Crown roots are the main components of fibrous root system in rice (Oryza sativa). WOX11, a WUSCHEL-related homeobox gene specifically expressed emerging crown meristem, is key regulator development. However, nature WOX11 function development has remained elusive. Here, we identified AP2/ERF protein, ERF3, which interacts with and was initials during growth. Functional analysis revealed that ERF3 essential for acts auxin- cytokinin-responsive expression. Downregulation wox11 mutants produced...
Shoot-borne crown roots are the major root system in cereals. Previous work has shown that Wuschel-related homeobox gene WOX11 is necessary and sufficient to promote rice (Oryza sativa) emergence elongation. Here, we show recruits ADA2-GCN5 histone acetyltransferase module activate downstream target genes meristem. Rice ADA2 GCN5 highly expressed meristem be essential for cell division growth. commonly regulate a set of root-specific involved energy metabolism, wall biosynthesis, hormone...
Plant DNA methylation that occurs at CG, CHG, and CHH sites (H = A, C, or T) is a hallmark of the repression repetitive sequences transposable elements (TEs). The rice (Oryza sativa) genome contains about 40% sequence TEs displays specific patterns genome-wide methylation. mechanism responsible for unclear. Here, we analyzed function OsDDM1 (Deficient in Methylation 1) OsDRM2 methylation, TE repression, small RNA accumulation, gene expression. We show essential high levels CHG and, to lesser...
Summary Elevated ambient temperatures affect plant growth and substantially impact biomass crop yield. Recent results have indicated that chromatin remodelling is critical in thermal responses but how histone modification dynamics affects response has not been clearly demonstarted. Here we show Arabidopsis deacetylase genes HDA 9 , 15 19 play distinct roles to elevated temperature. hda9 hda19 mutants showed a warm‐temperature‐insensitive phenotype at 27°C, whereas hda15 plants displayed...
Abstract Sperm chromatin is typically transformed by protamines into a compact and transcriptionally inactive state 1,2 . cells of flowering plants lack protamines, yet they have small, active nuclei with condensed through an unknown mechanism 3,4 Here we show that histone variant, H2B.8, mediates sperm nuclear condensation in Arabidopsis thaliana Loss H2B.8 causes enlarged dispersed chromatin, whereas ectopic expression somatic produces smaller aggregated chromatin. This result demonstrates...
Noncoding transcription induces chromatin changes that can mediate environmental responsiveness, but the causes and consequences of these mechanisms are still unclear. Here, we investigate how antisense (termed COOLAIR ) interfaces with Polycomb Repressive Complex 2 (PRC2) silencing during winter-induced epigenetic regulation Arabidopsis FLOWERING LOCUS C ( FLC ). We use genetic analyses on lines ineffective or hyperactive for pathway in combination computational modeling to define...
Rice inflorescence meristem (IM) activity is essential for panicle development and grain production. How chromatin epigenetic mechanisms regulate IM remains unclear. Genome-wide analysis revealed that in addition to genes involved the vegetative reproductive transition, many metabolic protein synthetic were activated compared with shoot apical a change H3K27me3/H3K4me3 ratio was an important factor differential expression of genes. Thousands gained or lost H3K27me3 IM, downregulation H3K27...
Recent advances in rice flowering studies have shown that the accurate control of by photoperiod is regulated key mechanisms involve regulation genes including Heading date1 (Hd1), Early hd1 (Ehd1), Hd3a, and RFT1. The chromatin mechanism involved presently not well known. Here we show enhancer zeste [E(z)] SDG711 SDG718, which encode polycomb repressive complex2 (PRC2) subunit required for trimethylation histone H3 lysine 27 (H3K27me3), are respectively, long day (LD) short (SD) genes....
The rice root system is mainly composed of post-embryonic shoot-borne roots called crown roots. WOX11, encoding a WUSCHEL-related homeobox domain transcription factor, key regulator growth and development in (Oryza sativa. L). In addition to specifically activating development, WOX11 also involved lateral initiation, hair formation, abiotic stresses. However, the gene regulatory network downstream remains largely unknown. Here, we studied transcriptome wox11 tips by RNA-Seq determined direct...
