Ultraviolet-B (UV-B) radiation can have wide-ranging impacts on plants. UV-B exposure can decrease the rate of photosynthesis, alter pigment concentrations, and damage DNA, proteins, and lipids; however, not all species are equally sensitive. Lemna minor and Spirodela polyrhiza, two sympatric aquatic plants, were exposed to 5 or 11 days of artificial UV-B radiation for 6 hours per day, and moni...

The steady state concentrations of S-containing compounds formed in Lemna paucicostata Hegelm. 6746 in response to variations in source and concentrations of sulfur were measured. Neither growth rates nor protein accumulation were markedly affected by the various growth conditions. Ignoring complications due to possible compartmentation, the results are consistent with internal pools of both SO...

Duckweeds are of special interest, as they are naturally growing weeds that have the capacity to tolerate and remove toxic pollutants, including heavy metals from the environment. Studies have revealed that duckweed (Lemna minor) can tolerate and remove heavy metals from aqueous solutions. In the present study, the efficiency of L. minor in the removal of Ni and Cr individually from aqueous sol...
