In order to study the mechanism of aluminium(Al)-induced inhibition of root elongation, DNA was purified from Alaska pea seedlings and some physical properties and template activity supported by E. coli RNA polymerase were measured in the presence of Al. The absorption spectrum of the DNA did not shift, indicating that Al might bind to the DNA phosphate. While the Tm (melting temperature) of DNA was not affected by Al, the rate of hyperchromicity was reduced with increasing concentrations of Al. The template activity of the DNA was clearly suppressed by the amount of Al which was needed for the reduction of hyperchromicity.