Abstract Plant-specific WOX family transcription factors play important roles ranging from embryogenesis to lateral organ development. The WOX1 factors, which belong the modern clade of family, are known regulate outgrowth leaf blade specifically in mediolateral axis; however, role compound development remains unknown. Phylogenetic analysis whole tomato (Solanum lycopersicum) indicates that there 10 members represent modern, intermediate, and ancient clades. Using phylogenetic a reverse...
H3K27me3 is a repressive chromatin mark of genes and catalyzed by homologs Enhancer zeste [E(z)], component Polycomb-repressive complex 2 (PRC2), while DNA methylation that occurs in CG non-CG (CHG CHH, where H A, C, or T) contexts hallmark transposon silencing plants. However, the relationship between gene repression remains unclear. In addition, mechanism PRC2 recruitment to specific not known Here, we show SDG711, rice (Oryza sativa) E(z) homolog, required maintain many developmental...
Gentiopicroside is promising as an important secoiridoid compound against pain. The present study aimed to investigate the analgesic effect and probable mechanism of on Diabetic Peripheral Neuropathy (DPN), figure out association among Gentiopicroside, dyslipidemia PPAR- γ/AMPK/ACC signaling pathway.DPN rat models were established by streptozotocin RSC96 cells cultured. Hot, cold mechanical tactile allodynia conducted. Blood lipids, nerve blood flow, Motor Nerve Conduction Velocity (MNCV)...
The size of leaf and seed organs, determined by the interplay cell proliferation expansion, is closely related to final yield quality forage crops. Yet cellular molecular mechanisms underlying organ modulation remain poorly understood, especially in legumes. Here, MINI ORGAN1 (MIO1), which encodes an F-box protein SMALL LEAF AND BUSHY1 (SLB1) recently reported control lateral branching Medicago truncatula, was identified as a key regulator size. We show that loss-of-function MIO1/SLB1...
Abstract Epigenetic reprogramming occurs during reproduction to reset the genome for early development. In flowering plants, mechanistic details of parental methylation remodeling in zygote remain elusive. Here we analyze allele-specific DNA rice hybrid zygotes and embryo development show that paternal is predominantly remodeled match maternal allelic levels upon fertilization, which persists after first zygotic division. The pattern supports maternal-biased gene expression activation (ZGA)...
Optimizing plant architecture is an efficient approach for breeders to increase crop yields, and phytohormones such as gibberellins (GAs) play important role in controlling growth. Medicago truncatula a model legume species, but the molecular mechanisms underlying its are largely unknown. In this study, we examined tobacco retrotransposon Tnt1-tagged mutant collection of M. identified dwarf increased branching 1 (dib1), which exhibited extreme dwarfism numbers lateral branches. By analysis...
In species with compound leaves, the positions of leaflet primordium initiation are associated local peaks auxin accumulation. However, role during late developmental stages and outgrowth leaves remains largely unknown. Using genome resequencing approaches, we identified insertion sites at four alleles LATERAL LEAFLET SUPPRESSION1 (LLS1) gene, encoding biosynthetic enzyme YUCCA1 in Medicago truncatula. Linkage analysis complementation tests showed that lls1 mutant phenotypes were caused by...
Proteins in the Chromodomain-Helicase/ATPase-DNA-binding domain (CHD) family are divided into three groups. The function of group I CHD proteins nucleosome positioning is well established, while that II members (represented by CHD3/Mi2) remains unclear. Using high-throughput approaches, we investigated rice (Oryza sativa) protein CHR729 positioning, gene expression, histone methylation, and binding. Our data revealed chr729 mutation led to increased occupancy genome altered expression...
Plant height is a vital agronomic trait that greatly determines crop yields because of the close relationship between plant and lodging resistance. Legumes play unique role in worldwide agriculture; however, little attention has been given to molecular basis their height. Here, we characterized first dwarf mutant
