An extract of a rotenone-containing plant yam bean, Pachyrhizus erosus (L.) Urban, seeds was tested against the diamondback moth, Plutella xylostella (L.) in a greenhouse to determine its potential as an oviposition deterrent and compared with coumarin and rutin, known as diamondback moth oviposition deterrent compounds, rotenone, and an extract of Peruvian cube root, at a concentration of 0.5%...

Community assembly following disturbance is a key process in determining the composition and function of future community. However, replicated studies community at whole-ecosystem scales are rare. Here, we describe series whole-lake experiments, which recovery zooplankton communities was tracked an ecosystem-scale disturbance, that is, application piscicide, rotenone. Using before-after-control...

Rotenone and rotenoid-containing botanicals, important insecticides and fish poisons, are reported to have anticancer activity in rats and mice. The toxic action of rotenone is attributed to inhibition of NADH:ubiquinone oxidoreductase activity and the purported cancer chemopreventive effect of deguelin analogs has been associated with inhibition of phorbol ester-induced ornithine decarboxylase...

The Parkinsonian syndrome induced by pesticides is associated with the impairment of mitochondrial function. Toxicants that inhibit selectively NADH-dehydrogenase activity, as rotenone or pyridaben, also show a selective inhibition of O2 uptake and respiratory control in rat brain mitochondria in the presence of NAD-dependent substrates. The IC50 of rotenone and pyridaben for complex I inhibiti...

MALATE OXIDATION IN PLANT MITOCHONDRIA PROCEEDS THROUGH THE ACTIVITIES OF TWO ENZYMES: a malate dehydrogenase and a NAD(+)-dependent malic enzyme. In cauliflower, mitochondria malate oxidation via malate dehydrogenase is rotenone- and cyanide-sensitive. Addition of exogenous NAD(+) stimulates the oxidation of malate via malic enzyme and generates an electron flux that is both rotenone- and cyan...

The effects of disturbance on local species diversity have been well documented, but less recognized is the possibility that disturbances can alter diversity at regional spatial scales. Since regional diversity can dictate which species are available for recolonization of degraded sites, the loss of diversity at regional scales may impede the recovery of biodiversity following a disturbance. To...

Rotenone is a widely used pesticide and a potent inhibitor of mitochondrial complex I (NADH-quinone reductase) that elicits the degeneration of dopaminergic neurons and thereby the appearance of a parkinsonian syndrome. Here we have addressed the alterations induced by rotenone at the functional, morphological and molecular levels in the retina, including those involving both dopaminergic and n...

The expression of complex I and two homologues of bacterial and yeast NADH dehydrogenases, NDA and NDB, have been studied in potato leaf mitochondria. The mRNA level of NDA is completely light dependent and shows a diurnal rhythm with a sharp maximum just after dawn. NDA protein quantity and internal rotenone-insensitive NADH dehydrogenase activity are also light dependent. These findings sugge...

The data presented in this article are related to the research article entitled "Rotenone decreases ischemia-induced injury by inhibiting mitochondrial permeability transition in mature brains" (Rekuviene et al., 2017) [1]. Data in this article present the direct effects of rotenone on calcium retention capacity (CRC) in isolated normal cortex and cerebellum mitochondria, effects of rotenone in...
