Glacial in situ survival in the Western Alps and polytopic autopolyploidy in Biscutella laevigata L. (Brassicaceae).
Past climatic changes and especially the ice ages have had a great impact on both the distribution and the genetic composition of plant populations, but whether they promoted speciation is still controversial. The autopolyploid complex Biscutella laevigata is a classical example of polyploidy linked to glaciations and is an interesting model to explore migration and speciation driven by climate...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Multiscale landscape genomic models to detect signatures of selection in the alpine plant Biscutella laevigata
Plant species are known to adapt locally to their environment, particularly in mountainous areas where conditions can vary drastically over short distances. The climate of such landscapes being largely influenced by topography, using fine-scale models to evaluate environmental heterogeneity may help detecting adaptation to micro-habitats. Here, we applied a multiscale landscape genomic approach...
متن کاملDivergent selection in trailing- versus leading-edge populations of Biscutella laevigata.
BACKGROUND AND AIMS Knowledge on how climate-induced range shifts might affect natural selection is crucial to understand the evolution of species ranges. METHODS Using historical demographic perspectives gathered from regional-scale phylogeography on the alpine herb Biscutella laevigata, indirect inferences on gene flow and signature of selection based on AFLP genotyping were compared betwee...
متن کاملMechanisms and Efficacy of Brassicaceae Seed Meal-induced Disease Control
Development and application of non-fumigant measures for the control of soilborne diseases in field level production systems is limited by the capacity to consistently predict efficacy. Although organic amendments have repeatedly been evaluated for the potential to provide an environmentally sustainable means to manage soilborne diseases, adoption of such methods has been limited to very specif...
