Abstract The INDUCER OF CBF EXPRESSION (ICE)–C-REPEAT BINDING FACTOR/DRE FACTOR1 (CBF/DREB1) transcriptional pathway plays a critical role in modulating cold stress responses Arabidopsis thaliana. Dissecting crucial upstream regulatory signals or components of the ICE-CBF/DREB1 cascade will enhance our understanding plant cold-tolerance mechanisms. Here, we show that jasmonate positively regulates to freezing Arabidopsis. Exogenous application significantly enhanced tolerance with without...
The Arabidopsis NPR1 gene is a positive regulator of inducible plant disease resistance. Expression induced by pathogen infection or treatment with defense-inducing compounds such as salicylic acid (SA). Transgenic plants overexpressing exhibit enhanced resistance to broad spectrum microbial pathogens, whereas underexpressing the are more susceptible infection. These results suggest that regulation expression important for activation defense responses. In present study, we report...
Leaf senescence is regulated by diverse developmental and environmental factors. Exogenous jasmonic acid (JA) can induce leaf senescence, whereas auxin suppresses this physiological process. Crosstalk between JA signaling has been well studied, but not during JA-induced senescence. Here, we found that upon methyl jasmonate treatment, Arabidopsis thaliana wrky57 mutants produced typical symptoms, such as yellowing leaves, low chlorophyll content, high cell death rates. Further investigation...
MicroRNAs (miRNAs) are comprised of approximately 21 nucleotide (nt) RNAs that play important regulatory roles in growth and development by targeting mRNAs for cleavage or translational repression. In Arabidopsis, more than one hundred miRNAs have been identified but the biological functions only a limited number them determined molecular genetic analysis. miR396 is miRNA conserved among dicot monocot plants. has two loci (MIR396a MIR396b) targets six Growth-Regulating Factor (GRF) genes...
SNF 1-RELATED PROTEIN KINASE 2 (SnRK2) is a family of plant-specific protein kinases which the key regulator hyper-osmotic stress signalling and abscisic acid (ABA)-dependent development in various plants. Among rice subclass-I -II SnRK2s, osmotic stress/ABA–activated kinase (SAPK2) may be primary mediator ABA signaling. However, SAPK2 has not been comprehensively characterized. In this study, we elucidated functional properties using loss-of-function mutants produced with CRISPR/Cas9...
The WRKY transcription factors have been demonstrated to play crucial roles in regulating stress responses; however, the exact mechanisms underlying their involvement responses are not fully understood. Arabidopsis WRKY8 was predominantly expressed roots and highly upregulated by salt treatment. Disruption of rendered plants hypersensitive salt, showing delayed germination, inhibited post-germination development accelerated chlorosis. Further investigation revealed that interacted with VQ9,...
Sulfur is a macronutrient that necessary for plant growth and development. Sulfate, major source of sulfur, taken up by roots transported into various tissues assimilation. During sulfate limitation, expression miR395 significantly up-regulated. targets two families genes, ATP sulfurylases (encoded APS genes) transporter 2;1 (SULTR2;1, also called AST68), both which are involved in the metabolism pathway. Their transcripts suppressed strongly miR395-over-expressing transgenic Arabidopsis,...
Abstract Seed germination and postgerminative growth are regulated by a delicate hormonal balance. Abscisic acid (ABA) represses Arabidopsis thaliana seed growth, while brassinosteroids (BRs) antagonize ABA-mediated inhibition promote these processes. However, the molecular mechanism underlying BR-repressed ABA signaling remains largely unknown. Here, we show that Glycogen Synthase Kinase 3-like kinase BRASSINOSTEROID INSENSITIVE2 (BIN2), critical repressor of BR signaling, positively...
microRNAs (miRNAs) are a class of negative regulators that take part in many processes such as growth and development, stress responses, metabolism plants. Recently, miRNAs were shown to function plant nutrient metabolism. Moreover, several identified the response nitrogen (N) deficiency. To investigate functions other N deficiency, deep sequencing technology was used detect expression small RNAs under N-sufficient -deficient conditions. The results showed members from same miRNA families...
The regulation of iron (Fe) homeostasis is critical for plant survival. Although the systems responsible reduction, uptake, and translocation Fe have been described, molecular mechanism by which plants sense status coordinate expression deficiency-responsive genes largely unknown. Here, we report that two basic helix-loop-helix-type transcription factors, bHLH34 bHLH104, positively regulate in Arabidopsis (Arabidopsis thaliana). Loss function bHLH104 causes disruption deficiency response...
Significance Previous studies have shown that abscisic acid (ABA) has a positive effect on virus infection, and ethylene negative effect. However, the possible crosstalk between ABA signaling during plants–virus interaction remains unclear. Our current results demonstrate WRKY8 is involved in defense response against crucifer-infecting tobacco mosaic (TMV-cg) through direct regulation of expression ABI4 , ACS6 ERF104 thus may mediate TMV-cg–Arabidopsis interaction.
Abstract Background Since whole genome sequences of rice were made publically accessible, the number articles onnew genes has increased remarkably. The Committee on Gene Symbolization, Nomenclature and Linkage(CGSNL) Rice Genetics Cooperative published gene nomenclature system for encouragedresearchers to follow rules before publishing their results. CGSNL provides an on-line registration systemfor newly identified prevent conflicts and/or duplication name in journal articles. Findings...
Abstract The CRISPR/Cas9-sgRNA system has been developed to mediate genome editing and become a powerful tool for biological research. Employing the manipulation accelerated research expanded researchers’ ability generate genetic models. However, method evaluating efficiency of sgRNAs is lacking in plants. Based on nucleotide compositions secondary structures which have experimentally validated plants, we instituted criteria design efficient sgRNAs. To facilitate assembly multiple sgRNA...
Iron (Fe) deficiency is a limiting factor for the normal growth and development of plants, many species have evolved sophisticated systems adaptation to Fe-deficient environments. It still unclear how plants sense Fe status coordinate expression genes responsive deficiency. In this study, we show that bHLH transcription bHLH115 positive regulator Fe-deficiency response. Loss-of-function causes strong symptoms alleviates deficiency, whereas its overexpression opposite effect. Chromatin...
RNA-dependent RNA polymerases (RdRPs) have been implicated in posttranscriptional gene silencing (PTGS) and antiviral defense. An Arabidopsis RdRP (SDE1/SGS2) has previously shown to be required for transgene-induced PTGS but no general role On the other hand, we recently that transgenic tobacco deficient an inducible (NtRdRP1) activity became more susceptible both Tobacco mosaic virus Potato X. Thus, different RdRPs may distinct roles closely related In present study, analyzed of a newly...
