Rapid progress has been made regarding the understanding of brassinosteroid (BR) signaling in Arabidopsis. However, little is known about BR monotyledons. Here, we characterized a rice dwarf and low-tillering (dlt) mutant cloned corresponding gene via map-based cloning. DLT encodes new member plant-specific GRAS family. The phenotype dlt similar to BR-deficient or mutants rice. In addition, both lamina bending coleoptile elongation assays show that insensitive much less responsive...
Rhabdomyosarcoma (RMS) is a childhood cancer originating from skeletal muscle, and patient survival poor in the presence of metastatic disease. Few determinants that regulate metastasis development have been identified. The receptor tyrosine kinase FGFR4 highly expressed RMS tissue, suggesting role tumorigenesis, although its functional importance has not defined. Here, we report identification mutations human tumors lead to activation present evidence it functions as an oncogene RMS. Higher...
Landslide detection from extensive remote-sensing imagery is an important preliminary work for landslide mapping, inventories, and hazard assessment. Aimed at development of automatic procedure detection, a new method presented in this study. We achieved objective using scene classification based on the bag-of-visual-words (BoVW) representation combination with unsupervised probabilistic latent semantic analysis (pLSA) model k-nearest neighbour (k-NN) classifier. Given image, we divided it...
The Jiangmen Underground Neutrino Observatory (JUNO) is proposed to determine the neutrino mass hierarchy using an underground liquid scintillator detector. It located 53 km away from both Yangjiang and Taishan Nuclear Power Plants in Guangdong, China. experimental hall, spanning more than 50 meters, under a granite mountain of over 700 m overburden. Within six years running, detection reactor antineutrinos can resolve at confidence level 3-4$\sigma$, oscillation parameters...
Crown roots constitute the majority of rice (Oryza sativa) root system and play an important role in growth development. However, molecular mechanism crown formation is not well understood. Here, we characterized a dominant mutant, enhancer1 (ren1-D), which was observed to exhibit more robust system, increased number, reduced plant height. Molecular genetic analyses revealed that these phenotypes are caused by activation cytokinin oxidase/dehydrogenase (CKX) family gene, OsCKX4. Subcellular...
Pre-harvest sprouting (PHS) or vivipary in cereals is an important agronomic trait that results significant economic loss. A considerable number of mutations cause PHS have been identified several species. However, relatively few viviparous mutants rice (Oryza sativa L.) reported. To explore the mechanism rice, we carried out extensive genetic screening and 12 (phs). Based on their phenotypes, these phs were classified into three groups. Here characterize detail one groups, which contains...
Abstract MicroRNAs and small interfering RNAs (siRNAs) are two classes of regulatory derived from different types precursors processed by distinct Dicer or Dicer-like (DCL) proteins. During evolution, four Arabidopsis thaliana DCLs six rice (Oryza sativa) (Os DCLs) appear to have acquired specialized functions. The well characterized, but those in remain largely unstudied. Here, we show that both knockdown loss function DCL4, the homolog lead vegetative growth abnormalities severe...
Brassinosteroids (BRs) are a class of steroid hormones regulating multiple aspects plant growth, development, and adaptation. Compared with extensive studies in Arabidopsis (Arabidopsis thaliana), the mechanism BR signaling rice (Oryza sativa) is less understood. Here, we identified OsWRKY53, transcription factor involved defense responses, as an important regulator signaling. Phenotypic analyses showed that OsWRKY53 overexpression led to enlarged leaf angles increased grain size, contrast...
Grain size is one of the most important determinants crop yield in cereals. Here, we identified a dominant mutant, big grain2 (bg2-D) from our enhancer-trapping population. Genetic analysis and SiteFinding PCR (polymerase chain reaction) revealed that BG2 encodes cytochrome P450, OsCYP78A13. Sequence search CYP78A13 has paralogue Length 3.2 (GL3.2, LOC_Os03g30420) rice with distinct expression patterns, transgenic plants harbouring either or GL3.2 showed both can promote grain growth....
