Two hallmark features of meiosis are i) the formation of crossovers (COs) between homologs and ii) the production of genetically-unique haploid spores that will fuse to restore the somatic ploidy level upon fertilization. In this study we analysed meiosis in haploid Arabidopsis thaliana plants and a range of haploid mutants to understand how meiosis progresses without a homolog. Extremely low c...
A series of aggregation-deficient (aggregateless) mutants were isolated in genetically marked haploid strains of the cellular slime mould Dictyostelium discoideum. Diploids were produced from pairs of such haploid mutants by a fusion system based on this organism's parasexual cycle. The diploids were isolated from the haploids by using complementation of non-allelic growth-temperature-sensitive...
Quantitative trait loci (QTL) mapping is a powerful tool for investigating the genetic basis of natural variation. QTL can be mapped using a number of different population designs, but recombinant inbred lines (RILs) are among the most effective. Unfortunately, homozygous RIL populations are time consuming to construct, typically requiring at least six generations of selfing starting from a het...
