Aluminium-induced ion transport in Arabidopsis: the relationship between Al tolerance and root ion flux.

Abstract excerpt

Aluminium (Al) rhizotoxicity coincides with low pH; however, it is unclear whether plant tolerance to these two factors is controlled by the same mechanism. To address this question, the Al-resistant alr104 mutant, two Al-sensitive mutants (als3 and als5), and wild-type Arabidopsis thaliana were compared in long-term exposure (solution culture) and in short-term exposure experiments (H(+) and K(+) fluxes,...
