Question

Plant regeneration pathways from somatic embryo biology discussion

Answer 1

Answer:

Explanation:

Somatic embryogenesis is the process in which a single cell or a small group of cells follow a developmental pathway that leads to reproducible regeneration of non-zygotic embryos which are capable of producing a complete plant. These non-zygotic embryos may originate directly from other organs or parthenogenetic embryos (without fertiliza­tion) or androgenetic embryos (from the male gametophyte).

In general somatic embryos are those which are formed from the somatic tissue in cultural i.e., in vitro condition. Embryos formed in cultures have been variously designated as accessory embryos, adventive embryos, embryoids and supernumerary embryos.

Answer 2

What is somatic embryo regeneration?

Somatic embryo are non zygotic embryo like structures that develop in vitro cultures from somatic cells, this process is known as somatic embryo regeneration.

Additional related Points:-

➲ It is also known as embroyoids.

➲ The medium having ammonum hirate and auxin (2,4-D) favour induces their differentiation.

➲ Mature somatic embryos germinate to yield complete plantlets.
