Somatic embryogenesis, the process in which embryos, similar in morphology to their zygotic counterparts, are induced to develop in culture from somatic cells, is a suitable model system for investigating the regulation of embryo development. Through this process, a large number of embryos at defined stages of development can easily be obtained ...

Embryogenesis in higher plants consists of two major phases, morphogenesis and maturation. Morphogenesis involves the establishment of the embryo's body plan, whereas maturation involves cell expansion and accumulation of storage macromolecules to prepare for desiccation, germination and early seedling growth.

Somatic Embryogenesis in Grapevine
2001Somatic embryogenesis has been defined as the initiation of embryos from plant somatic tissues closely resembling their zygotic counterparts (Ammirato, 1983). This morphologic event has been documented as occurring spontaneously in some plant species (Yarbrough, 1932; Taylor, 1967), however it is usually induced in tissue cultures, potentially from ...

Microspore Embryogenesis in Citrus
2021This chapter deals with microspore embryogenesis in Citrus. Microspore embryogenesis allows to induce immature gametes (microspores) and to deviate them, in this case, the male one, from the normal gametophytic developmental route in the direction of the sporophytic one, yielding homozygous organisms (embryos and plants).

Embryogenesis and Angiogenesis
1997This chapter provides an overview of embryogenesis and angiogenesis processes. During embryogenesis, the development of new microvessels from in situ differentiating endothelial cells is referred to as vasculogenesis, and subsequent sprouting from existing vessels is referred to as angiogenesis.

Publisher Summary This chapter focuses on the cestode gametogenesis and embryonic development up to the formation of the oncosphere. A common basic pattern of embryogenesis in pseudophyllideans and cyclophyllideans representing the main groups in Cestoda is discussed.

Publisher Summary This chapter presents a generalized view of some of the more regular features of insect development. Embryogenesis is the process by which a larva or a juvenile is built from a single egg. The fertilized egg divides to produce hundreds of cells that grow, move, and differentiate into all the organs and tissues required to form a ...

Epigenetic silencing in embryogenesis
Experimental Cell Research, 2005Transcription profiling of early embryos emphasizes that differential gene expression is a fundamental control mechanism of development. Precise regulatory mechanisms operate on a background of epigenetic changes in chromatin composition, modification, and architecture that are integral for the development of a pluripotent embryo into an adult.

The embryonic heart forms in anterior lateral splanchnic mesoderm and is derived from Mesp1-expressing progenitor cells. During embryonic folding, the earliest differentiating progenitor cells form the linear heart tube in the ventral midline. The heart tube extends in length and loops to the right as new myocardium is progressively added at the venous
