(A–C) Wild-type ovules at 1 day after pollination (DAP ... particularly why flowering plants (angiosperms) dominate today’s flora. “Since an unfertilized hypocotyl cannot become a seed in the first ...

They discovered a new "gate" at the chalazal end of the ovule that regulates nutrient transport into the developing seed. "The mechanism was also identified in rice, indicating that it potentially ...

It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth with in the motherplant.

“It was already known that plant life changed toward the end of the Cretaceous, with flowering plants, known as angiosperms, creating more diverse habitats on the ground,” Janis said in the release.

More mammals were living on the ground several million years before the mass extinction event that wiped out the dinosaurs, new research led by the University of Bristol has revealed. The study, ...

"Hell ants may have endured for a long time through the angiosperm terrestrial spread during the Cretaceous, before being decisively affected by geological events toward the end of that period." ...

Nucleul editat a fost apoi transferat într-un ovul denucleat. Oamenii de știință au produs 45 de ovule artificiale, cărora li sa permis să se dezvolte în embrioni în laborator. Acei embrioni au fost ...
