Seeds are a crucial stage in plant life. They contain the nutrients necessary to initiate the development of a new organism. Seeds also represent an important source of nutrient for human beings. Iron (Fe) and zinc (Zn) deficiencies affect over a billion people worldwide. It is therefore important to understand how these essential metals are stored in seeds. In this work, Particle-Induced X-ray...

Many central metabolic processes require iron (Fe) as a cofactor and take place in specific subcellular compartments such as the mitochondrion or the chloroplast. Proper Fe allocation in the different organelles is thus critical to maintain cell function and integrity. To study the dynamics of Fe distribution in plant cells, we have sought to identify the different intracellular iron pools by c...

this study is aimed to identify sources of particulate matter with mean aerodynamic diameterbelow 10 μm (pm10) present in the atmosphere of the metropolitan area of mexico city (mamc), usingsamples obtained from january 1st to june 30th, 2009, analyzed with x-ray spectrometric techniques.minivol samplers were used to collect samples on polycarbonate filters in three sites (north, center, andsou...

Copper oxide nanoparticles (CuO-NPs) have been increasingly released in aquatic ecosystems over the past decades as they are used many applications. Cu toxicity to different organisms has already highlighted literature, however mechanisms of nanoparticulate form remain unclear. Here, we investigated effect, transfer and localization CuO-NPs compared salt on plant Myriophyllum spicatum, an ecoto...
