Jelena Pavlović,Jelena Samardzic,Vuk Maksimović,Gordana Timotijević,Nenad Stevic,Kristian Holst Laursen,Thomas H. Hansen,Søren Husted,Jan K. Schjoerring,Yongchao Liang,Miroslav Nikolic +10 more
TL;DR: Investigation of how Si ameliorates Fe deficiency in cucumber with focus on the storage and utilization of Fe in the root apoplast indicates that Si-mediated alleviation of Fe deficiency includes an increase of the apoplastic Fe pool in roots and an enhancement of Fe acquisition.
Journal ArticleDOI
Simultaneous iron, zinc, sulfur and phosphorus speciation analysis of barley grain tissues using SEC-ICP-MS and IP-ICP-MS
TL;DR: Fe and Zn have a different speciation in cereal grain tissues; Zn appears to be mainly bound to peptides, while Fe is mainly associated with phytic acid.
Journal ArticleDOI
The molecular-physiological functions of mineral macronutrients and their consequences for deficiency symptoms in plants.
TL;DR: A proper interpretation of visual deficiency symptoms will support the potential for sustainable crop intensification through development of new technologies that facilitate automatized management practices based on imaging technologies, remote sensing and in-field sensors, thereby providing the basis for timely application of nutrients via smart and more efficient fertilization.
Journal ArticleDOI
Effect of foliar application of selenium on its uptake and speciation in carrot.
Emese Kápolna,Peter René Hillestrøm,Kristian Holst Laursen,Søren Husted,Erik Huusfeldt Larsen +4 more
TL;DR: In this article, anion and cation exchange HPLC were tailored to and applied for the separation of selenium species in proteolytic extracts of the biological tissues using detection by ICP-MS or ESI-MS/MS.
Journal ArticleDOI
Micro-scaled high-throughput digestion of plant tissue samples for multi-elemental analysis.
Thomas H. Hansen,Kristian Holst Laursen,Daniel P. Persson,Pai Pedas,Søren Husted,Jan K. Schjoerring +5 more
TL;DR: A high-throughput micro-scaled microwave digestion procedure has been developed which enables digestion of small quantities of plant samples for subsequent elemental profiling by ICP-spectrometry, which constitutes a valuable tool for screening of mutants and transformants.
