Abstract Recent polyploidy in gymnosperms is unusually scarce being present only 9.80 % of the 714 taxa studied cytologically. Polyploid forms are represented by sporadic seedlings and individual trees, intraspecific cultivation or wild entirely polyploid species genera. Polyploidy shows a non-random distribution different genera mostly prevalent Ephedra Juniperus , besides classic examples Seq...

The Role of Polyploidy in the Evolution of Gender Dimorphism: An Experimental Approach Using Fragaria vesca Allison Kwok Advisor: University of Guelph, 2013 Dr. Brian C Husband The evolution of gender dimorphism is associated with the incidence of polyploidy in several plant taxa, but the underlying causes of this relationship are not well understood. Here I investigate the direct and indirect ...

Polyploidy means having more than two basic sets of chromosomes. Polyploid plants may be artificially obtained through chemical, physical and biological (2n gametes) methods. This approach allows an increased gene scope expression, thus resulting in phenotypic changes such as yield product quality. Nonetheless, breeding new cultivars induced polyploidy should overcome deleterious effects that a...

Tyrosine kinase inhibitor BMS-777067 is an inhibitor of RON/MET receptor tyrosine kinases currently under clinical trials. Here, we report the synergistic activity of BMS-777607 in combination with mTOR inhibitor AZD8055 in killing chemoresistant pancreatic cancer and cancer stem cells. Treatment of pancreatic cancer L3.6pl cells with BMS-777607 alone inhibited clonogenic growth and moderately ...
