Abstract Temperature compensation is a defining feature of circadian oscillators, yet no components contributing to the phenomenon have been identified in plants. We tested 27 accessions Arabidopsis thaliana for leaf movement at range constant temperatures. The showed varying patterns temperature compensation, but clear associations geographic origin could be made. Quantitative trait loci (QTL) were mapped period and amplitude Columbia by Landsberg erecta (CoL) Cape Verde Islands (CvL)...
Abstract Circadian clocks are required to coordinate metabolism and physiology with daily changes in the environment. Such have several distinctive features, including a free-running rhythm of approximately 24 h ability entrain both light or temperature cycles (zeitgebers). We previously characterized EARLY FLOWERING4 (ELF4) locus Arabidopsis (Arabidopsis thaliana) as being important for robust rhythms. Here, it is shown that ELF4 necessary at least two core clock functions: entrainment an...
Abstract The photoreceptor phytochrome B (phyB) interconverts between the biologically active Pfr (λmax = 730 nm) and inactive Pr 660 forms in a red/far-red–dependent fashion regulates, as molecular switch, many aspects of light-dependent development Arabidopsis thaliana. phyB signaling is launched by conformer mediated specific protein–protein interactions its downstream regulatory partners, whereas conversion to terminates signaling. Here, we provide evidence that phosphorylated planta at...
Abstract Arabidopsis thaliana EARLY FLOWERING3 (ELF3) is essential for the generation of circadian rhythms. ELF3 has been proposed to restrict light signals oscillator through phytochrome photoreceptors, but that not explicitly shown. Furthermore, genetic action within clock had remained elusive. Here, we report a functional characterization analysis elf3-12 allele, which encodes an amino acid replacement in conserved domain. Circadian oscillations persisted, and unlike elf3 null alleles,...
Abstract The circadian system of Arabidopsis (Arabidopsis thaliana) includes feedback loops gene regulation that generate 24-h oscillations. Components these remain to be identified; none the known components is completely understood, including ZEITLUPE (ZTL), a implicated in regulated protein degradation. ztl mutations affect both and developmental responses red light, possibly through ZTL interaction with PHYTOCHROME B (PHYB). We conducted large-scale genetic screen identified additional...
Abstract Plants substantially alter their developmental programme upon changes in the ambient temperature. The 21–24 nt small RNAs (sRNAs) are important gene expression regulators, which play a major role development and adaptation. However, little is known about how different sRNA classes respond to We profiled populations four tissues of Arabidopsis thaliana plants grown at 15°C, 21°C, 27°C. found that only fraction (0.6%) loci temperature‐controlled. identified thermoresponsive microRNAs...
RNA interference (RNAi) is mediated by small, 20-24-nt-long, non-coding regulatory (s)RNAs such as micro (mi) and small interfering (si) RNAs via the action of ARGONAUTE (AGO) proteins. High-throughput sequencing size-separated sRNA pools plant crude extracts revealed that majority canonical miRNAs were associated with high molecular weight RNA-induced silencing complexes co-migrating AGO1 (HMW RISC). In contrast, 24-nt-long siRNAs found in association low AGO4 (LMW Intriguingly, we...
SUMMARY DNA methylation, a dynamic epigenetic mark influencing gene expression, is regulated by demethylases that remove methylated cytosines at genomic regions marked the INCREASED METHYLATION (IDM) complex. In Arabidopsis , IDM3, small α‐crystalline domain‐containing protein, stabilises IDM To investigate its role in tomato, we generated slidm3 mutants using genome editing. These displayed ‘hairy’ phenotype with increased glandular trichomes, resembling hairplus ( hap ) mutant. Affinity...
Barley (Hordeum vulgare L.) is an economically important crop cultivated in temperate climates all over the world. Adverse environmental factors negatively affect its survival and productivity. RNA silencing a conserved pathway involved regulation of growth, development stress responses. The key components are Dicer-like proteins (DCLs), Argonautes (AGOs) RNA-dependent polymerases (RDRs). Despite economic importance, there no available comprehensive report on barley machinery regulation. In...
Abstract The circadian clock of the model plant Arabidopsis (Arabidopsis thaliana) is made up a complex series interacting feedback loops whereby proteins regulate their own expression across day and night. early bird (ebi) mutation that causes to speed up: ebi plants have short periods, phase gene expression, are flowering. We show EBI associates with ZEITLUPE (ZTL), known act in as posttranslational mediator protein degradation. However, not degraded by its interaction ZTL. Instead, ZTL...
Plant genomes contain two major classes of innate immune receptors to recognize different pathogens. The pattern recognition perceive conserved pathogen-associated molecular patterns and the resistance genes with nucleotide-binding (NB) leucine-rich repeat (LRR) domains specific pathogen effectors. precise regulation is important since unregulated expression NB-LRR can inhibit growth may result in autoimmunity absence infection. It was shown that a subset miRNAs could target act as an...
Summary In some plant–virus interactions plants show a sign of healing from virus infection, phenomenon called symptom recovery. It is assumed that the meristem exclusion essential to this process. The discovery RNA silencing provided possible mechanism explain and Here we evidence not reason for in Nicotiana benthamiana infected with Cymbidium ringspot (CymRSV). Transcriptome analysis followed by situ hybridization shed light on changes gene expression shoot apical (SAM) infection. We...

Here, we report the draft genome sequence of M. together description properties its annotation. The consists 608 contigs total size 4,449,424 bp an average coverage 150×. exhibits G + C content 68.7 %, contains 4754 protein coding 52 RNA genes,...
Circadian clocks are biochemical timers regulating many physiological and molecular processes according to the day/night cycles. The function of oscillator relies on negative transcriptional/translational feedback loops operated by so-called clock genes encoded proteins. Previously, we identified small GTPase LIGHT INSENSITIVE PERIOD 1 (LIP1) as a circadian-clock-associated protein that regulates light input in model plant Arabidopsis thaliana. We showed LIP1 is also required for suppressing...
Abstract Circadian clocks are biochemical timers regulating many physiological and molecular processes according to the day/night cycle. The small GTPase LIGHT INSENSITIVE PERIOD1 (LIP1) is a circadian clock-associated protein that regulates light input clock. In absence of LIP1, effect on free-running period length much reduced. Here, we show in addition suppressing red blue light-mediated photomorphogenesis, LIP1 also required for light-controlled inhibition endoreplication tolerance salt...
Small regulatory RNAs, such as microRNAs (miRNAs) and small interfering RNAs (siRNAs) have emerged important transcriptional post-transcriptional regulators controlling a wide variety of physiological processes including fruit development. Data are, however, limited for their potential roles in developmental determining economically traits crops. The current study aimed to discover characterize differentially expressed miRNAs siRNAs sweet pepper (Capsicum annuum) during expansion....
