The contents of auxin (indole-3-acetic acid, IAA), cytokinins, and abscisic acid (ABA) were determined in explants (megagametophyte embryo), proliferating embryonal-suspensor mass (ESM), non-embryogenic callus Pinus sibirica Larix sibirica. Furthermore, the localization hormones cells was studied with immunohistochemical analysis. It shown that formation embryogenic cultures both species is ass...

In the animal life cycle, the earliest manifestations of programmed cell death (PCD) can already be seen during embryogenesis. The aim of this work was to determine if PCD is also involved in the elimination of certain cells during plant embryogenesis. We used a model system of Norway spruce somatic embryogenesis, which represents a multistep developmental pathway with two broad phases. The fir...

Fertilization of the female gametophyte in angiosperm plants initiates a process of coordinated development of embryo, endosperm, and seed coat that ensures the production of a viable seed. Mutant analysis has suggested that communication between the endosperm and the seed coat is an important determinant in this process. In addition, cell groups within the embryo, derived from the apical and f...
