Pirins are cupin-fold proteins, implicated in apoptosis and cellular stress eukaryotic organisms. Pirin1 (PRN1) plays a role seed germination transcription of light- ABA-regulated gene under specific conditions the model plant system Arabidopsis thaliana. Herein, we describe that PRN1 possesses previously unreported functions can profoundly affect early growth, development, responses. In vitro-translated quercetinase activity. When was incubated with G-protein-α subunit (GPA1) inactive...
Abstract Plants must tightly regulate iron (Fe) sensing, acquisition, transport, mobilization, and storage to ensure sufficient levels of this essential micronutrient. POPEYE (PYE) is an responsive transcription factor that positively regulates the deficiency response, while also repressing genes for maintaining homeostasis. However, little known about how PYE plays such contradictory roles. Under iron-deficient conditions, pPYE:GFP accumulates in root pericycle pPYE:PYE–GFP localized...
UV-radiation elicits a suite of developmental (photomorphogenic) and protective responses in plants, but early post-germination have received little attention, particularly intensively bred plants economic importance. We examined germination, hypocotyl elongation, leaf pubescence subcellular germinating and/or etiolated soybean (Glycine max (L.) Merr.) seedlings response to treatment with discrete wavelengths UV-A or UV-B radiation. demonstrate differential germinating/young range UV that...
Time course transcriptome datasets are commonly used to predict key gene regulators associated with stress responses and explore functionality. Techniques developed extract causal relationships between genes from high throughput time expression data limited by low signal levels coupled noise sparseness in points. We deal these limitations proposing the Cluster Differential Alignment Algorithm (CDAA). This algorithm was designed process first grouping based on stages of activity then using...
The seed-to-seedling transition is impacted by changes in nutrient availability and light profiles, but still poorly understood. Phenylalanine affects early seedling development; thus, the roles of arogenate dehydratases (ADTs), which catalyze phenylalanine formation, were studied germination during exploring impact conditions specific hormone responses adt mutants Arabidopsis thaliana. ADT gene expression was assessed distinct tissues for light-quality dependence seedlings each six-member...
The iron deficiency response in plants is a complex biological process with host of influencing factors. ability to precisely modulate this at the transcriptome level would enable genetic manipulations allowing survive nutritionally poor soils and accumulate increased content edible tissues. Despite collected experimental data describing different aspects plants, no attempts have been made towards aggregating information into descriptive predictive model gene expression changes over time. We...
Peroxisomes are membrane-bound organelles in most eukaryotes carrying out fatty acid β-oxidation. catabolize acids derived from triacylglycerol stored lipid droplets. This catabolism fuels oilseed germination but generates damaging reactive oxygen species. contain antioxidant enzymes to decompose these species, chaperones refold and disaggregate misfolded aggregated proteins, proteases degrade damaged proteins. In addition, obsolete peroxisomes can be degraded through pexophagy, a...
Peroxisomes house diverse metabolic pathways that are essential for plant and animal survival, including enzymes produce or inactivate toxic byproducts. Despite the importance of peroxisomes their collaborations with other organelles, mechanisms trigger prevent peroxisome turnover cellular impacts impaired incompletely understood. When Arabidopsis thaliana LON2, a peroxisomal protein chaperone protease capacity, is disrupted, dysfunction instability in ensue. Paradoxically, preventing...
Plants respond to stress through highly tuned regulatory networks. While prior works identified master regulators of iron deficiency responses in A. thaliana from whole-root data, identifying that act at the cellular level is critical a more comprehensive understanding homeostasis. Within root epidermis complex molecular mechanisms facilitate reduction and uptake rhizosphere are known be regulated by bHLH transcriptional regulators. However, many questions remain about control these...
