Somatic embryos of daylily in space
Advances in Space Research, 1999Poor growth and nuclear abnormalities observable in some space-grown plants have been hypothesized as due to a combination of factors such as degree of development, the specific way the plants are grown and the way they experience multiple stresses, some of which are space-specific.

Automation of somatic embryo production
Plant Cell, Tissue and Organ Culture, 2001Automation could enhance the use of somatic embryogenesis for micropropagation in two ways: as effective tools for research on somatic embryogenesis, and for improving the efficiency of embryo production by reducing labor costs. Processes expected to be automated for somatic embryo production are: (1) evaluation of embryogenic cultures, (2) embryo ...

Epigenetic modifications and miRNAs determine the transition of somatic cells into somatic embryos
Plant Cell Reports, 2023This review discusses the epigenetic changes during somatic embryo (SE) development, highlights the genes and miRNAs involved in the transition of somatic cells into SEs as a result of epigenetic changes, and draws insights on biotechnological opportunities to study SE development.

Cryopreservation of Somatic Embryos
1995Since somatic embryos (SEs) can be produced in large numbers in bioreactors (Denchev et al. 1992), and are being employed for mass micropropagation (Merkle et al. 1991; Bajaj 1991a), genetic transformation (Ellis 1993), and for the production of synthetic seed (Redenbaugh et al.

Micropropagation Through Somatic Embryos
1995Commercial micropropagation is a challenging plant biotechnology industry that offers new methods of plant production. A micropropagation system exploits the morphogenic potential of existing growing points or meristems within the plant (Giles and Morgan 1987).

Immunolocalization of Proteins in Somatic Embryos
2008Plant embryogenesis requires a tight balance between cell proliferation and differentiation. In animals, embryogenesis is dependent on cell migrations, which is in contrast to plant embryogenesis where the rigid cell wall precludes migration. Therefore, plants have to position cells correctly by defining the direction of the division plane during ...

Somatic embryo production in bioreactors
Journal of Biotechnology, 1992Within the past ten years much progress has been made with various aspects of plant tissue culture and the outlook for in vitro genetic manipulation is considerably more encouraging. One of the more significant developments has been the demonstration of plant regeneration by somatic organogenesis and embryogenesis from various explants (Williams and ...

Somatic embryogenesis in soybean via somatic embryo cycling
In Vitro Cellular & Developmental Biology - Plant, 1992The objectives of the present research were: a) to develop an efficient soybean embryogenic regeneration system characterized by a high frequency of explant response and a large number of somatic embryos per explant; b) to evaluate the factors affecting somatic embryogenesis via somatic embryo cycling; and c) to identify the origin of somatic embryos ...

Inorganic Compounds that Aid in Obtaining Somatic Embryos
2022Somatic embryogenesis (SE) is a process that allows formation of embryos from somatic cells; this biological process has different stages that first require micropropagation and conditioning of explant, and then induction, multiplication, development, and germination of somatic embryos (SoE), to obtain seedlings that will be acclimatized and grown in a

Cryopreservation of zygotic embryo axes and somatic embryos of European chestnut.
Cryo letters, 2004This work describes experiments demonstrating the feasibility of long-term conservation of Castanea sativa germplasm through cryopreservation of embryonic axes or somatic embryo clumps. Between 93% and 100% of excised embryonic axes of recalcitrant chestnut seeds survived storage in liquid nitrogen (LN) following desiccation in a laminar flow cabinet ...
