Summary Iron (Fe) homeostasis is crucial for all living organisms. In mammals, an integrated posttranscriptional mechanism couples the regulation of both Fe deficiency and excess responses. Whether in plants control involving common players regulates responses to still be determined. this study, molecular, genetic biochemical approaches were used investigate transcriptional excess. A activator shortage Arabidopsis, called bHLH105/ILR3, was found also negatively regulate expression ferritin...
Abstract UV-B constitutes a critical part of the sunlight reaching earth surface. The homodimeric plant photoreceptor UV RESISTANCE LOCUS 8 (UVR8) monomerizes in response to and induces photomorphogenic responses, including acclimation tolerance. REPRESSOR OF PHOTOMORPHOGENESIS 1 (RUP1) RUP2 are negative feedback regulators that operate by facilitating UVR8 ground state reversion through re-dimerization. Here we show RUP1 transcriptionally induced cryptochrome photoreceptors blue light,...
Abstract Plants must balance light capture for photosynthesis with protection from potentially harmful ultraviolet (UV) radiation. Photoprotection is mediated by concerted action of photoreceptors, but the underlying molecular mechanisms are not fully understood. In this study, we provide evidence that UV RESISTANCE LOCUS 8 (UVR8) UV-B, phytochrome red, and cryptochrome blue-light photoreceptors converge on induction FERULIC ACID 5-HYDROXYLASE 1 (FAH1) encodes a key enzyme in phenylpropanoid...
Among the mineral nutrients that are required for plant metabolism, iron (Fe) and sulphur (S) play a central role as both elements needed activity of several proteins involved in essential cellular processes. A combination physiological, biochemical molecular approaches was employed to investigate how S availability influences response Fe deficiency, using model Arabidopsis thaliana. We first observed chlorosis symptom induced by deficiency less pronounced when scarce. thus found inhibited...
Summary When exposed to shade from neighbours, competitive plants modify their growth patterns improve access light. In dense plant stands, ranging forests humid grasslands and crops, is interrupted by sunflecks penetrating the canopy. Relatively infrequent, minute-scale interruptions can significantly contribute daily light input. However, given short duration time gap between these low frequency (LFS), whether sense them was unknown. Here we show that phytochrome B (phyB), cryptochrome 1...
Abstract As sessile, photoautotrophic organisms, plants are subjected to fluctuating sunlight that includes potentially detrimental ultraviolet-B (UV-B) radiation. Experiments under controlled conditions have shown the UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8) controls acclimation and tolerance in Arabidopsis thaliana; however, its long-term impact on plant fitness naturally environments remain poorly understood. Here, we quantified survival reproduction of different mutant genotypes...
