Abstract In rice (Oryza sativa), the shoot-borne crown roots are major root type and initiated at lower stem nodes as part of normal plant development. However, regulatory mechanism development is poorly understood. this work, we show that a WUSCHEL-related Homeobox (WOX) gene, WOX11, involved in activation emergence growth. WOX11 was found to be expressed emerging later cell division regions meristem. The expression could induced by exogenous auxin or cytokinin. Loss-of-function mutation...
Asian cultivated rice consists of two subspecies: Oryza sativa subsp. indica and O. japonica Despite the fact that accounts for over 70% total production worldwide is genetically much more diverse, a high-quality reference genome has yet to be published. We conducted map-based sequencing lines, Zhenshan 97 (ZS97) Minghui 63 (MH63), which represent major varietal groups subspecies are parents an elite Chinese hybrid. The sequences were assembled into 237 181 (MH63) contigs, with accuracy...
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...
Abstract The SILENT INFORMATION REGULATOR2 (SIR2) family proteins are NAD+-dependent histone deacetylases. Sir2 is involved in chromatin silencing at the mating-type loci, rDNA, and telomeres yeast associated with lifespan extension yeast, worms, flies, but also a broader range of additional functions. In this work, we investigated role OsSRT1, one two SIR2-related genes found rice (Oryza sativa). We show that OsSRT1 widely expressed nuclear protein higher levels rapidly dividing tissues....
YABBY and WUSCHEL-LIKE HOMEOBOX (WOX) genes have been shown to play important roles in lateral organ formation meristem function. Here, we report the characterization of functional relationship between rice (Oryza sativa) YAB3 WOX3 leaf development. Rice is closely related maize (Zea mays) ZmYAB14 Arabidopsis (Arabidopsis thaliana) FILAMENTOUS FLOWER (FIL), whereas highly conserved with narrow sheath1 (NS1) NS2 PRESSED (PRS). In situ hybridization experiments revealed that expression both...
Gibberellin (GA) biosynthesis is regulated by feedback control providing a mechanism for GA homeostasis in plants. However, regulatory elements involved the are not known. In this report, we show that rice (Oryza sativa) YABBY1 (YAB1) gene had similar expression pattern as key biosynthetic genes GA3ox2 and GA20ox2. Overexpression of YAB1 transgenic resulted semidwarf phenotype could be fully rescued applied GA. Quantification endogenous content revealed increases GA(20) decreases GA(1)...
Histone methylation is an important epigenetic modification in chromatin function, genome activity, and gene regulation. Dimethylated or trimethylated histone H3 lysine 27 (H3K27me2/3) marks silent repressed genes involved developmental processes stress responses plants. However, the role mechanism of dynamic removal H3K27me2/3 during activation remain unclear. Here, we show that rice (Oryza sativa) Jumonji C (jmjC) protein JMJ705 encodes a demethylase specifically reverses H3K27me2/3. The...
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...
Histone demethylation is known to regulate transcription, but its role in other processes largely unknown. We report a for the histone demethylase LSD1/KDM1A DNA damage response (DDR). show that LSD1 recruited directly sites of damage. H3K4 dimethylation, major substrate LSD1, reduced at an LSD1-dependent manner. The E3 ubiquitin ligase RNF168 physically interacts with and we find this interaction be important recruitment sites. Although loss did not affect initial formation pH2A.X foci,...
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...
Histone lysine acylations by short-chain fatty acids are distinct from the widely studied histone acetylation in chromatin, although both modifications regulated primary metabolism mammalian cells. It remains unknown whether and how acylation interact to regulate gene expression plants that have regulatory pathways of metabolism.We identify 4 butyrylation (Kbu) sites (H3K14, H4K12, H2BK42, H2BK134) 45 crotonylation (Kcr) on rice histones mass spectrometry. Comparative analysis genome-wide...
Sirtuins, a family of proteins with homology to the yeast silent information regulator 2 (Sir2), are NAD+-dependent histone deacetylases and play crucial roles in energy sensing regulation animal cells. Plants autotrophic organisms display distinct features carbon metabolism. It remains largely unexplored whether how plant cells sense energy/redox status control metabolic flux under various growth conditions. In this work, we show that rice nuclear sirtuin OsSRT1 not only functions as an...
Roots are essential organs for anchoring plants, exploring and exploiting soil resources, establishing plant-microorganisms communities in vascular plants. Rice has a complex root system architecture consisting of several types, including primary roots, lateral crown roots. Crown roots constitute the major part rice play important roles during growing period. Recently, we have refined mechanism that involves ERF3/WOX11 interaction is required to regulate expression genes cytokinin signaling...
Abstract Crown roots are the main components of root systems in cereals. Elucidating mechanisms crown formation is instrumental for improving nutrient absorption, stress tolerance, and yield cereal crops. Several members WUSCHEL-related homeobox (WOX) lateral organ boundaries domain (LBD) transcription factor families play essential roles controlling development rice (Oryza sativa). However, functional relationships among these factors regulating genes involved remain unclear. Here, we...
Abstract Background Epigenetic marks are reprogrammed during sexual reproduction. In flowering plants, DNA methylation is only partially remodeled in the gametes and zygote. However, timing functional significance of remodeling plant gametogenesis remain obscure. Results Here we show that starts after male meiosis rice, with non-CG methylation, particularly at CHG sites, being first enhanced microspore subsequently decreased sperm. Functional analysis rice methyltransferase genes CMT3a CMT3b...
