Phytotoxicity of Photosystem II (PSII) herbicides to coral
Recent reports of contamination of the Great Barrier Reef Marine Park by herbicides used in antifouling paints and in agriculture have caused concern over the possible effects on corals in nearshore areas. Pulse-Amplitude Modulated (PAM) chlorophyll fluorescence techniques were used to examine changes in the maximum effective quantum yield (∆F/Fm’) of symbiotic dinoflagellates within the host t...
متن کاملKinetics of Action of Different Photosystem II Herbicides on Thylakoids
The kinetics o f inhibition o f photosystem II electron transfer by different diuron-like herbi cides (ureas, triazines, triazinones. biscarbam ates, uraciles) were studied, mainly by chloro phyll fluorescence measurem ents. Uracil derivatives and cyanazine, a particu lar triazine, were the slowest acting com pounds. The half-times o f action were strongly tem perature-dependent and were o f ...
متن کاملPhytotoxicity of Four Photosystem II Herbicides to Tropical Seagrasses
Coastal waters of the Great Barrier Reef (GBR) are contaminated with agricultural pesticides, including the photosystem II (PSII) herbicides which are the most frequently detected at the highest concentrations. Designed to control weeds, these herbicides are equally potent towards non-target marine species, and the close proximity of seagrass meadows to flood plumes has raised concerns that sea...
متن کاملHypertonicity-induced projections reflect cell polarity in mouse metaphase II oocytes: involvement of microtubules, microfilaments, and chromosomes.
A previous study showed that with hypertonic sucrose treatment, a projection is formed in mouse metaphase II (MII) oocytes in proximity to the spindle and chromosomes, where a polarized cortical domain is located. However, little is known about the mechanisms involved in this process. Here, we designed a series of experiments to test the hypothesis that hypertonicity is the induction factor for...
متن کاملPressure-induced depolymerization of spindle microtubules. II. Thermodynamics of in vivo spindle assembly
The present experiments were designed to test whether the simple equilibrium assembly model proposed by Inoué could predict variations in spindle microtubule assembly in response to changes in hydrostatic pressure as it does for changes in temperature. The results were also analyzed according to a model based on nucleated condensation polymerization since this recently appears to be the mechani...
