Uniform processing and detailed annotation of human, worm fly RNA-sequencing data reveal ancient, conserved features the transcriptome, shared co-expression modules (many enriched in developmental genes), matched expression patterns across development similar extent non-canonical, non-coding transcription; furthermore, are used to create a single, universal model predict gene-expression levels for all three organisms from chromatin at promoter. In this paper modENCODE consortium reports on...
Abstract Grains from cereals contribute an important source of protein to human food, and grain content (GPC) is determinant nutritional quality in cereals. Here we show that the quantitative trait locus (QTL) qPC1 rice controls GPC by regulating synthesis accumulation glutelins, prolamins, globulins, albumins starch. encodes a putative amino acid transporter OsAAP6 , which functions as positive regulator rice, such higher expression correlated with GPC. greatly enhances root absorption...
Grain chalkiness reduces the quality of rice (Oryza sativa) and is a highly undesirable trait for breeding marketing. However, underlying molecular cause remains largely unknown. Here, we cloned F-box gene WHITE-CORE RATE 1 (WCR1), which negatively regulates grain improves in rice. A functional A/G variation promoter region WCR1 generates alleles WCR1A WCR1G, originated from tropical japonica wild Oryza rufipogon, respectively. OsDOF17 transcriptional activator that binds to AAAAG cis-element...
Rice seed storage protein (SSP) is an important source of nutrition and energy. Understanding the genetic basis SSP content mining favorable alleles that control it will be helpful for breeding new improved cultivars. An association analysis was performed to identify underlying genes using 527 diverse Oryza sativa accessions grown in two environments. We identified more than 107 associations five different traits, including contents albumin (Alb), globulin (Glo), prolamin (Pro), glutelin...
Abstract Appearance and taste are important factors in rice ( Oryza sativa ) grain quality. Here, we investigated the scores related eating‐quality traits of 533 diverse cultivars to assess relationships between—and genetic basis of—rice eating‐quality. A genome‐wide association study highlighted Wx gene as major factor underlying variation eating Notably, a novel waxy allele, la , which combined two mutations from b exhibited unique phenotype. Reduced GBSSI activity conferred with both...
Brown planthopper (BPH), Nilaparvata lugens Stål, is the most devastating insect pest in rice-producing areas. Three dominant BPH resistance genes (Bph14, Bph15, Bph18) were pyramided into elite indica rice 9311 and its hybrids using marker-assisted selection. Gene effectiveness was evaluated on basis of seedling adult resistance, honeydew weight survival rate BPH.All three affected growth development antibiotic factors, resulting both resistance. Bph15 had greatest effect conferring to BPH....
Rice blast disease is a major restriction in rice production. That usually managed using chemical pesticides, which are expensive terms of cost and environment hazards. Use blast-resistance genes to develop resistant varieties may therefore be more economical environmentally friendly method for effective control.In this study, we improved the resistance four sterile lines, Y58S, GuangZhan63S (GZ63), C815S HD9802S, by introgression 9 cloned broad-spectrum Pi37, Pit, Pid3, Pigm, Pi36, Pi5,...
Global food security has benefited from the development and promotion of two-line hybrid rice system. Excellent eating quality determines market competitiveness varieties based on achieving fundamental requirements high yield good adaptability. Developing sterile restorer lines with improved for breeding by editing genes clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 is an efficient practical alternative to lengthy laborious process conventional improve quality. We...
Combining ability is a measure for selecting elite parents and predicting hybrid performance in plant breeding. However, the genetic basis of combining remains unclear global view from diverse mating designs lacking. We developed North Carolina II (NCII) population 96 Oryza sativa four male sterile lines to identify greatest value rice production. Statistical analyses indicated that general (GCA) specific (SCA) contributed variously different agronomic traits. In genome-wide association...
Grain size, which encompasses grain length, width, and thickness, is a critical determinant of both weight quality in rice. Despite the extensive regulatory networks known to determine length pathway(s) that regulate thickness remain be clarified. Here, we present map-based cloning characterization qGT3, major quantitative trait locus for rice encodes MADS-domain transcription factor OsMADS1. Our findings demonstrate OsMADS1 regulates by affecting sugar delivery during filling, show...
Chromatin remodeling during sperm maturation could erase epigenetic landmarks on the paternal genome, creating a challenge for its reestablishment fertilization. Here, we show that selective retention of chromosomal protein in mature protects identity telomeres Drosophila . The ms(3)k81 ( k81 ) gene is duplication hiphop encodes telomeric protein. Although HipHop somatic cells, K81 produced exclusively males and localizes to postmitotic including sperm. In embryos fathered by mutants,...
The brown planthopper (BPH), an insect species that feeds on rice plants (Oryza sativa L.), is one of the most destructive pests rice. BPH can be controlled with chemical pesticides, but they are expensive in terms cost and environmental hazards. Hence, utilization resistance genes resistant varieties considered as a more economical eco-friendly effective method for control.In this study, six dominant BPH-resistance (Bph3, Bph14, Bph15, Bph18, Bph20 Bph21) were introduced into elite indica...
Abstract Brown planthopper (BPH) is the most destructive pest of rice in Asia. To date 29 BPH resistance genes have been identified, but only a few are being used breeding due to inefficient markers for marker-assisted selection (MAS) and little knowledge real effects genes. In this study we individually transferred 13 or QTLs ( Bph14 , QBph3 QBph4 Bph17 Bph15 Bph20 Bph24 Bph6 Bph3 Bph9 Bph10 Bph18 Bph21 ) into cultivar 9311 by marker assisted backcross (MABB). Through positive negative...
Grain size is a quantitative trait with complex genetic mechanism, characterized by the combination of grain length (GL), width (GW), to ration (LWR), and thickness (GT). In this study, we conducted loci (QTL) analysis investigate basis using BC1F2 BC1F2:3 populations derived from two indica lines, Guangzhan 63-4S (GZ63-4S) TGMS29 (core germplasm number W240). A total twenty-four QTLs for were identified, among which, three (qGW1, qGW7, qGW12) controlling GL (qGW5 qGL9) GW validated...
Abstract Background Rice blast is an economically important and mutable disease of rice. Using host resistance gene to breed resistant varieties has been proven be the most effective economical method control rice new genes or quantitative trait loci (QTLs) are then needed. Results In this study, we constructed two advanced backcross population mapping QTLs. CR071 QingGuAi3 were as donor parent establish BC 3 F 1 derived 2 in Jin23B background. By challenging populations with natural...
Quality is a complex trait that not only the key determinant of market value rice grain, but also major constraint in breeding. It influenced by both genetic and environmental factors. However, combined effects genotypes factors on grain quality remain unclear. In this study, we used three-factor experimental design to examine different Wx grown under nitrogen fertilization temperature conditions during development. We found three contributed differently taste, appearance, nutritional...
