Auxin and root initiation in somatic embryos of Arabidopsis
Plant Cell Reports, 2006Somatic embryos of Arabidopsis thaliana can be produced from explants of developing zygotic embryos. Cultivation of explants on maturation medium results in development of three main classes of regenerative structures: adventitious shoots, fused shoots, and complete somatic embryos. The ontogeny and anatomy of these structures was examined using serial

Gene Expression in Somatic Embryos
1995The developmental biology of somatic embryos is similar in many respects to that of plant zygotic embryos. For that reason, the analysis of gene expression during somatic embryogenesis has been viewed as an alternative means to investigate the genetic control of zygotic embryo development, which can be technically difficult.

Static suspension culture of carrot somatic embryos
Journal of Bioscience and Bioengineering, 2005Three culture methods of carrot somatic embryos were compared: conventional shake flask culture, static suspension culture using Erlenmeyer flasks, and static suspension culture using petri dishes. Compared with the former two cultures, the last one resulted in an enhanced ratio of torpedo-shaped embryos and suppressed cotyledonary-stage embryo ...

Morphological kinetics and distribution in somatic embryo cultures
Biotechnology and Bioengineering, 1994AbstractThe environmental effects on developing somatic embryos should be characterized not only by the growth based on biomass, but also by the morphological properties and size. We have previously developed a discrete classifier to separate developing embryos into distinct morphological classes.

Genetic Transformation of Somatic Embryos
1995Although DNA can be introduced into virtually any plant cell, several biological constraints still exist for the regeneration of transformed plants. These biological constraints are linked to the ability of an individual cell to respond to both the introduced DNA and to a regeneration stimulus.

Classification of plant somatic embryos by computer vision
Biotechnology and Bioengineering, 1993AbstractThis article deals with the automation of the process of somatic embryogenesis for the propagation of plants. An important problem is the monitoring of the embryo production process in order to decide the time to start harvesting embryos for further processing.

Summary Converted somatic embryos of Corydalis yanhusuo showed direct development of somatic embryos in the region at the junction of cotyledonary leaf and root when cultured on Murashige and Skoog (MS) basal medium supplemented with 0-16 mg/L abscisic acid (ABA) and with 2 mg/L being optimum for further development.

On the Segregation of the Germ and Somatic Cell Lines in the Embryo
Differentiation, 1982In this paper we argue that the mechanisms underlying the segregation of the somatic and germ cell lines are basically similar. The interaction of the genome with specific cytoplasmic factors is responsible for the restriction of their developmental potencies in the somatic cell lines, and for the prevention of such a restriction in the germ cell line.

Orchid protocorm‐like bodies are somatic embryos
American Journal of Botany, 2013• Premise of the study: Protocorm‐like bodies (PLBs) of orchids are important in orchid micropropagation and outwardly resemble somatic embryos in form and development. To determine whether PLBs are truly embryogenetic, we compared PLBs with somatic embryos and zygotic embryos to determine whether they had similar surface molecules and whether ...

Somatic embryos from callus of Sequoia sempervirens
Plant Cell Reports, 1988Compact calli with a potential for somatic embryogenesis were obtained from complete or split mature zygotic embryos or from cotyledons and hypocotyls of in vitro grown seedlings of Sequoia sempervirens. Somatic embryos which showed a typical bipolar structure, were formed together with adventitious buds.
