Somatic Embryogenesis in Herbaceous Monocots,e zygote following the fertilization of the egg cell by one of the male gametes. Gene recombination during the formation, as well as the fusion, of the gametes plays a critical role in the evolution of the angiosperms. During its development the embryo is nourished by the endosperm, which itself is

Asexual Embryogenesis in Vascular Plants in Nature,ision is usually absent, and thus chromosomes do not segregate. Agamospermy includes “adventitious embryony” and “gametophytic apomixis” and results in the formation of one or more asexual embryos along with or without the sexually produced zygotic embryo leading to “polyembryony”. Flowers designed

Zygotic Embryogenesis in Gymnosperms and Angiosperms,me biochemical and physiological transformations as other living cells. Our present ontogenetic concepts of embryogenesis have been given a new twist by the discovery that somatic cells of many phanerogams and pollen grains of certain angiosperms can display with a high degree of fidelity an embryog

Structural and Developmental Patterns in Somatic Embryogenesis, a synthesis of the information available concerning the structural and developmental patterns observed during somatic embryogenesis. Only selected, well-characterized systems will be discussed. Some speculations, hypotheses, and questions are provided to stimulate further experimentation in this ar

Somatic Embryogenesis in Herbaceous Dicots,is only a modification of the process of embryo induction and development. With this view, embryogenesis could be considered to be the result of a sequence of competing organogenic events. The idea that the developmental pathways of organogenesis and embryogenesis are distinct has also been challeng
