The use of the aquatic moss Fontinalis antipyretica L. ex Hedw. as a bioindicator for heavy metals: 3. Cd2+ accumulation capacities and biochemical stress response of two Fontinalis species.
Corinna Bleuel,Dirk Wesenberg,K. Sutter,Jürgen Miersch,Bianca Braha,Felix Bärlocher,Gerd-J. Krauss +6 more
TL;DR: Both Fontinalis species appear to be suitable for heavy metal biomonitoring in aquatic habitats because of differences in leaflet surface and cell wall composition.

Rapid and simple UPLC-MS/MS method for precise phytochelatin quantification in alga extracts.
TL;DR: For the first time reproducible quantification of six thiol peptides in crude extracts of Clamydomonas reinhardtii was possible, and relative detection limits in the nanomolar range in microliter sample volumes were achieved.

Physiological characterization of cadmium-exposed Chlamydomonas reinhardtii
TL;DR: It is hypothesize that CysPC may prevent the synthesis of canonical PCs by blocking the binding pocket, and possible physiological reasons for the high abundance of CYSPC compared with their canonic precursors are discussed.

Pteris vittata – Revisited: Uptake of As and its speciation, impact of P, role of phytochelatins and S
Doris Vetterlein,Doris Vetterlein,Dirk Wesenberg,Petra Nathan,Anja Bräutigam,Angelika Schierhorn,Jürgen Mattusch,Reinhold Jahn +7 more
TL;DR: An increase of As concentration with increasing soil solution As concentrations, but P application had no impact, although plant P concentrations responded to different rates of P supply, indicates the need for a detailed investigation on sulphur nutritional status and As metabolism in P. vittata.

Analytical approach for characterization of cadmium-induced thiol peptides—a case study using Chlamydomonas reinhardtii
TL;DR: Results showed a progressive decline of the glutathione content, accompanied by an induction of phytochelatins in Chlamydomonas reinhardtii, and thiol peptides of higher molecular masses suggesting PCn with n > 5 could be identified as intermolecular oxidation products of smaller PCs.
