consisting of three genetically related (homoeologous) genomes. The homoeologous chromosomes are capable of pairing but strict homologous pairing is observed at metaphase 1. The diploid-like pairing is regulated predominantly by Ph1, a gene mapped on long arm of chromosome 5B. We report direct evidence that a mutant of the gene (ph1b) arose from a submicroscopic ...
