An atlas of plant selenium metabolism

Jeroen van der Woude, Mark G. M. Aarts, Michela Schiavon, Antony van der Ent

Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth-promoting or negative effects, depending on the …

Agromining of Nickel: Finally Becoming a Reality at Commercial Scale

Antony van der Ent, Mark G. M. Aarts, Jean Louis Morel, Rufus L. Chaney et autres

Initially proposed over 40 years ago, the biotechnology of agromining has had a long and tortuous gestational process on the way to becoming a proven commercial reality. The field has been marred by claims for unrealistic yields made by startup companies. Nevertheless, …

Fluoride detoxification in tea plants depends on aluminum and localization in the epidermis

Chenyu Zhang, Paula Pongrac, Vogel-Mikus Katarina, Alessandra Gianoncelli et autres

Tea (Camellia sinensis) is a hyperaccumulator of both aluminum (Al) and fluorine (F). While the formation of Al-F complexes has been proposed as a key mechanism for F detoxification and accumulation in tea, excessive Al and especially fluoride (F-) pose health risks …

Uncovering adaptation with a new Arabidopsis thaliana multiparent intercross population

Célia Neto, Tom P J M Theeuwen, Pádraic J. Flood, Paula Unger Avila et autres

Understanding the molecular basis of adaptation and the genetic architecture of complex traits are longstanding goals in biology. One problem impeding this understanding is the complexity of continental populations, with their complicated demographic histories, gene flow and secondary contact. In contrast, island …

Engineering of nicotianamine synthesis enhances cadmium mobility in plants and results in higher seed cadmium concentrations

Fabian Hollmann, Michael Weber, Mark G. M. Aarts, Stephan Clemens

Efficient biofortification, i.e., the enrichment of edible plant organs with micronutrients available for human consumption, is pursued through breeding and genetic engineering approaches. Enriching for iron (Fe) and zinc (Zn), two of the most critical trace elements, in cereal grains can be …

Cadmium localization and chemical environment in a cadmium bioindicator Gomphrena claussenii

Paula Pongrac, Mina T. Villafort Carvalho, Tânia S. Serra, Hiram Castillo Michel et autres

Motivacija za to magistrsko delo je bilo avtoričino iskanje podobe; prav določene podobe, izgubljene v najglobljih predelih našega uma. Iskanje podobe, ki je nikoli nismo videli ali doživeli; podobe, ki je še nihče nikoli ni videl, ter ob tem izzvati čutila in …

Cadmium associates with oxalate in calcium oxalate crystals and competes with calcium for translocation to stems in the cadmium bioindicator Gomphrena claussenii

Paula Pongrac, Tânia S. Serra, Hiram Castillo Michel, Vogel-Mikus Katarina et autres

Cadmium (Cd) was shown to co-localise with calcium (Ca) in oxalate crystals in the stems and leaves of Cd tolerant Gomphrena claussenii, but Cd binding remained unresolved. Using synchrotron radiation X-ray absorption near edge spectroscopy we demonstrate that in oxalate crystals of …
