Mutants for Biochemical and Molecular Insights into Embryogenesis in Plants

Abstract

Despite the advancements that have been made in understanding the intricate mechanisms of embryogenesis, a

lot remains elusive. However, the understanding of the mutants of different stages of embryo development viz. tsIl,

gnom, mickey, lee etc. have opened up new vistas towards gaining insights into their biochemical and molecular basis

of embryogenesis. Today, studies on mutants have not only played a major role in the easier manipulation of PGRs

ill vitro but have also led to the important discoveries of genes that are involved in the process of embryo pattern

formation and in elucidating the underlying genetic, molecular and physiological mechanisms of inducing polarity,

cotyledon initiation and pro-vascular tissue differentiation. The present review deals with the different mutants and

the role they have played in the understanding of molecular and biochemical insights of somatic embryogenesis.
