Looking at the present to gain knowledge on the past: what might be the primeval function of the phytochelatin synthase enzyme?

The phytochelatin synthase (PCS) enzyme is constitutively expressed in the majority of plants, other eukaryotes and certain cyanobacteria. In the presence of metal(loid)s (i.e., Cd, Pb, Hg, As; excess Cu and Zn) eukaryotic PCS is activated and produces the so-called phytochelatins, able ...

Phytochelatin synthase 1 regulates iron homeostasis in Arabidopsis thaliana

Phytochelatin synthases (PCS, EC 2.3.2.15) are cytosolic enzymes, constitutively expressed in the genome of different organisms including Schizosaccharomyces pombe (1), Caenorhabditis elegans (2,3), algae and plants (4). PCS have been explicitly studied with respect to their role and mechanism of ...

The symbiosis between Nicotiana tabacum and the endomycorrhizal fungus Funneliformis mosseae increases the plant glutathione level and decreases leaf cadmium and root arsenic contents

Over time, anthropogenic activities have led to severe cadmium (Cd) and arsenic (As) pollution in several environments. Plants inhabiting metal(loid)-contaminated areas should be able to sequester and detoxify these toxic elements as soon as they enter roots and leaves.We postulated h...

Phytoplasma infection in tomato is associated with re-organization of plasma membrane, ER stacks, and actin filaments in sieve elements

Phytoplasmas, biotrophic wall-less prokaryotes, only reside in sieve elements of their host plants. The essentials of the intimate interaction between phytoplasmas and their hosts are poorly understood, which calls for research on potential ultrastructural modifications. We investigated modifications of&#x...
