In most taxa of plant and animal kingdoms the initial steps of embryogenesis and the final morphology of an organism are strongly determined. However, these two phenomena do not correlate from phylogenetic point of view, namely, different unrelated taxa can have the same type of early embryogenesis, while there can be different types of cleavage in...

Along with a strict determinism of early embryogenesis in most living organisms, some of them exhibit variability of cell fates and developmental pathways. Here we discuss the phenomena of determinism and variability of developmental pathways, defining its dependence upon cell potency, cell sensitivity to the external signals and cell signaling. We...

The process of morphogenesis is an evolution of shape of an organism together with the differentiation of its parts. This process encompasses numerous biological processes ranging from embryogenesis to regeneration following crisis such as amputation or transplantation. A fundamental theoretical question is where exactly do these instructions for (...

Cardiocrinum cordatum (Thunb.) Makino var. glehnii (F. Schmidt) Hara (Liliaceae) a rare species is characterized by an underdeveloped embryo during dissemination and by the difficulty of seed germination. The aim of the work was to clarify the type of seed dormancy and optimization of seed reproduction in this species by combining various methods:...

In the conditions of temperate climate, a certain reproductive strategies were developed in plants. Seed dormancy and connected with it the phenomenon of embryo postdevelopment after dissemination are considered to be one of these strategies. This phenomenon is noted in plants from various climatic zones, differing in life cycles and types of dorma...
