Abstract

The quantitative changes in proteins and peroxidases associated with A1 toxicity were investigated in various root-cell fractions of upland rice cultivars that differ in A1 tolerance. The impact of A1 on growth of the A1-sensitive rice cultivar IR45 was related to a marked reduction of protein content in cytoplasm and an increase in the covalently-bound cell wall fractions. Regardless of cellular fractions, A1 also induced peroxidase activities in IR45 indicating a root-damage response to A1. In contrast, the A1 tolerant rice cultivar BG35 maintained the content of cellular proteins and enzyme activities under A1 stress.
