  • Title: Polyamine distribution among maize embryonic tissues and its relation to seed germination.
    Author: Sepúlveda G, Sánchez de Jiménez E.
    Journal: Biochem Biophys Res Commun; 1988 Jun 16; 153(2):881-7. PubMed ID: 3382409.
    Abstract:
    Polyamines are known to participate in the control of cell division. In the present report, the levels and distribution of polyamines in the embryonic tissues of maize seeds were studied to relate them to the reinitiation of cell division during seed germination. Results indicate higher contents of polyamines in scutellum than in axis tissues of dry seeds. After germination, larger increments of the three polyamines were obtained in axes, rather than in scutella. Seeds of low viability did not show putrescine increments after germination. It is suggested that spermidine and spermine are directly related to the germination process.
