Última Change in root apical protein and peroxidase activity in response to aluminum in tolerant and sensitive maize inbred lines Braz. J. Plant Physiol. Souza,Isabel Regina Prazeres de; Alves,Vera Maria Carvalho; Parentoni,Sidney Netto; Oliveira,Antônio Carlos de; Teixeira,Flávia França; MacAdam,Jennifer Wilson; Purcino,Antônio Álvaro Corsetii. The effects of a short-term (80 min) exposure to 222 µM aluminum (Al) on the protein content and expression and on peroxidase activity and isoenzymes in the primary root of maize were evaluated. Two inbred lines differing in their level of tolerance to Al were used: Cateto 237 (tolerant) and L36 (sensitive). The apical 20 mm of the primary root was divided into 2-mm-long segments that were analyzed for total protein content and peroxidase activity. These results demonstrate that the total protein content along the root apex was not affected by Al in the tolerant inbred line, but decreased in the sensitive line. In the apical 2 mm of the root of the sensitive line, the expression of low molecular weight proteins (43 kDa or smaller) was decreased. Expression...
