“…A similar observation has been made for C. aspera, which inhibited strongly S. obliquus when Chara and S. obliquus were kept together, but the negative impact was lost when Chara had been removed prior to the experiment (Van Donk & Van de Bund, 2002). Van Donk & Van de Bund (2002) explained this by immediate degradation/disappearance of allelopathic substances, because the allelopathic substances from Chara are volatile (Anthoni et al, 1980) and therefore may be lost rapidly (Blindow & Hootsmans, 1991;Van Donk & Van de Bund, 2002). In the current study, a rapid removal of volatile sulphuric compounds might have occurred during the filtration step, which was included in the experimental design between phase I and II.…”

“…Allelopathically active compounds are often directed at photosynthesis (Gross, 2003) and have been extracted from Elodea canadensis (WiumAndersen, 1987), Chara globularis (Anthoni et al, 1980;Wium-Andersen et al, 1982), and Myriophyllum spicatum (Gross & Su¨tfeld, 1994). In those studies 14 C-radiotracer techniques were applied to demonstrate the allelopathy, while in the current study photosynthetic performance of Scenedesmus was distilled from F PSII measurements.…”

“…Several species of submerged macrophytes may contain allelochemicals that suppress algal growth. Sulphuric compounds isolated from the green macroalga Chara globularis may inhibit phytoplankton photosynthesis (Anthoni et al, 1980). Planas et al (1981) found growth inhibition by phenolic compounds isolated from Myriophyllum spicatum, some of which are also released into the surrounding water (Gross et al, 1996;Nakai et al, 1996Nakai et al, , 1999Gross, 2003).…”

Importance of Nutrient Competition and Allelopathic Effects in Suppression of the Green Alga Scenedesmus obliquus by the Macrophytes Chara, Elodea and Myriophyllum

Possible allelopathic effects of substances released from the macrophytes Chara globularis, Elodea canadensis, Myriophyllum spicatum on the common green alga Scenedesmus obliquus were tested in the laboratory with plastic plants and untreated medium as controls. A two-phase approach was used in which first the effects of physical presence of plants was studied (phase I) followed by the effects of plant culture filtrates (phase II). In the presence of plastic plants growth was reduced only marginally, but strong growth inhibition of Scenedesmus occurred in the physical presence of all macrophytes. In contrast, filtrates from Chara had no growth inhibitory effect on Scenedesmus. Myriophyllum filtrate reduced particle-based growth rate by 7% compared to filtration controls, while Elodea culture filtrate reduced volume-based growth by 12%, chlorophyll-based growth by 28% and particle-based growth by 15%. Photosystem IIefficiency of Scenedesmus was reduced in all three macrophyte treatments in phase I, but not in filtrates from macrophyte cultures (phase II). Thus, while enzyme activity or other physiological aspects may have been affected, the current study yielded no proof for allelopathically active compounds being directed at photosynthesis. Mean particle volume (MPV) of Scenedesmus was not influenced by macrophyte exudates and cultures remained dominated by unicells. The strong growth inhibitory effects found for Scenedesmus in the physical presence of macrophytes, but not in plastic controls, and no or weaker response in nutrientenriched filtrates, suggest nutrient competition was a more powerful driving factor than allelochemicals. However, the experimental design does not exclude disappearance of allelochemicals during the filtration process.

“…Possible mechanisms behind the toxicity and repellence to both invertebrates and vertebrates are numerous, such as membrane damaging activity or interference with catecholamine metabolism and other neural control mechanisms (reviewed by Singleton and Kratzer 1969). A chemical isolated from Chara globularis (4-methylthio-1,2-dithiolane, also named charatoxin, Anthoni et al 1980) blocks the cholinergic receptors and thus inhibits neural functions, and kills houseflies (Musca domestica) (Jacobsen and Pedersen 1983). Such compounds have, however, not been identified from M. spicatum.…”

Macrophyte architecture can structure predator-prey interactions, but it is the chemicals within the plant that may actually be lethal. We conducted aquarium experiments to study the effects of common aquatic macrophytes (Myriophyllum spicatum, Myriophyllum sibiricum, and Chara tomentosa) and a predator (perch, Perca fluviatilis) on the survival, habitat choice, swimming, and feeding activities of Baltic littoral planktivores, mysids Neomysis integer and Praunus flexuosus, and three-spined stickleback (Gasterosteus aculeatus) larvae. Chemicals excreted by M. spicatum in a dense patch caused high mortality (73% to 89%) in both mysid species but not in sticklebacks, whereas M. sibiricum and C. tomentosa had no lethal effects. In lower stem densities stickleback larvae and N. integer avoided M. spicatum even in the presence of predator signals, and M. spicatum lowered the swimming and feeding activities of stickleback larvae. Only P. flexuosus did not avoid M. spicatum vegetation. Areas occupied by M. spicatum seem to be highly unsuitable habitats for littoral mysids and three-spined stickleback larvae. Because M. spicatum is a dominant macrophyte in the study area and eutrophication further increases its abundance, it may strongly influence the occurrence and distribution of mysids and fish larvae in the littoral ecosystems of the Baltic Sea.

A rich variety of organosulfur compounds are found in living systems. A list of biochemically notable organosulfur compounds would include, among others, the essential amino acids cysteine and methionine, peptides such as glutathione, and the recently characterized biologically extremely potent glutathione deriva tive leukotriene C-1 (1)(1) (Fig. 1) (the "slow reacting substance" of anaphylaxis (SRS) which is known for its role in the lungs during asthma attacks), polycyclic peptide antibiotics such as bacitracin, gliotoxin, cephalosporin, penicillin, and the recently discovered β-lactam antibiotic thienamycin (2)(2), cofactors and vitamins such as thiamine, biotin, coenzyme A and α-lipoic acid, a bio logical alkylating agent, S-adenosylmethionine, the biological redox systems ferredoxin and rubredoxin and sulfur-containing bases found in bacterial transfer-RNA such as 4-thiouracil (3).A remarkable range of simpler organosulfur compounds are known to be widely distributed throughout the plant kingdom (3,4,5,6). These compounds often make important contributions to the odor and flavor of many of the common comestibles. In some instances these sulfur compounds may also serve by their odor and taste to repel predators or to act for the plant as resistance factors against infection by microorganisms (e.g. as natural pest icides). Not to be outdone, some insects such as the onionmaggot, Hylemya antiqua, and turnip (or vegetable) weevil, Listroderes obliquas, have evolved so that some of the same organosulfur compounds act as attractants and stimulate egg laying and biting (Z)A number of insects and higher animals have also been found to possess unusual small organosulfur molecules which may serve as defensive secretions, sex attractants, or scent markers · In many cases the low molecular weight organosulfur compounds occur in plants (and possibly in animals as well) in an odorless com bined form (e.g., as peptides or glycosides) and are released enzymatically when the tissue is injured or stimulated, i.e. during attack by a predator. Finally it should be noted that certain sulfur compounds reported to be of natural origin may 0097-6156/81/015 8-0003$05.00/0
