Wheat root responses to aluminum toxicity in relation to cell wall composition and adsorption-desorption of aluminum by cell wall in root tips
|
Abstract:
Aluminum (Al) toxicity is an important factor determining the distribution of plant species and ecotypes in natural habitats and crop productivity in acid soils. Aluminum primarily affects root growth by interfering with processes critical for the regulation of growth in the root apex. Despite a large research effort in the last 30 years, the mechanism of Al-induced inhibition of root growth and the reasons for the spatial differences in Al sensitivity between apical root zones are still not clear. Over the...
