Ontogeny of Grape Somatic Embryos [PDF]

open access: yesHortScience, 1996
The development of grape somatic embryos (Vitis vinifera cv. Thompson Seedless) was studied using high-resolution light microscopy and scanning electron microscopy. Somatic embryos develop either from discrete embryogenic cell clusters (indirect somatic embryogenesis) or from previously formed somatic embryos (direct somatic embryogenesis).

Testing of Algerian fir zygotic and somatic embryos on defence reactions in vitro

open access: yesPlant, Soil and Environment, 2012
Defence reactions of desiccated cotyledonary somatic embryos and mature zygotic embryos of Abies numidica were tested by dual cultures with tester, fungus Phaeolus schweinitzii. Both types of embryos expressed defence reactions.

Single-base resolution methylomes of somatic embryogenesis in Theobroma cacao L. reveal epigenome modifications associated with somatic embryo abnormalities

open access: yesScientific Reports, 2022
Propagation by somatic embryogenesis in Theobroma cacao has some issues to be solved, as many morphologically abnormal somatic embryos that do not germinate into plants are frequently observed, thus hampering plant production on a commercial scale.

Manifestation of embryogenic potential in culture of zygotic embryos of Quercus robur L.

open access: yesActa Societatis Botanicorum Poloniae, 2014
For the initiation of somatic embryogenesis early cotyledonary stage of zygotic embryo explants (from 15th July until late August) was suitable. The highest frequency of differentiation of somatic embryos was obtained on cotyledons of zygotic embryos ...

The relationship between cell size and cell fate in Volvox carteri [PDF]

open access: yes, 1993
In Volvox carteri development, visibly asymmetric cleavage divisions set apart large embryonic cells that will become asexual reproductive cells (gonidia) from smaller cells that will produce terminally differentiated somatic cells. Three mechanisms have