Chromatin modifications affect flowering time in the long-day plant Arabidopsis thaliana, but role of histone methylation regulation rice (Oryza sativa), a short-day plant, remains to be elucidated. We identified late-flowering long vegetative phase1 (lvp1) mutant and used map-based cloning reveal that lvp1 affects SET domain group protein 724 (SDG724). SDG724 functions as methyltransferase vitro contributes major fraction global H3 lysine 36 (H3K36) vivo. Expression analyses genes wild-type...
Cuticular wax plays crucial roles in protecting plants from environmental stresses, particularly drought stress. Many enzyme-encoding genes and transcription factors involved biosynthesis have been identified, but the underlying posttranslational regulatory mechanisms are poorly understood. Here, we demonstrate that DROUGHT HYPERSENSITIVE (DHS), encoding a Really Interesting New Gene (RING)-type protein, is critical regulator of rice (Oryza sativa). The cuticular contents were significantly...
The contradiction between “high yielding” and “early maturing” hampers further improvement of annual rice yield. Here we report the positional cloning a major maturity duration regulatory gene, Early flowering-completely dominant ( Ef-cd ), demonstrate that natural variation in could be used to overcome above contradictory. locus gives rise long noncoding RNA (lncRNA) antisense transcript overlapping OsSOC1 gene. lncRNA expression positively correlates with H3K36me3 deposition. Field test...
Abstract Low-temperature germination (LTG) is an important agronomic trait for rice ( Oryza sativa ). Japonica generally has greater capacity at low temperatures than the indica subpopulation. However, genetic basis and molecular mechanisms underlying this complex are poorly understood. Here, we report that OsUBC12 , encoding E2 ubiquitin-conjugating enzyme, increases low-temperature germinability in japonica owing to a transposon insertion its promoter enhancing expression. Natural...
Bacillus thuringiensis vegetative insecticidal proteins (Vip) are potential alternatives for B. endotoxins that currently utilized in commercial transgenic insect-resistant crops. Screening a large number of isolates resulted the cloning vip3Ac1. Vip3Ac1 showed high activity against fall armyworm Spodoptera frugiperda and cotton bollworm Helicoverpa zea but very low silkworm Bombyx mori. The host specificity this Vip3 toxin was altered by sequence swapping with previously identified toxin,...
In this study, we characterized the semi-dominant mutant nls1-1D (necrotic leaf sheath 1) of rice, which displays spontaneous lesions, specifically on sheaths, with a developmental pattern. plants also exhibited constitutively activated defense responses, including extensive cell death, excess hydrogen peroxide and salicylic acid (SA) accumulation, up-regulated expressions pathogenesis-related genes, enhanced resistance to bacterial pathogens. Map-based cloning revealed that NLS1 encodes...
Summary It has been shown that seed development is regulated by a network of transcription factors in A rabidopsis including LEC 1 ( LEAFY COTYLEDON 1), L1L 1‐like) and the B3 domain 2, FUS 3 FUSCA 3) ABI ABA ‐ INSENSITIVE 3); however, molecular genetic regulation cereals poorly understood. To understand germination cereals, large‐scale screen was performed using our T– DNA mutant population, germination‐defective1 gd1 ) identified. In addition to severe defect, also shows dwarf phenotype...
Bioactive gibberellins (GAs) are key endogenous regulators of plant growth. Previous work identified ELONGATED UPPERMOST INTERNODE1 (EUI1) as a GA-deactivating enzyme that plays an important role in panicle exsertion from the flag leaf sheath rice (Oryza sativa). However, mechanism regulates EUI1 activity during development is still largely unexplored. In this study, we dominant enclosure mutant regulator eui1 (ree1-D), whose phenotype caused by activation homeodomain-leucine zipper...
Summary Pre‐harvest sprouting ( PHS ) is an unfavorable trait in cereal crops that could seriously decrease grain yield and quality. Although some ‐associated quantitative loci or genes cereals have been reported, the molecular mechanism underlying remains largely elusive. Here, we characterized a rice mutant, phs8 , which exhibits phenotype accompanied by sugary endosperm. Map‐based cloning revealed 8 encodes starch debranching enzyme named isoamylase1. Mutation resulted phytoglycogen...
