Culturing leaf protoplast-derived cells of the embryogenic alfalfa (Medicago sativa subsp. varia A2) genotype in the presence of low (1 μm) or high (10 μm) 2, 4-dichlorophenoxyacetic acid (2,4-D) concentrations results in different cell types. Cells exposed to high 2,4-D concentration remain small with dense cytoplasm and can develop into proembryogenic cell clusters, whereas protoplasts.

Here we try to summarise the present knowledge on the early induction phase of embryogenic competence of somatic plant cells including some of our recent results using alfalfa.

Ötvös K, Pasternak TP, Miskolczi P, Domoki M, Dorjgotov D, Szûcs A, Bottka S, Dudits D, Fehér A () Nitric oxide is required for, and promotes auxin-mediated activation of, cell division and embryogenic cell formation but does not influence cell cycle progression in alfalfa cell cultures.

Plants possess a unique class of CDKs (B-type CDKs) with preferential protein accumulation at G2/M-phases; however, their exact functions are still enigmatic. Here we describe the functional characterization of a bp promoter region of the alfalfa (Medicago sativa) CDKB2;1.

SERK (somatic embryogenesis receptor kinase) was originally identified as a gene that marks the embryonic competence in carrot cell culture (Schmidt et al., ).

Both reverse transcription (RT)-PCR and SERK promoter::luciferase analysis indicate that SERK is highly expressed in embryogenic cell cultures and transiently during somatic.

The embryogenic cells have also been reported to express a gene that encodes a cell surface-located receptor-like protein, but the target or the function of the protein is unknown.

Other studies have correlated embryogenic cells with the production of an arabinogalactan protein (for AGP, see Chapter 2), which can be localized in the cell wall.

In cultures of F. mandshurica, somatic embryos were produced mainly on browned explants. Therefore, we studied the mechanism of explant browning and its relationship with somatic embryogenesis (SE).

We used explants derived from F. mandshurica immature zygotic embryo cotyledons as by: 8. Histidine protein kinases are members of two-component signaling relays.

Two-component systems have been shown to be important in both cytokinin and ethylene signal transduction in plants. Histidine protein kinases and two-component systems are covered in another chapter of The Arabidopsis Book (Schaller et al., ).Cited by:   The molecular mechanisms underlying the initiation and maintenance of the embryonic pathway in plants are largely unknown.

To obtain more insight into these processes, we used subtractive hybridization to identify genes that are upregulated during the in vitro induction of embryo development from immature pollen grains of Brassica napus (microspore embryogenesis).Cited by: DcSERK1 (from Daucus carota) was the first family member to be isolated and is a marker for competence of cells to form somatic embryos (Schmidt et al., ).

The Arabidopsis ortholog of DcSERK1 (SERK1) also appears to enhance embryogenic competence in culture and is expressed in developing embryos and ovules (Hecht et al., ). However Cited by: Embryogenic callus formation is followed by the development of proembryogenic masses (PEMs) on the surface or within the callus mass, from which single cells or cell clusters develop into embryos (Halperin, ; Toonen et al., ).
