Uptake and transformation of phenols by duckweed (Lemna gibba)
Phenol and its derivatives are common constituents of numerous natural and synthetic chemicals including pesticides. As a consequence of anthropological activities, a portion of them may reach various water bodies as contaminants which will have a great impact on the aquatic environment including biota. Aquatic plants are known to be one of the major habitants and food for many species and henc...
متن کاملTwo 10-bp regions are critical for phytochrome regulation of a Lemna gibba Lhcb gene promoter.
Two small regions of the promoter of an Lhcb gene encoding a light-harvesting chlorophyll a/b protein were identified as essential in conferring phytochrome responsiveness by using a transient expression assay. Initially, 5' deletion analysis of cabAB19, an Lhcb2 gene of Lemna, showed that sequences within the region from -174 to -104 relative to the start of transcription were necessary for ph...

15 صفحه اولGrowth response of Lemna gibba L. (duckweed) to copper and nickel phytoaccumulation Effet de l’accumulation de Cu et Ni sur la croissance de Lemna gibba L. (lentilles d’eau)
To assess the tolerance and phytoaccumulation ability of the duckweed Lemna gibba L. to copper (Cu) and nickel (Ni), the aquatic plants were exposed to different concentrations of Cu and Ni (0.1 – 2.0 mg/L) in quarter Coïc and Lesaint solution at pH = 6.0 (± 0.1) and under a daily regime of 12 h light. Copper and nickel were tolerated by L. gibba at concentrations ≤ 0.3 mg/L and ≤ 0.5 mg/L, res...
