Abstract

Arabinogalactan proteins (AGP) are a class of cell surface plant peptidoglycans which have been implicated in root elongation and signal transduction pathways. Aluminum promotes the elongation of tea (Camellia sinensis L. ) roots. In this study the possible involvement of AGP in regulation of auxin, Gibberellin, and callose contents after exposure of Tea seedlings to 400 μ M Al was evaluated. The results show that the Al-induced elongation of tea roots was accompanied by significant increase of the AGP. Maximum contents of endogenous GA3, 270% of the control group were detected after 6 hrs. of the Al treatment. The content of IAA, rapidly (6 hrs. of the treatment) and remarkably declined due to Al to 50% of the control. In addition Al exposure for 6 and 24h periods decreased the callose content of Tea seedlings by 20% and 50% of that of the control cells, respectively. However, Al treatment for 6 hrs. increased the gene expression (167% of the control), and the activity of β-1, 3-glucanase (150% of the control). The findings suggest a cross-talk between AGP, callose, and the two main growth hormones auxin and Gibberellin in Tea seedling which was started by Al exposure and resulted in elongation of the roots.
