Perhaps, behind androgenesis there is just an alternative survival mechanism based on the totipotency of plant cells and on the capacity of primitive plants to develop a haploid multicellular structure during the extended haploid phase of their life cycle.
Since the cells are being dedifferentiated to the pluripotent stage, a technical issue will be regulating the process so the cells do not continue on to totipotency, at which point the question of embryo destruction arises.
In contrast to that, a process of regenerating a whole plant from plant cells or tissue, which takes advantages of the totipotency of many plant cells, comprises a series of important events and phases, such as the formation of shoot and then root meristems, the coordinated division, expansion and differentiation of cells, which require the careful selection of the appropriate working conditions, e.
Epigenetic reprogramming is an indispensable process in the establishment of totipotency after fertilization, and it is known to occur abruptly in early stages of embryo development (Reik et al.
Changes in the final balance of the salt concentration in the nutritional medium, particularly nitrogen-containing media, can cause modifications in the rate of growth and development of plants and affect the morphology and cell totipotency (ARAUJO et al.
The discovery of role of phytohormones such as Kinetin by Skoog [10], and demonstration of totipotency of plant cells by Steward, et al.
I explore the following proffered arguments for (ii): (a) indivisibility is a necessary condition of individuality, Co) nonidentity of an embryo with successor twins impugns the embryo's individuality, and (c) totipotency of an embryo's constituents is inconsistent with the embryo's being a human individual.
However, a potential ethical problem looms if the technique returned the cells beyond pluripotency to totipotency.
And the totipotency of the cells correlatively suggests--because they can each produce a whole--that they are more wholes than they are parts-of-a-whole.
Assessment of the developmental totipotency of neural cells in the cerebral cortex of mouse embryo by nuclear transfer.
Let me begin by acknowledging that Johnson is correct in noting that I mistakenly attribute totipotency to the preimplantation embryo as a whole.
