More than half of the world's population uses rice as a source carbon intake every day. Improving grain quality is thus essential to consumers. The three main properties that determine eating and cooking quality--amylose content, gel consistency, gelatinization temperature--correlate with one another, but underlying mechanism these remains unclear. Through an association analysis approach, we found genes related starch synthesis cooperate each other form fine regulating network controls...
Abstract The indica and japonica rice ( Oryza sativa ) subspecies differ in nitrate (NO 3 − assimilation capacity nitrogen (N) use efficiency (NUE). Here, we show that a major component of this difference is conferred by allelic variation at OsNR2 , gene encoding NADH/NADPH-dependent NO reductase (NR). Selection-driven divergence has resulted variant alleles structurally distinct proteins, with exhibiting greater NR activity. Indica also promotes uptake via feed-forward interaction OsNRT1.1B...
The architecture of the rice inflorescence, which is determined mainly by number and length primary secondary inflorescence branches, importance in both agronomy developmental biology. position branches are established during phase transition from vegetative to reproductive growth, several genes identified as participating this process do so regulating meristemic activities inflorescence. However, little known about molecular mechanism that controls branch elongation. Here, we report on a...
Summary Although grain size is one of the most important components yield, little information known about mechanisms that determine final in crops. Here we characterize rice small grain1 ( smg1 ) mutants, which exhibit and light grains, dense erect panicles comparatively slightly shorter plants. The short panicle phenotypes mutants are caused by a defect cell proliferation. mutations were identified, using map‐based cloning approach, mitogen‐activated protein kinase 4 Os MKK ). Relatively...
Abstract Lignin content and composition are two important agronomic traits for the utilization of agricultural residues. Rice (Oryza sativa) gold hull internode phenotype is a classical morphological marker trait that has long been applied to breeding genetics study. In this study, we have cloned GOLD HULL AND INTERNODE2 (GH2) gene in rice using map-based cloning approach. The result shows gh2 mutant lignin-deficient mutant, GH2 encodes cinnamyl-alcohol dehydrogenase (CAD). Consistent with...
Significance Hybrid rice developed in China has been contributing greatly to the world’s food production. The pioneer super hybrid by crossing 93–11 and Peiai 64s , Liang–You–Pei–Jiu widely grown other Asia-Pacific regions for its high yield. Here, quality genome sequences both parental lines were presented updated, a high-resolution map of genome-wide graphic genotypes was constructed deep resequencing core population 132 recombinant inbred lines. A series yield-associated loci fine-mapped,...
The basic premise of high yield in rice is to improve leaf photosynthetic efficiency and coordinate the source–sink relationship plants. Quantitative trait loci (QTLs) related morphological traits chlorophyll content leaves were detected at stages heading maturity, a major QTL (qLSCHL4) flag shape was both recombinant inbred lines constructed using indica cultivar 93-11 japonica Nipponbare. Map-based cloning expression analysis showed that LSCHL4 allelic NAL1, gene previously reported narrow...
Chlorophyll (Chl) b is a ubiquitous accessory pigment in land plants, green algae, and prochlorophytes. This synthesized from Chl by chlorophyllide oxygenase plays key role adaptation to various environments. study characterizes rice mutant, pale leaf (pgl), isolates the gene PGL using map-based cloning approach. PGL, encoding 1, mainly expressed chlorenchyma activated light-dependent synthesis process. Compared with wild-type pgl exhibits lower content reduced disorderly thylakoid...
Understanding the genetic basis of natural variation in grain size among diverse rice varieties can help breeders develop high-yielding cultivars. Here, we report discovery qTGW2, a new semidominant quantitative trait locus for width and weight. The corresponding gene, TGW2, encodes CELL NUMBER REGULATOR 1 (OsCNR1) localized to plasma membrane. A single nucleotide polymorphism (SNP) 1818 bp upstream TGW2 is responsible its different expression, leading alteration weight by influencing cell...
The flag leaf and grain belong to the source sink, respectively, of cereals, both have a bearing on final yield. Premature senescence significantly reduces photosynthetic rate severely lowers crop Cytokinins play important roles in determine number. Here, we characterized rice (Oryza sativa L.) cytokinin oxidase/dehydrogenase OsCKX11 delaying senescence, increasing number, coordinately regulating sink. was predominantly expressed roots, leaves, panicles strongly induced by abscisic acid...
Abstract Nitrogen (N) is a macronutrient that boosts carbon (C) metabolism and plant growth leading to biomass accumulation. The molecular connection between nitrogen utilization efficiency (NUE) production remains unclear. Here, via quantitative trait loci analysis map-based cloning, we reveal natural variation at the MYB61 locus leads differences in N use cellulose biogenesis indica japonica subspecies of rice. , transcriptional factor regulates synthesis, directly regulated by known NUE...
Seedling emergence in monocots depends mainly on mesocotyl elongation, requiring coordination between developmental signals and environmental stimuli. Strigolactones (SLs) karrikins are butenolide compounds that regulate various processes; both able to negatively rice (Oryza sativa) elongation the dark. Here, we report a karrikin signaling complex, DWARF14-LIKE (D14L)-DWARF3 (D3)-O. sativa SUPPRESSOR OF MAX2 1 (OsSMAX1) mediates regulation of We demonstrate D14L recognizes signal recruits...
