A traditional karyomorphological approach was carried out in order to investigate the cytotaxonomic relationships among species of Santolina chamaecyparissus complex. All 14 included this complex were analysed for a total 39 populations. Metaphase plates obtained by squashing root tips stained with Feulgen technique. Measurable metaphase available literature also re-analysed. Chromosome number ...
Historical demographic processes and mating systems are believed to be major factors in the shaping of the intraspecies genetic diversity of plants. Among Caryophyllales, the Beta section of the genus Beta, within the Amaranthaceae/Chenopodiaceae alliance, is an interesting study model with species and subspecies (Beta macrocarpa, Beta patula, Beta vulgaris maritima and B.v. adanensis) differin...
P elements inserted at the left end of the Drosophila X chromosome were isolated genetically from wild-type P strains. Stocks carrying these elements were tested for repression of P-strain-induced gonadal dysgenesis in females and for repression of transposase-catalyzed P-element excision in males and females. Both traits were repressed by stocks carrying either complete or incomplete P element...
