The differential expression of Rhopalosiphum padi resistance in sibling wheat-rye amphiploids

Thirteen amphiploids were synthesized by chromosome doubling of an F1 plant of a cross between Triticum aestivum Mianyang11 × S. cereale Kustro, which shows resistance to Bird cherry-oat aphid (Rhopalosiphum padi). The amphiploids were confirmed by GISH analysis and tested for their reaction to R. padi. Eleven amphiploids exhibited resistance to R. padiand two of them exhibited...

Optical microscope gross characterization of rat neonatal testicular germline stem cell expansion in vitro

Neonatal testicular germline stem cell suspension prepared from twenty 3-5 day old albino rats were incubated in normal saline or in NC-01in triplicate groups. A control group of saline alone (without cell suspension) was also prepared. The cell-containing groups and control were incubated for 21 days at room temperature, stained with 50% Mezo (organic) and visually studied daily with a view to histological...
