Abstract:
... Programmed cell death (PCD) induced by aluminum (Al) is considered an important reason of Al phytotoxicity. However, the underlying mechanism of how Al induces PCD remains largely unknown in plants. The roles of glucose-6-phosphate dehydrogenase (G6PDH) and abscisic acid (ABA) in regulating Al-induced PCD were investigated in soybean roots. Al treatment increased G6PDH activity, while inhibition o ...

Abstract:
... Aluminium (Al) stress is a major limiting factor for worldwide crop production in acid soils. In Arabidopsis thaliana, the TAA1‐dependent local auxin biosynthesis in the root‐apex transition zone (TZ), the major perception site for Al toxicity, is crucial for the Al‐induced root‐growth inhibition, while the mechanism underlying Al‐regulated auxin accumulation in the TZ is not fully understood. In ...
