    Study of callus tissues from different parts ofNigella sativa (Ranunculaceae) (1980)
    Springer
    Cellular and molecular life sciences 36 (1980), S. 305-306 
    Details
    ISSN: 1420-9071
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Callus tissues were produced from leaf, stem and seed ofNigella sativa in modified Murashige and Skoog's medium. Depending on the origin of explants, the time of callus initiation and also the properties of the callus tissue were found to be different, especially regarding chromosome instability.

    Role of an acid phosphatase isoenzyme in callus tissue during cytodifferentiation (1984)
    Springer
    Theoretical and applied genetics 68 (1984), S. 285-287

    Notes: Summary Both histological and isoenzyme patterns of acid phosphatase were observed in callus tissue of Vigna unquiculate (L.) Walp. up to the tenth passage from its initiation. It was observed that when un-differentiated cells begin to transform into a differentiated condition in the form of tracheids, and xylem vessels, a new acid phosphatase band appears at the anionic end of the polyacrylamide gel. The transformation of living cells into a dead, empty tracheid during cellular differentiation and the biosynthesis of the acid phosphatase enzyme are functionally related to the autolysis of the cell contents and lignin synthesis.
