PDZ motifs are modular protein–protein interaction domains, consisting of 80–120 amino acid residues, whose function appears to be the direction intracellular proteins multiprotein complexes. In skeletal muscle, there a few known PDZ-domain proteins, which include neuronal nitric oxide synthase and syntrophin, both components dystrophin complex, actinin-associated LIM protein, binds spectrin-like repeats α-actinin-2. Here, we report identification characterization new muscle protein...
In this report, we show that nitric oxide affects mitochondrial functionality in plant cells and reduces total cell respiration due to strong inhibition of the cytochrome pathway. The residual depends on alternative pathway novel synthesis oxidase occurs. These modifications are associated with depolarisation membrane potential release c from mitochondria, suggesting a conserved signalling plants animals. This signal cascade is triggered at level induces about 20% death. order achieve higher...
pH Gradient in Light of Electroneutrality Photosynthesis plant chloroplasts depends on a proton gradient to convert light energy into adenosine triphosphate. Studying Arabidopsis , Carraretto et al. (p. 114 published online 5 September; see the Perspective by Rochaix ) identified potassium channel TPK3 stacked membranes chloroplast's thylakoids as key sustaining gradient. As thylakoid lumen acidifies exposure light, electroneutrality derives from activity. was able optimize chloroplast...
Plant species have evolved myriads of solutions, including complex cell type development and regulation, to adapt dynamic environments. To understand this cellular diversity, we profiled tomato root translatomes. Using xylem differentiation in tomato, examples functional innovation, repurposing, conservation transcription factors are described, relative the model plant Arabidopsis. Repurposing innovation genes further observed within an exodermis regulatory network illustrate its function....
Understanding how roots modulate development under varied irrigation or rainfall is crucial for of climate-resilient crops. We established a toolbox tagged rice lines to profile translating mRNAs and chromatin accessibility within specific cell populations. used these study in range environments: plates the lab, controlled greenhouse stress recovery conditions, outdoors paddy. Integration mRNA data resolves regulatory networks following: cycle genes proliferating cells that attenuate DNA...
Salinity tolerance has been extensively investigated in recent years due to its agricultural importance. Several features, such as the regulation of ionic transporters and metabolic adjustments, have identified salt hallmarks. Nevertheless, complexity trait, results achieved date met with limited success improving rice plants when tested field, thus suggesting that a better understanding mechanisms is still required. In this work, differences between two varieties contrasting sensitivities...
Since the discovery of 20 genes encoding for putative ionotropic glutamate receptors in Arabidopsis (Arabidopsis thaliana) genome, there has been considerable interest uncovering their physiological functions. For many these receptors, neither channel formation and/or roles nor localization within plant cells is known. Here, we provide, to our knowledge, new information about vivo protein and give insight into biological so-far uncharacterized GLUTAMATE RECEPTOR3.5 (AtGLR3.5), a member...
Over the recent years, several proteins that make up mitochondrial calcium uniporter complex (MCUC) mediating Ca2+uptake into matrix have been identified in mammals, including channel-forming protein MCU. Although six MCU gene homologs are conserved model plant Arabidopsis (Arabidopsis thaliana) which mitochondria can accumulate Ca2+, a functional characterization of has lacking. Using electrophysiology, we show one isoform, AtMCU1, gives rise to Ca2+-permeable channel activity be observed...
Abstract Plants utilize environmental information to modify their developmental trajectories for optimal survival and reproduction. Over a century ago, day length (photoperiod) was identified as major factor influencing transitions, particularly the shift from vegetative reproductive growth. In rice (Oryza sativa), exposure lengths shorter than critical threshold accelerates flowering, while longer days inhibit this process. This response is mediated by HEADING DATE 1 (Hd1), zinc finger...
Here, for the first time, a comprehensive transcriptomics study is presented of leaf senescence in legume model Medicago truncatula, providing broad overview differentially expressed transcripts involved this process. The cDNA-amplification fragment length polymorphism (AFLP) technique was used to identify > 500 genes, which were cloned and sorted into functional categories according their gene ontology annotation. Comparison between datasets Arabidopsis M. truncatula reveals common...
Among cereal crops, salinity tolerance is rare and complex. Multiple genes control numerous pathways, which constitute plant's response to salinity. Cell cultures act as model system are useful investigate the can possibly mimic a stress. In present study two indica rice varieties, KS-282 Super Basmati exhibited contrasting sodium chloride (NaCl) stress were used establish cell cultures. The showed salt at 100 mM NaCl. High level of intracellular hydrogen peroxide (H2O2) nitric oxide (NO)...
Background Large-scale sequencing projects have now become routine lab practice and this has led to the development of a new generation tools involving function prediction methods, bringing latter back fore. The advent Gene Ontology, with its structured vocabulary paradigm, provided computational biologists an appropriate means for task. Methodology We present here novel method called ARGOT (Annotation Retrieval Ontology Terms) that is able process quickly thousands sequences functional...
Bioinformatic approaches have allowed the identification of twenty genes, grouped into three subfamilies, encoding for homologues animal ionotropic glutamate receptors (iGLRs) in Arabidopsis thaliana model plant. Indirect evidence suggests that plant iGLRs function as non-selective cation channels. In present work we provide biochemical and electrophysiological evidences chloroplast localization receptor(s) family 3 (iGLR3) spinach. A specific antibody, recognizing putative locates iGLR3 to...
Abstract Despite the important achievement of high-resolution structures several prokaryotic channels, current understanding their physiological roles in bacteria themselves is still far from complete. We have identified a putative two transmembrane domain-containing channel, SynCaK, genome freshwater cyanobacterium Synechocystis sp. PCC 6803, model photosynthetic organism. SynCaK displays significant sequence homology to MthK, calcium-dependent potassium channel isolated Methanobacterium...
Clear evidence has highlighted a role for hormones in the plant stress response, including salt stress. Interplay and cross-talk among different hormonal pathways are of vital importance abiotic tolerance. A genome-wide transcriptional analysis was performed on leaves roots three-day treated untreated plants two Italian rice varieties, Baldo Vialone Nano, which differ sensitivity. Genes correlated with were identified analyzed. The contents abscisic acid, indoleacetic cytokinins,...
