Successful floral meristem (FM) determinacy is critical for subsequent reproductive development and the plant life cycle. Although phytohormones cytokinin auxin interact to coregulate many aspects of development, whether how function in FM remain unclear. Here, we show that Arabidopsis thaliana, homeostasis determinacy. In this developmental context, promotes expression AUXIN RESPONSE FACTOR3 (ARF3) repress activity. ARF3 directly represses ISOPENTENYLTRANSFERASE (IPT) family genes...
Significance Histone deacetylases (HDACs) belong to a large protein family in plants, and little is known about how target specificity of each HDAC achieved. We show that paired SANT (SWI3/DAD2/N-CoR/TFIII-B) domain-containing protein, POWERDRESS, specifically acts with HDA9 confer the deacetylation histone H3 lysine residues at set genomic targets regulate various biological processes. Our study elucidates functional correlation between proteins HDACs plants.
Termination of the stem cells in floral meristem (also known as determinacy) is critical for reproductive success plants, and molecular activities regulating determinacy are precisely orchestrated during course development. In Arabidopsis thaliana, regulators include several transcription factor genes, such APETALA2 (AP2), AGAMOUS (AG), SUPERMAN (SUP), CRABSCLAW (CRC), well a microRNA (miRNA), miR172, which targets AP2. How miRNA genes coordinately regulated to achieve unknown. A mutation...
It has been reported that Arabidopsis chloroplast accD transcripts undergo RNA editing and loss of accD-C794 does not affect plant growth under normal conditions. To date, the exact biological role remained elusive. Here, we reveal an unexpected for in response to heat stress. Loss results a yellow dwarf phenotype with decreased gene expression stress, artificial improvement C794-edited enhances tolerance Arabidopsis. These data suggest confers planta. We also found treatment product acetyl...
Plants frequently encounter relatively low and fluctuating potassium (K+) concentrations in soil, with roots serving as primary responders to this stress. Histone modifications, such de-/acetylation, can function epigenetic markers of stress-inducible genes. However, the signaling network between histone modifications low-K+ (LK) response pathways remains unclear. This study investigated regulatory role Deacetylase Complex 1 (HDC1) root growth Arabidopsis thaliana under K+ deficiency Using a...
Abscisic acid (ABA) regulates many aspects of plant development, including seed dormancy and germination, root growth stomatal closure. Plant SKP1 proteins are subunits the SCF complex E3 ligases, which regulate several phytohormone signalling pathways through protein degradation. However, little is known about participating in ABA signalling. Here, we report that overexpression Triticum aestivum SKP1-like 1 (TSK1) Arabidopsis thaliana (Arabidopsis) resulted delayed germination...
It has been perplexing that DNA topoisomerases, enzymes release supercoils, play specific roles in development. In this study, using a floral stem cell model Arabidopsis thaliana, we uncovered role for TOPOISOMERASE1α (TOP1α) Polycomb Group (PcG) protein-mediated histone 3 lysine 27 trimethylation (H3K27me3) at, and transcriptional repression of, the maintenance gene WUSCHEL (WUS). We demonstrated H3K27me3 deposition at other PcG targets also requires TOP1α. Intriguingly, of some, as well...
Fusarium wilt disease poses a severe threat to watermelon cultivation by affecting the yield and quality of fruit. We had previously found that rhizosphere microbiome has significant impact on ability plants resist development salicylic acid (SA) is closely related this phenomenon. Therefore, in study, role SA as mediator between microbes activating resistance against oxysporum f. sp. niveum (FON) infection was explored through physiological, biochemical, metagenomic sequencing experiments....
Fusarium wilt disease is one of the major diseases causing a decline in watermelon yield and quality. Researches have informed that phytohormones play essential roles regulating plants growth, development, stress defendants. However, molecular mechanism salicylic acid (SA), jasmonic (JA), abscisic (ABA) resistance to remains unknown. In this experiment, we established SA, JA, ABA determination system roots, analyzed their against compared resistant susceptible varieties using transcriptome...
Premature senescence of leaves causes a reduced yield and quality rice by affecting plant growth development. The regulatory mechanisms underlying early leaf are still unclear. Leaf 1 (LS1) gene encodes C2H2-type zinc finger protein that is localized to both the nucleus cytoplasm. In this study, we constructed mutant named (ls1) with premature phenotype using CRISPR/Cas9-mediated editing LS1 gene. ls1 mutants exhibited chlorophyll content. expression levels were higher in mature or senescent...
The bacteria pathogen Xanthomonas oryzae pv. (Xoo) infects rice and causes the severe disease of blight. As central regulator salic acid (SA) signaling pathway, NPR1 is responsible for sensing SA inducing expression pathogen-related (PR) genes in plants. Overexpression OsNPR1 significantly increases resistance to Xoo. Although some downstream were found be regulated by OsNPR1, how affects interaction rice-Xoo alters Xoo gene remains unknown. In this study, we challenged wild-type OsNPR1-OE...
Gelsemium elegans contains multiple alkaloids with pharmacological effects, thus researchers focus on the identification and application of extracted from G. elegans. Regretfully, spatiotemporal distribution in is still unclear. In this study, desorption electrospray ionization mass spectrometry imaging (DESI-MSI) was applied to simultaneously analyze pharmacologically important different organ/tissue sections at growth stages. Finally, 23 were visualized roots, stems leaves seedling stage...
Phytohormones play a key role in regulating tiller number. Ascorbic acid (Asc)-phytohormone interaction plays pivotal the regulation of senescence. We analysed relationship between Asc and enzyme concentrations gene transcript abundances related to signal perception strigolactones (SLs), contents four phytohormones (abscisic acid, ABA; jasmonic JA; indole acetic IAA; cytokinin, CTK), synthesis or transportation these phytohormones. Our results showed that deficiency leads upregulation...
Abstract An amperometric immunosensor for phytohormone abscisic acid was developed based on in situ chemical reductive growth of gold nanoparticles glassy carbon electrode. First, an approximate 10 nm layer sputtered uniformly onto the electrode surface, and then were grown directly antibody adsorption by immersing into H2AuCl4 solution. Determination enzyme-linked competitive immunoreaction between free enzyme-labeled to bind immobilized The linear response from ng/ml µg/ml with a detection...
Chalkiness is one of the key factors determining rice quality and price. Ascorbic acid (Asc) a major plant antioxidant that performs many functions in plants. l-Galactono-1,4-lactone dehydrogenase (l-GalLDH, EC1.3.2.3) an enzyme catalyzes final step Asc biosynthesis Here we show l-GalLDH-overexpressing transgenic rice, GO-2, which has constitutively higher leaf content than wild-type (WT) plants, exhibits significantly reduced grain chalkiness. Higher foliar ascorbate/dehydroascorbate...
Copy number variation (CNV) may have phenotypic effects by altering the expression level of gene(s) or regulatory element(s) contained. It is believed that CNVs play pivotal roles in controlling plant architecture and other traits plant. However, CNV contributing to special remain largely unknown. Here we report a involved rice modulating tiller leaf angle. In genome Oryza sativa ssp. japonica cv. Nipponbare, found locus Loc_Os08g34249 derived from 13,002-bp tandem duplication nearby region...
