Plant embryogenesis

Plant embryogenesis is the process by which plant embryos form and develop. During embryogenesis the basic body plan of the plant is established, primary plant tissue types are differentiated, and food reserves are accumulated that will ultimately be used by the germinating seedling following a period of dormancy.

    Arabidopsis embryonic root development involves the formation of distinct cell types and tissues in a tightly regulated and thereby highly predictable spatio-temporal manner. A crosstalk between maternal and embryonic genes orchestrates division orientation and fate specification to control root development.

    Mothers and fathers contribute equally to the early embryonic transcriptome in plants, but the full extent of parental control of embryogenesis is unknown. Now it has been reported that expression of parental alleles can vary across cell types.

    Major life cycle transitions happen after changes in stem cells trigger new developmental programs. In moss, expression of the homeobox transcription factor BELL1 is sufficient to induce sporophyte stem cells from the gametophyte phase, without having to go through fertilization.

    Plant researchers have speculated about the need for mechanisms to lock-down cell fate in late development. In PRC2 mutants, specialized, endoreplicated root hair cells differentiate normally but later revert to an embryo-like state.
