Abiotic and biotic factors cause plant wounding trigger complex short- long-term responses at the local systemic levels. These are under control of signaling pathways, which still poorly understood. Here, we show that rapid activation clade-A mitogen-activated protein kinases (MAPKs) MPK3 MPK6 by depends on upstream MAPK MKK4 MKK5 but is independent jasmonic acid (JA) signaling. In addition, this fast module does not wound-triggered JA accumulation in Arabidopsis (Arabidopsis thaliana),...
Significance Although plant growth–promoting bacteria (PGPB) enhance the performance of plants, only a few mechanisms have been identified so far. We show that sulfur metabolisms in both PGPB Enterobacter sp. SA187 and Arabidopsis plants play key role salt stress tolerance. Salt induces starvation response is attenuated by SA187. metabolic mutants are hypersensitive to but can be rescued Most metabolism occurs chloroplasts linked stress-induced accumulation reactive oxygen species suppressed...
Posttranscriptional regulation of mRNA mediated by methylation at the N6 position adenine (N6-methyladenosine [m6A]) has profound effects on transcriptome in plants. Focused studies across eukaryotes offer glimpses into processes governed m6A throughout developmental and disease states. However, we lack an understanding dynamics regulatory potential during biotic stress Here, provide a comprehensive look both short-term long-term responses to pathogen signaling Arabidopsis (Arabidopsis...
Linker H1 histones play an important role in animal and human pathogenesis, but their function plant immunity is poorly understood. Here, we analyzed mutants of the three canonical variants Arabidopsis histones, namely H1.1, H1.2 H1.3. We observed that double h1.1h1.2 triple h1.1h1.2h1.3 (3h1) were resistant to Pseudomonas syringae Botrytis cinerea infections. Transcriptome analysis 3h1 mutant plants showed H1s a key regulating expression early late defense genes upon pathogen challenge....
Abstract Senescence is an important physiological process which directly affects many agronomic traits in plants. induces chlorophyll degradation, phytohormone changes, cellular structure damage, and altered gene regulation. Although these outputs are well defined, the molecular mechanisms employed not known. Using dark-induced leaf senescence (DILS) as experimental system, we investigated role of N6-methyladenosine (m6A) mRNA methylation during Arabidopsis (Arabidopsis thaliana). Plants...
Auxin (indole-3-acetic acid, IAA) is an important phytohormone involved in root growth and development. Root-interacting beneficial pathogenic fungi utilize auxin its target genes to manipulate the performance of their hosts for own needs. In order follow visualize effects fungi-colonized Arabidopsis roots, we used dual reporter construct DR5::EGFP-DR5v2::tdTomato fluorescence microscopy as well LC-MS-based analyses. We demonstrate that endophytic Piriformospora indica Mortierella hyalina...
Summary TCP transcription factors are key regulators of angiosperm cell proliferation processes. It is unknown whether their regulatory growth capacities conserved across land plants, which we examined in liverworts, one the earliest diverging plant lineages. We generated knockout mutants for Mp 1 , single ‐P clade gene Marchantia polymorpha and characterized its function by conducting morphological analyses as well messenger RNA expression, transcriptome, chemical, DNA binding studies. tcp1...
Significance Mitogen-activated protein kinases (MAPKs) function in all eukaryotes signaling extracellular stimuli to intracellular responses and ultimately link them chromatin events by targeting transcription factors remodeling complexes. In plants, MAPKs play crucial roles immunity, development, stress responses, but so far no attempts have been made identify phosphorylation of chromatin-associated proteins. By using a phosphoproteomic approach on MAPK mutants, we identified number...
Chemicals commodities and consumable, accounting for billions of ton carbon per year, are produced in an industry based on non-renewable fossil feedstocks.Oil reserves enough feeding chemical another century, therefore, it is essential finding alternative sources a progressive replacement the industrial feedstock.In this context lignocellulosic, renewable source composed mainly by polymers sugars, appears as most promising candidate.Herein, will be discussed status, challenges prospective...
Pathogen-associated molecular pattern (PAMP) recognition occurs by plasma membrane located receptors that induce among other processes nuclear gene expression. However, signaling to the compartment is restricted envelope and pore complexes. We show here four Arabidopsis lamin homologs LITTLE NUCLEI/CROWDED NUCLEI (LINC/CRWN), LINC1 plays an important role in PTI jasmonic acid (JA) signaling. linc1 knock out mutants affect PAMP-triggered MAPK activation growth inhibition, but not reactive...
In studies of plant stress signaling, a major challenge is the lack non-invasive methods to detect physiological responses and characterize plant-plant communication over time space.We acquired series phytocompound hyperspectral imaging data from maize plants following treatments: (1) individual non-infested plants, (2) experimentally subjected herbivory by green belly stink bug (no visible symptoms insect herbivory), (3) one control in separate pot but inside same cage, (4) together pot....
Recently, in temperate and neotropical regions of South America the generalist stink bug Dichelops furcatus (Hemiptera: Pentatomidae) became a new pest corn (Zea mays) seedlings. Implementation no-tillage cultivation system left organic matter covering soil, which shelters adults bugs during winter. In spring, is sowed under soybean stubble D. start to feed on To determine corn-derived volatile compounds (VOCs) that attract this species, we evaluated preferences from two hybrids with...
Abstract The proteins AtSEOR1 and AtSEOR2 occur as conjugates in the form of filaments sieve elements Arabidopsis thaliana . A reduced phytoplasma titre found infected defective-mutant Atseor1ko plants previous work raised speculation that non-conjugated SEOR2 is involved phytohormone-mediated suppression Chrysanthemum Yellows (CY)-phytoplasma infection transmitted by Euscelidius variegatus (Ev). This early long-lasting impact was revealed lack detectable phytoplasmas at an stage...
