Manganese accumulates in leaves of radishes grown in manganese supplemented soils (1143.10)

Manganese accumulates primarily in nuclei of cultured brain cells.

Manganese (Mn) is known to pass across the blood-brain barrier and interact with dopaminergic neurons. However, the knowledge on the subcellular distribution of Mn in these cell types upon exposure to Mn remained incomplete. This study was designed to investigate the subcellular distribution of Mn in blood-brain barrier endothelial RBE4 cells, blood-cerebrospinal fluid barrier choroidal epithel...

Manganese Toxicity in Sugarcane Plantlets Grown on Acidic Soils of Southern China

Ratoon sugarcane plantlets in southern China have suffered a serious chlorosis problem in recent years. To reveal the causes of chlorosis, plant nutrition in chlorotic sugarcane plantlets and the role of manganese (Mn) in this condition were investigated. The study results showed that the pH of soils growing chlorotic plantlets ranged from 3.74 to 4.84. The symptoms of chlorosis were similar to...

Population Structure of Manganese-Oxidizing Bacteria in Stratified Soils and Properties of Manganese Oxide Aggregates under Manganese–Complex Medium Enrichment

Manganese-oxidizing bacteria in the aquatic environment have been comprehensively investigated. However, little information is available about the distribution and biogeochemical significance of these bacteria in terrestrial soil environments. In this study, stratified soils were initially examined to investigate the community structure and diversity of manganese-oxidizing bacteria. Total 344 c...

Some Manganese-iron Relationships in Tomato Fruits Grown on Marl, Peat and Sand Soils

take as well as to the supply and uptake of calcium. Evans and Troxler (4) working with blossom-end rot, a physiological disorder of the tomato fruit, have indicated that or ganic acids may have an influence on calcium assimilation. Blossom-end rot seems to be similar to blackheart of celery in that calcium appears to be a limiting factor as associated with conditions similar to those associate...
