Vacuolar compartmentalization or cell wall binding in leaves could play a major role in hyperaccumulation of heavy metals. However, little is known about the physiology of intracellular cadmium (Cd) sequestration in plants. We investigated the role of the leaf cells in allocating metal in hyperaccumulating plants by measuring short-term (109)Cd and (65)Zn uptake in mesophyll protoplasts of Thla...

In the Upper Midwest, corn (Zea mays L.) and soybean (Glycine max [L.] Merr.) dominate landscape, but only for six to seven months of year. Thus, opportunities exist establish crops that can utilize remainder growing season contribute overall farm profitability. One species interest is pennycress (Thlaspi arvense L.), a lack established agronomic best management practices barrier successful cro...

We investigated changes in mineral nutrient uptake and cellular expression levels for metal transporter genes in the cadmium (Cd)/zinc (Zn) hyperaccumulator, Thlaspi caerulescens during whole plant and leaf ontogenesis under different long-term treatments with Zn and Cd. Quantitative mRNA in situ hybridization (QISH) revealed that transporter gene expression changes not only dependent on metal ...

Phytoextraction involves use of plants to remove toxic metals from soil. We examined the effects of phytoextraction practices with three plant species (Silene vulgaris, Thlaspi caerulescens, and Zea mays) and a factorial variation of soil amendments (either an ammonium or nitrate source of nitrogen and the presence or absence of an elemental sulfur supplement) on arbuscular mycorrhizal (AM) fun...

The use of chemical pesticides to protect agricultural products is a global concern because their adverse effects on the environment and public health. To avoid dangers synthetic herbicides, research has turned natural alternatives. This study was conducted evaluate allelopathic effect essential oil (EO) extracted from Origanum syriacum, onites, majorana. In addition, composition elucidated by ...
