Somatic Embryogenesis in Plants
2004Somatic embryogenesis refers to the remarkable ability of nonzygotic plant cells (including haploid cells) to develop through characteristic embryological stages into an embryo capable of developing into a mature plant. Somatic embryogenesis is an expression of totipotency and the associated differential gene expression. Somatic embryos may be produced

Somatic Embryogenesis in the Cycadales
1995The cycads (Fig. 1) constitute remnant species of an ancient class of gymnosperms, the cycadophytes, that evolved from the free-sporing progymnosperms, which also gave rise to the coniferophytes. According to Gifford & Foster (1989), the cycadophytes have included 3 orders of plants, the extinct Cycadeoidales and Pteridospermales (seed ferns), that are

Somatic embryogenesis in Salix [PDF]
, 1995 Salix is a diverse genus of several hundred species, some being tall trees, others creeping brushwood while most are medium-sized bushes. They are popularly known as willows and in some cases as sallows and osiers. Almost all are dioecious, with the numerous, insect-pollinated flowers in cylindrical inflorescences, catkins.

Somatic embryogenesis inAesculus
In Vitro Cellular & Developmental Biology - Plant, 1996Somatic embryogenesis was observed with explants taken from four types ofAesculus tissue: (a) shoots of 4-wk-oldin vitro germinated excised embryos (seed fromA.×arnoldiana), (b) roots of 4-wk-oldin vitro germinated excised embryos (seed fromA.×arnoldiana), (c) shoots from newly forced 3-yr-old seedlings (A.

Somatic Embryogenesis Protocol: Citrus
2005somatic embryo regeneration have involved the culture of isolated nucelli, nucellar embryos, or whole fertilized or unfertilized ovules. As regenerated somatic embryos usually originate fromnucellar tissues, they have a genetic makeup that is identical to that of the plant source, excluding mutational events.

Somatic Embryogenesis in Dioscorea
Journal of Plant Physiology, 1988Summary Cells of a proliferating callus tissue derived from the dormant zygotic embryo of white edible yam, Dioscorea rotundata, formed somatic embryos on MS medium supplemented with 6x10-6M NAA plus 1g1-1 casein hydrolysate. Embryogenic competence was dependent on light and the presence of casein hydrolysate in the NAA-containing induction medium.

Somatic embryogenesis in orchardgrass
1991If there exists a model monocotyledonous species with regard to somatic embryogenesis, then orchardgrass (Dactylis glomerata L.) must surely be nominated. As described by Conger and colleagues at the University of Tennessee [1], one is able to induce an embryogenic response from young leaf bases such that an abundance of mature, convertible somatic ...

Histology of Somatic Embryogenesis
1992Asexual multiplication is a unique process by which plants give rise to new individuals identical to the parent plant. This potential can be directly extended by microcutting, an in vitro vegetative propagation technique. Cell totipotency is also specific to the plant kingdom and expressed in in vitro cultures by the ability to regenerate embryos from ...

Anatomy of Somatic Embryogenesis
1995The regeneration of plants in tissue culture is generally possible through two morphological and anatomic different pathways: (1) somatic embryogenesis and (2) shoot/root organogenesis involving adventitious shoot bud development (see Reinert et al. 1977).

Micropropagation and somatic embryogenesis
1993Due both to ease of production and handling as well as the potential for specialized treatment, seed is the preferred vehicle for the propagation and cultivation of most agronomic and forest tree species (Gray, 1990). However, a glance at the list of the world’s top crops (Witt, 1985) reveals that 10 of the 30 crops with an annual production of between
