Quiescence and Dormancy in Somatic Embryos
1991Certain organisms avoid stress by entering a state of deep rest or dormancy; an adaptive mechanism that allows colonization of otherwise unfavorable environments. During dormancy, need for nutrients is greatly reduced as is sensitivity to environmental changes, thereby ensuring survival through hostile periods, such as dry or cold seasons. The adaptive

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.

Anatomy of Somatic Embryos from Maize Embryo Cultures
Botanical Gazette, 1986Putative somatic embryos of maize (Zea mays L.) that developed directly from the scutellum of immature zygotic embryos in agar culture were investigated in thin sections and by scanning electron microscopy to confirm the mode of regeneration. After 4-6 days in culture, a row of similar-sized swellings appeared on each zygotic embryo just above the ...

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.

THE UTILISATION OF AN EMBRYO BREEDER TECHNIQUE FOR MATURATION OF SOMATIC EMBRYOS
Acta Horticulturae, 1998The formation of embryos from somatic tissue may require several transfers to different media before ripe embryos can be harvested. In a semiopen system, where fresh medium is delivered continuously to the cells through a semipermeable membrane, the problem of repeated transfer can be avoided or the number of transfers reduced.

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
