Effects of lanthanum on growth and accumulation in roots of rice seedlings

Plant, Soil and Environment, 2013
Hormetic effects on the growth were found in the roots of rice (Oryza sativa L. cv. Shengdao 16) exposed to increasing concentrations of La3+ (0.05, 0.1, 0.5, 1.0, and 1.5 mmol/L). The results indicated that La3+ promoted the growth of rice roots at 0.05

Microbial iron cycling illuminates the biological contribution and potential climate drivers of deep-sea rare earth element enrichment

Communications Earth & Environment
Deep-sea sediments enriched in rare earth elements represent important potential resources and paleoceanographic archives. The transfer of these elements from marine particles (e.g., Fe-Mn (oxyhydr)oxides or organic matter) to phosphate phases is ...
