When the abundance of the FOX1 gene product is reduced, Chlamydomonas cells grow
poorly in iron-deficient medium, but not in iron-replete medium, suggesting that FOX1 …

A toxidez de Mn pode ser um problema comum nas regiões tropicais com predominância de

A number of transition metals, such as Cu, Zn, Mn, Fe, Ni, and Co, are trace elements
necessary in small amounts for the proper growth and development of organisms, including …

Manganese (Mn) is an essential mineral nutrient. Mn transport proteins have a critical role in
mediating acquisition of Mn by the roots, partitioning Mn into organelles such as the vacuole …

Higher plants take up essential nutrients from the rhizosphere, in which several nutrients
tend to be insoluble, thus limiting their availability. Deficiencies of the micronutrients Fe and …
