AB  - Both calcium ion (Ca(2+)) and salicylic acid (SA) influence various stress 
      responses in plants. In acidic soils, aluminum (Al) toxicity adversely affects 
      crop yield. In this study, we determined the influences of Ca(2+) and SA on root 
      elongation, Al accumulation, and citrate secretion in soybean plant. We also 
      investigated the activity of antioxidative enzymes in Al-exposed soybean roots. 
      Root elongation was severally inhibited when the roots were exposed to 30 muM Al. 
      The Al-induced inhibition of root elongation was ameliorated by Ca(2+) and SA but 
      aggravated by Ca(2+) channel inhibitor (VP), CaM antagonists (TFP), Ca(2+) 
      chelator (EGTA), and SA biosynthesis inhibitor (PAC). Furthermore, 1.0 mM CaCl2 
      and 10 muM SA reduced the accumulation of Al in roots, but their inhibitors 
      stimulated the accumulation of Al in roots. Citrate secretion from these roots 
      increased with the addition of either 1.0 mM CaCl2 or 10 muM SA but did not 
      increase significantly when treated with higher Ca(2+) concentration. Enzymatic 
      analysis showed that Ca(2+) and SA stimulated the activities of superoxidase 
      (SOD), peroxidase (POD), and ascorbate peroxidase (APX) in Al-treated roots. In 
      addition, SA restored the inhibition of Ca(2+) inhibitors on root elongation and 
      Al content. Thus, both Ca(2+) and SA contribute to Al tolerance in soybean. 
      Furthermore, Ca(2+) supplements rapidly increased Al-induced accumulation of 
      free-SA or conjugated SA (SAG), while Ca(2+) inhibitors delayed the accumulation 
      of SA for more than 8 h. Within 4 h of treatment, SA increased cytosolic Ca(2+) 
      concentration in Al-treated roots, and upregulated the expression of four genes 
      that possibly encode calmodulin-like (CML) proteins. These findings indicate that 
      SA is involved in Ca(2+)-mediated signal transduction pathways in Al tolerance.
