X-ray Imaging of Zinc Uptake and Accumulation in Hyperaccumulator Thlaspi caerulescens
The use of high energy x-ray fluorescence as a trace metal probe offers scientists an innovative tool for research. One application is the study of heavy metal accumulation in plant systems. The test species Thlaspi caerulescens has the ability to accumulate massive amounts of zinc, cadmium, and lead from contaminated soils as a form of bioremediation. In order to understand the efficiency of t...
متن کاملAntimony uptake, efflux and speciation in arsenic hyperaccumulator Pteris vittata.
Even though antimony (Sb) and arsenic (As) are chemical analogs, differences exist on how they are taken up and translocated in plants. We investigated 1) Sb uptake, efflux and speciation in arsenic hyperaccumulator Pteris vittata after 1 d exposure to 1.6 or 8 mg/L antimonite (SbIII) or antimonate (SbV), 2) Sb uptake by PV accessions from Florida, China, and Brazil after 7 d exposure to 8 mg/L...
متن کاملAcute Toxicity and Accumulation of Iron, Manganese and, Aluminum in Caspian Kutum Fish (Rutilus kutum)
Background: Iron, manganese, and aluminum are three abundant metals on earth and their concentrations have increased in aquatic environments as a result of natural and industrial activities. This study was undertaken to report the median acute toxicity (LC50) and accumulation of the sub-lethal concentration (10% 96-h LC50) of iron (Fe), manganese (Mn) and aluminum (Al) in kutum (Rutilus kutum) ...
متن کاملNutrient Uptake by Woody Root Systems
The fine-root system of perennial, dicot woody species can be dominated by brown roots. Although as much as 90% of the surface area of a root system can be in this category of roots, the nutrient uptake characteristics of brown roots are not well understood. If this part of the root system has active uptake, then its significance is obvious. If it does not then modelling predictions of nutrient...
متن کامل: examining l2 teachers’ corrective feedback types in relation to learners’ uptake, proficiency levels, and context types
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
