The Phosphorylation of Ribosomal Protein in Lemna minor [PDF]
Plant Physiology, 1973 Sterile cultures of Lemna minor have been labeled with (32)P(1), and the ribosomal proteins have been examined for radioactivity. In relatively short term labeling a radioactive protein was found which ran as a single component in both urea/acetic acid and sodium lauryl sulfate gel electrophoresis.

Re‐evaluation of salt of aspartame‐acesulfame (E 962) as food additive
EFSA Journal, Volume 24, Issue 9, September 2026.Abstract The present opinion deals with the re‐evaluation of salt of aspartame‐acesulfame (E 962) as a food additive. The Panel considered that upon ingestion, E 962 dissociates into aspartame and acesulfame ions which correspond to those of the authorised sweeteners aspartame (E 951) and acesulfame K (E 950). The Panel therefore assessed the safety of

The Turnover of Nucleic Acids in Lemna minor [PDF]
Plant Physiology, 1970 A method is described for measuring the rate constants of both synthesis and degradation of nucleic acids in sterile growing cultures of Lemna minor which avoids the difficulties of environmental changes in isotope uptake and precursor pool size. In fast growing cultures the half-life of ribosomal RNA has been estimated to be between 5 and 8 days.This ...

Simulated Range Expansion Suggests Rapid Change in Biotic Resistance to a Range‐Shifting Competitor
Ecology and Evolution, Volume 16, Issue 8, August 2026.We constructed populations of Lemna minor genotypes sourced from localities near and beyond the range edge of a potential range‐shifting competitor, Spirodela polyrhiza. Following 14 weeks of exposure to low densities of S. polyrhiza, we observed subtle but significant rapid evolution and phenotypic plasticity of functional traits in L.

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes
Advanced Science, Volume 13, Issue 41, 22 July 2026.In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...

On the Life-History of Lemna minor
Botanical Gazette, 1899 1. The sporophyte of Lemna minor cannot be definitely homologized with either a stem or a leaf, but is a shoot undifferentiated except at the basal and nodal regions. 2. The secondary root is formed from a group of hypodermal cells at the node. The epidermis, which is pushed out, persists for a considerable time as the temporary root-sheath.

Selective Feeding of the Duckweed Weevil on Three Common Species of Duckweed in Japan
Plant Species Biology, Volume 41, Issue 4, July 2026.We examined the feeding preferences of the duckweed weevil on three duckweed species: Spirodela polyrhiza (Sp), Landoltia punctata (Lp), and Lemna aequinoctialis (La). Feeding assays showed that the area of Lp consumed was significantly smaller than that of Sp and La.
