Distribution and Biosynthesis of 20-Hydroxyecdysone in Plants of Achyranthes japonica Nakai
The incorporation of [2-14C]-mevalonic acid into 20E did not differ significantly depending on plant organs and developmental stages, suggesting that biosynthesis of 20E is not restricted to particular organs or growth stages.
Change of Low-Molecular-Weight Metabolome of Alien Species Potamogeton pectinatus L. in Lake Ladoga in Comparison with Population of Native Range
The plasticity of the metabolism of P. pectinatus allows it to adapt to a wide spectrum of abiotic conditions and different biological environments and to settle in new habitats, primarily those under anthropogenic impact.
Effects of Phytoecdysteroids (PEDS) Extracted from Cyanotis arachnoidea on Rumen Fermentation, Enzyme Activity and Microbial Efficiency in a Continuous-Culture System
The results showed that increasing supplementation levels of PEDS resulted in incremental digestibility of dry matter (DMD) and organic matter (OMD), but unchanged digestionibility of neutral detergent fiber (NDFD), crude protein (CPD) and acid detergent acid (ADFD), suggesting an alteration of rumen fermentation pattern occurring due to PEDs supplementation in the diet.
Low-molecular-weight metabolites of aquatic macrophytes growing on the territory of Russia and their role in hydroecosystems
This article deals with the issues of studying low-molecular-weight volatile organic compounds (VOCs) of aquatic macrophytes growing in Russia under different environmental conditions and geographic


The analysis of phytoecdysteroids in single (preflowering stage) specimens of fat hen, Chenopodium album
A simple microextraction procedure together with an ecdysteroid-specific radioimmunoassay (RIA) have been used to quantify the levels of phytoecdysteroid in small (<50 mg dry wt.) samples of plant
Variability of invertebrate herbivory on the submerged macrophyte Potamogeton perfoliatus
Invertebrate herbivory was studied in twenty-eight populations of the submerged macrophyte Potamogeton perfoliatus in Danish streams and lakes in mid-June and it was concluded that shredders acting as facultative herbivores were the most important invertebrate herbsivores on P.perfoliatus.
Ecdysteroids fromPycnogonum litorale (Arthropoda, Pantopoda) act as chemical defense againstCarcinus maenas (Crustacea, Decapoda).
The present results demonstrate for the first time chemical defense in arthropods in a marine predator-prey relationship and provide evidence that ES contained in one animal can act as feeding deterrents on another animal.
Sago pondweed (Potamogeton pectinatus L.): A literature review
Sago pondweed (Potamogeton pectinatus L.) is a submersed macrophyte of nearly cosmopolitan distribution of worldwide importance as a waterfowl food but also can be a nuisance in irrigation canals and recreational areas.
Lake Veluwe, a Macrophyte-dominated System under Eutrophication Stress
This work presents a Growth Analysis Model for Potamogeton pectinatus L. as a Function of Plant Age and Irradiance Level during Growth, and concludes that general Conclusions and Implications for Lake Management are positive.
Intraspecific variation in Potamogeton pectinatus L.: a controlled laboratory experiment.
In a controlled laboratory experiment, the question was addressed whether intraspecific variation in Potamogeton pectinatus L. has a genotypic component. Two populations from contrasting habitats in

Ecdysteroid receptors: a comparison of cytoplasmic and nuclear receptors from crayfish hypodermis.
Cytoplasmic and nuclear ecdysteroid receptors from intermolt Orconectes limosus integument have been compared. The specificities as well as the KD values for three [3H]ecdysteroids are very similar
