摘要:... It was previously demonstrated that PIFs accumulated in darkness and repressed seedling photomorphogenesis, and that PIFs linked different photosensory and hormonal pathways to control plant growth and development. In this study, we show that PIFs positively regulate the ABA ...

摘要:... A pilot study was conducted to compare the quantity and community component of bacteria in surface water collected from filtration effluent before UV disinfection with different doses of UV, and those 1 and 2 days afterwards, in darkness. The aim was to elucidate the rela...

摘要:Abstract(#br)In order to understand how darkness/irradiance and low nighttime temperature might alter physiology of Ulva prolifera under lower salinity conditions, we analyzed the growth rates, water content, superoxide dismutase (SOD) activity, total soluble proteins (SPs) and...

摘要:... To determine whether light and darkness have similar effects in birds, the only non-mammalian group that displays sleep patterns comparable to mammals, we examined the effects of lighting changes on sleep and wakefulness in the pigeon. We quantified sleep behavior (i.e., bila...

摘要:Abstract(#br)This study examined the effects of darkness and shadows on the behavioral responses of piglets. Twenty-six 1-week-old piglets were used for two tests. In the test of ‘response to darkness’, piglets were held in an enclosure, then allowed access to a like-sized a...

摘要:... Here we report a T-DNA insertion mutant ( atdfb-3 ) of the plastidial folylpolyglutamate synthetase gene ( AtDFB ) was defective in folate metabolism and nitrogen metabolism under nitrate-limited conditions in darkness. Exogenous applied 5-formyl-tetrahydrofolate (5-F-THF) co...

摘要:... In the present study, we monitored circadian activity rhythms and voluntary ethanol consumption under standard 12:12 light–dark (LD) cycles, and in constant light (LL) and constant darkness (DD). Experiment 1 employed male C3H/He inbred mice, while Experiment 2 employe...

摘要:Abstract(#br)In the photic zone, phytoplankton experience diurnal variation in darkness. However, prolonged exposure to aphotic conditions influences their physiological state. Pigment composition is a useful biomarker to decipher cells physiological state and adaptive response t...

摘要:Abstract(#br)Although a variety of physiological and psychological stressors stimulate a significant increase in adrenomedullin (ADM) levels, suggesting a regulatory or protective role for ADM in countering the hypothalamo–pituitary–adrenal (HPA) axis activation following these stressors, it is still unknown whether light or darkness...

摘要:... The degree of darkness, elemental composition, carbon and nitrogen stable isotope ratios, 13 C nuclear magnetic resonance spectra, and X-ray diffraction patterns of humic acids extracted from the soils before and after heating were measured. The proportion of humic acids ...
