Genetic transformation of duckweed Lemna gibba and Lemna minor

In Vitro Cellular & Developmental Biology - Plant, 2001
We 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 ...

A linear diterpene diol from Lemna minor

Phytochemistry, 1984
Abstract 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.

Protein in Lemna minor L.

Biochemie und Physiologie der Pflanzen, 1975
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.

The uptake of boron by Lemna minor

Aquatic Botany, 1978
This study characterizes Lemna minor L. as a bio-accumulator of boron relative to other species of aquatic macrophytes. Laboratory experiments using 0.01, 0.11 and 1.01 mg B l−1 indicated that ambient boron was a determining factor in rate of boron accumulation in plant tissue. Field studies showed that the tissue boron concentration of L.

Phytotoxicity of silver nanoparticles to Lemna minor L

Environmental Pollution, 2011
The use of silver nanoparticles (AgNPs) in commercial products has increased significantly in recent years. Although there has been some attempt to determine the toxic effects of AgNPs, there is little information on aquatic plants which have a vital role in ecosystems. This study reports the use of Lemna minor L.

The rhizosphere of an aquatic plant (Lemna minor)

Canadian Journal of Microbiology, 1969
Dominant epiphytes colonizing the surface of Lemna minor were identified and enumerated. The distribution of these organisms compared to populations on inert surfaces at depths 0, [Formula: see text], 1, 2, 4 and 8 in. revealed greater than a 100-fold increase in population density. This enhanced carrying capacity of the plant diminished with depth.

Alumina nanoparticles enhance growth of Lemna minor

Aquatic Toxicology, 2011
The 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

Interpretation of Adaptive Plasticity in Lemna minor

Oikos, 1992
The adaptive significance of plasticity was evaluated for eight genotypes of Lemna minor L. based on two inter-related assumptions: a display of plasticity in the form of increased growth rate after environmental amelioration is directly more adaptive than an absence of plasticity; and a display of plasticity in the form of decreased growth rate after ...

TRANSLOCATION EXPERIMENTS IN THE FIELD WITH THE LEMNA GIBBA - LEMNA MINOR COMPLEX

Acta Botanica Neerlandica, 1974
SUMMARY Translocation of a clone of the flat form of the Lemna gibba – Lemna minor complex to the site of a gibbous population resulted in a persistence of the flat form, which is indicative of a genetical basis of the frond shape of this flat clone.
