Artificial gynogenesis is of great research value in fish genetics and breeding technology. However, existing studies did not explain the mechanism of some interesting phenomena. Severe developmental defects in gynoge...
The genetic variability is considered as the major principle of plant breeding for durum wheat. This variability can be induced in vitro by selection pressure exerted by stress factors such as salinity in order to reg...
