The embryogenic cell suspension was obtained from immature embryos of <em>Lolium multiflorum</em> through a callus culture. Somatic embryogenesis was induced by addition of 2,4-D, dicamba and picloram in 0,5 mg/l concentrations in MS liquid nutrient medium. It was shown that somatic embryos arised from single cells. In globular embryoids, the meristematic cells are characterized by the presence of phytoferritin inclusions in the leucoplasts.

Gentiana Kurroo

Two-dimensional gel electrophoresis was used to compare protein expression profiles between various stages of <em>Gentiana kurroo</em> Royle somatic embryos. Seven distinct stages (I–VII) were pointed out and measured from long-term embryogenic cell suspension. Isoelectric focusing was done in the pH intervals 3–10, and the second dimension was carried out with 13% SDS-polyacrylamide gel electrophoresis. Dependent on the stage from about 400 (stage IV) to more than 700 (stage II) protein spots were totally detected. The molecular weight of abundant proteins range from 12 to 70 kDa, however, majority of proteins were located between 20–49 kDa spots on the gels. The highest difference in the number of spots appeared in the case of globular embryo (stage I) and elongated cotyledonary stage (stage VII) with differences being about 130 spots. The relevance of embryogenic cell suspension choice for proteomic analysis as well as expediency of the increasing number of particular embryo stages is discussed.
