Figure 1 Plant embryos. Our diet includes many different plant embryos (e.g., beans or nuts), and seeds (e.g., maize kernel or rice grain) that contain an embryo. Current Biology 2017 27, R870-R873DOI: (10.1016/j.cub.2017.05.026) Copyright © 2017 Elsevier Ltd Terms and Conditions

Figure 2 Origins, development and diversity of plant embryos. (A) Various cells (grey cell in dashed red box) can generate plant embryos. Zygotic embryos form from the egg cell but microspores, somatic cells and in vitro-generated callus cells can also start embryogenesis. (B) Two sequential processes define plant embryogenesis: its initiation from a non-embryonic precursor, followed by the development of a multi-cellular embryo. (C) Embryos in land plants are diverse. While the multicellular bryophyte embryo generates single-celled spores, multicellular bodies with different organs (color legend below) are formed in, for example, gymnosperms, monocots and dicots.
