Abstract excerpt
Root elongation is a primary target of Al toxicity in plants. The objective of this study was to see whether Al-induced disturbance of ion homeostasis is related to the inhibition of root elongation. For this purpose, root growth rate, free cytoplasmic calcium (Ca²+) and vacuolar content of phosphate (P(i)), potassium (K+), nitrate (NO₃⁻) and malate, as well as malate and citrate exudation and nitrate reductase...
