In higher plants the L-galactose pathway represents the major route for ascorbate biosynthesis. The first committed step of this pathway is catalysed by the enzyme GDP-L-galactose phosphorylase and is encoded by two paralogs in Arabidopsis – VITAMI

Low bioavailable concentrations of the micronutrient zinc (Zn) limit agricultural production on 40% of cultivated land. Here, we demonstrate that plant acclimation to Zn deficiency involves systemic regulation. Physiological Zn deficiency of Arabidop

The tripeptide glutathione (GSH) is an important metabolite with a broad spectrum of functions, and its homeostasis is essential to maintain cellular redox poise and effective responses to stress in plants. In Arabidopsis GSH is synthesised in two su

In Arabidopsis thaliana , biosynthesis of the essential thiol antioxidant, glutathione (GSH), is plastid-regulated, but many GSH functions, including heavy metal detoxification and plant defense activation, depend on cytosolic GSH. This finding sugge

HMA P‐type ATPases are the major mechanism for root‐to‐shoot Cd translocation in Arabidopsis thaliana

Autor: Christopher S. Cobbett, Chong Kum Edwin Wong

Publikováno v: New Phytologist. 181:71-78

The Zn/Cd-transporting ATPases, HMA2 and HMA4, essential for root-to-shoot Zn translocation, are also able to transport Cd. Phytochelatins (PCs) are a major mechanism of Cd detoxification through the sequestration of PC-Cd complexes in vacuoles. The
