Oxylipin glucosides (2-4) were isolated from Lemna paucicostata with their structures and absolute configurations elucidated by spectroscopic and chemical methods. Compounds 2-4 were glucosides of C14 oxylipin which were synthesized from alpha-linolenic acid via the 9-lipoxygenase pathway.

Microsatellite primers are a valuable tool to use for both observational and experimental studies in numerous taxa. Here, we develop 18 16 microsatellite markers the widespread duckweeds Lemna minor Spirodela polyrhiza, respectively. Only four were not polymorphic when tested on samples from Europe Western Pennsylvania, USA.

The aim of the present study was to explore the aerial parts of the Polygonatum verticillatum for various biological activities such as phytotoxic, insecticidal and leishmanicidal properties. Outstanding phytotoxicity was observed for the crude extract and its subsequent solvent fractions against Lemna acquinoctialis Welv at tested doses of 5, 50 and 500 μg/ml. Complete growth inhibition (100%)...

Growth studies with Lemna minor revealed the additive and synergistic growth-inhibiting properties of the canaline-urea cycle amino acids. Simultaneous canavanine and canaline treatment caused an additive reduction in frond production. Ureidohomoserine interacted with canaline or canavanine to affect synergistically L. minor growth by enhancing individual canavanine or canaline toxicity and inc...
