Further Oxygenated Fatty Acids from Lemna minor
Journal of Natural Products, 1987In a re-investigation of the aquatic plant Lemna minor, two novel cyclopen-tanoid Cl6 fatty acids, 6a and 7a, have been isolated and characterized as the corresponding methyl esters on the basis of their physical and chemical features. A biogenetic pathway similar to that of the prostaglandins is suggested for these compounds. © 1987, American Chemical

Lemna minor L. Artbeschreibung: Sehr klein, auf der Wasseroberfläche schwimmend, aus einem flachen, ovalen bis kreisrunden, 2-6 mm langen, 3-5nervigen blattartigen Spross und einer einzigen daran hängenden, bis 10 cm langen Wurzel bestehend. Die Sprosse vermehren sich vegetativ und hängen zu 2-6 aneinander. Selten blühend.

A linear diterpene diol from Lemna minor
Phytochemistry, 1984Abstract Four known isoprenoids were isolated from Lemna minor besides a novel diterpene which was attributed the structure (4 R )-4-hydroxyisophytol by spectroscopic studies and chemical correlation.

Genetic transformation of duckweed Lemna gibba and Lemna minor
In Vitro Cellular & Developmental Biology - Plant, 2001We developed efficient genetic transformation protocols for two species of duckweed, Lemna gibba (G3) and Lemna minor (8627 and 8744), using Agrobacterium-mediated gene transfer. Partially differentiated nodules were co-cultivated with Agrobacterium tumefaciens harboring a binary vector containing β-glucuronidase and nptII expression cassettes ...

Summary By control of growth conditions a continuous culture of Lemna minor was obtained. Total protein in Lemna minor corresponds to 16 % of dry matter. The fraction elutable with 0.015 M orthophosphate buffer, p H 7, is prevailing in the protein isolated from L. minor . The amino acid composition of L.

Glycosidation of chlorophenols by Lemna minor
Environmental Toxicology and Chemistry, 2004Abstract Metabolic fate of xenobiotics in plant tissues has an important role in the ultimate fate of these compounds in natural and engineered systems. Chlorophenols are an important class of xenobiotics used in a variety of biocides and have been shown to be resistant to microbial degradation.

Alumina nanoparticles enhance growth of Lemna minor
Aquatic Toxicology, 2011The industrial use of nanoparticles is rapidly increasing, and this has given rise to concerns about potential biological impacts of engineered particles released into the environment. So far, relatively little is known about uptake, accumulation and responses to engineered nanoparticles by plants. In this study, the effects of alumina nanoparticles on

Lemna Minor Growth Inhibition Test
2005This chapter describes Environment Canada’s method entitled Biological Test Method: Test for Measuring the Inhibition of Growth Using the Freshwater Macrophyte, Lemna minor (EC, 1999). Research has lead to minor changes in the methodology that are described where appropriate. Applications of the method are also described herein. The L.
