Most agriculturally important traits are regulated by genes known as quantitative trait loci (QTLs) derived from natural allelic variations. We here show that a QTL increases grain productivity in rice, Gn1a, is gene for cytokinin oxidase/dehydrogenase (OsCKX2), an enzyme degrades the phytohormone cytokinin. Reduced expression of OsCKX2 causes accumulation inflorescence meristems and number reproductive organs, resulting enhanced yield. pyramiding to combine plant height same genetic...
Crop domestications are long-term selection experiments that have greatly advanced human civilization. The domestication of cultivated rice (Oryza sativa L.) ranks as one the most important developments in history. However, its origins and processes controversial long been debated. Here we generate genome sequences from 446 geographically diverse accessions wild species Oryza rufipogon, immediate ancestral progenitor rice, 1,083 indica japonica varieties to construct a comprehensive map...
The next-generation sequencing technology coupled with the growing number of genome sequences opens opportunity to redesign genotyping strategies for more effective genetic mapping and analysis. We have developed a high-throughput method recombinant populations utilizing whole-genome resequencing data generated by Illumina Genome Analyzer. A sliding window approach is designed collectively examine genome-wide single nucleotide polymorphisms genotype calling recombination breakpoint...
Tillering in rice (Oryza sativa) is one of the most important agronomic traits that determine grain yields. Previous studies on tillering mutants have shown outgrowth tiller buds regulated by a carotenoid-derived MAX/RMS/D (more axillary branching) pathway, which may be conserved higher plants. Strigolactones, group terpenoid lactones, been recently identified as products pathway inhibits bud outgrowth. We report here molecular genetic characterization d27, classic mutant exhibiting...
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...
Grain size and shape are important components determining rice grain yield, they controlled by quantitative trait loci (QTLs). Here, we report the cloning functional characterization of a major length QTL, qGL3 , which encodes putative protein phosphatase with Kelch-like repeat domain (OsPPKL1). We found rare allele qgl3 that leads to long phenotype an aspartate-to-glutamate transition in conserved AVLDT motif second Kelch OsPPKL1. The genome has other two OsPPKL1 homologs, OsPPKL2 OsPPKL3 ....
Plant mechanical strength is an important agronomic trait. To understand the molecular mechanism that controls plant of crops, we characterized classic rice mutant brittle culm1 (bc1) and isolated BC1 using a map-based cloning approach. BC1, which encodes COBRA-like protein, expressed mainly in developing sclerenchyma cells vascular bundles rice. In these types cells, mutations cause not only reduction cell wall thickness cellulose content but also increase lignin level, suggesting gene...
Abstract Brassinosteroid (BR) and gibberellin (GA) are two predominant hormones regulating plant cell elongation. A defect in either of these leads to reduced growth dwarfism. However, their relationship remains unknown rice (Oryza sativa). Here, we demonstrated that BR regulates elongation by modulating GA metabolism rice. Under physiological conditions, promotes accumulation the expression metabolic genes stimulate greatly induces D18/GA3ox-2, one biosynthetic genes, leading increased GA1...
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...
In Arabidopsis thaliana, the GSK3/SHAGGY-like kinase BRASSINOSTEROID-INSENSITIVE2 (BIN2) plays a critical role in brassinosteroid (BR) signaling pathway by negatively regulating activities of bri1-EMS-SUPPRESSOR1/BRASSINAZOLE-RESISTANT1 family transcription factors that regulate expression downstream BR-responsive genes. this study, we analyzed function rice (Oryza sativa) (GSK2), which is one orthologs BIN2. Overexpression GSK2 (Go) led to plants with typical BR loss-of-function phenotypes,...
IDEAL PLANT ARCHITECTURE1 (IPA1) is critical in regulating rice (Oryza sativa) plant architecture and substantially enhances grain yield. To elucidate its molecular basis, we first confirmed IPA1 as a functional transcription activator then identified 1067 2185 genes associated with binding sites shoot apices young panicles, respectively, through chromatin immunoprecipitation sequencing assays. The SQUAMOSA PROMOTER BINDING PROTEIN-box direct core motif GTAC was highly enriched peaks;...
