In crop plants, aluminum (Al) rhizotoxicity is a major problem worldwide; however, the cause of Al toxicity remains elusive. The effects of Al on the inositol 1,4,5-trisphosphate (Ins[1,4,5]P3)-mediated signal transduction pathway were investigated in wheat roots. Exogenously applied Al (50 [mu]M) rapidly inhibited root growth (<2 hr) but did not affect general root metabolism. An Ins(1,4,5)P3 transient was generated in root tips, either before or after exposure to Al for 1 hr, by treating the… CONTINUE READING
