Somatic Embryogenesis in Some Cactus and Agave Species

Abstract

Somatic embryogenesis is an asexual form of plant propagation in nature that mimics many of the
events of sexual reproduction. Also, this process may be reproduced artificially by the manipulation
of tissues and cells in vitro. Some of the most important factors for a successful plant regeneration
are the culture medium and environmental incubation conditions. In vitro somatic embryogenesis is
an important prerequisite for the use of many biotechnological tools for genetic improvement, as
well as for mass propagation. In this paper the somatic embryogenesis of several agaves and cacti
is reviewed.
