Abstract Low temperature is a major factor limiting rice productivity and geographical distribution. Improved cold tolerance expanded cultivation to high-altitude or high-latitude regions would help meet growing demand. Here we explored QTL for cloned the gene, CTB4a (cold at booting stage), encoding conserved leucine-rich repeat receptor-like kinase. We show that different alleles confer distinct levels of selection variation in promoter region has occurred on basis environmental...
Abstract Upland rice is a distinct ecotype that grows in aerobic environments and tolerates drought stress. However, the genetic basis of its resistance unclear. Here, using an integrative approach combining genome-wide association study with analyses introgression lines transcriptomic profiles, we identify gene, DROUGHT1 ( DROT1 ), encoding COBRA-like protein confers rice. specifically expressed vascular bundles directly repressed by ERF3 activated ERF71, both drought-responsive...
Grain size, one of the important components determining grain yield in rice, is controlled by multiple quantitative trait loci (QTLs). Intensive artificial selection for size during domestication evidenced modern cultivars compared to their wild relatives. Here, we report molecular cloning and characterization OsLG3b, a QTL length tropical japonica rice that encodes MADS-box transcription factor 1 (OsMADS1). Six SNPs OsLG3b region led alternative splicing, which were associated with an...
Floral organs in rice (Oryza sativa) can be purple, brown, or red color due to the accumulation of flavonoids, but molecular mechanism underlying specific organ pigmentation is not clear. Here, we propose a C–S–A gene model for hull and characterize it through genetic, molecular, metabolomic approaches. Furthermore, conducted phylogenetic studies reveal evolution color. In this system, C1 encodes R2R3-MYB transcription factor acts as color-producing gene, S1 bHLH protein that functions...
Grain length is one of the determinants yield in rice and auxin plays an important role regulating it by mediating cell growth. Although several genes pathway are involved grain length, underlying molecular mechanisms remain unclear. In this study we identify a RING-finger wd40-associated ubiquitin-like (RAWUL) domain-containing protein, Gnp4/LAX2, with hitherto unknown regulation its influence on expansion. Gnp4/LAX2 broadly expressed plant subcellular localization analysis shows that...
Drought is a major factor restricting the production of rice (Oryza sativa L.). The identification natural variants for drought stress-related genes an important step toward developing genetically improved varieties. Here, we characterized member SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) family, OsSPL10, as transcription involved in regulation tolerance rice. OsSPL10 appears to play vital role by controlling reactive oxygen species (ROS) and stomatal movements. Haplotype allele frequency...
Summary A strong root system facilitates the absorption of water and nutrients from soil, to improve growth crops. However, date, there are still very few development regulatory genes that can be used in crop breeding for agriculture. In this study, we cloned a negative regulator gene development, Robust Root System 1 ( RRS1 ), which encodes an R2R3‐type MYB family transcription factor. knockout plants showed enhanced growth, including longer length, lateral larger density. represses by...
Higher chlorophyll content (CC) and strong stay-green (SG) traits are conducive for improvement of photosynthetic efficiency in plants. Exploration natural elite alleles CC SG, highly resolved gene haplotypes beneficial to rational design breeding high-photosynthetic efficiency. Phenotypic analysis 368 rice accessions showed no significant correlation between higher stronger SG japonica than indica. Genome-wide association studies six indices identified a large number signals, among which 14...
Lodging reduces grain yield and quality in cereal crops. resistance is affected by the strength of culm, which influenced culm diameter, wall thickness, cell composition. To explore genetic architecture diameter rice (Oryza sativa), we conducted a genome-wide association study (GWAS). We identified STRONG CULM 2 (STRONG2), encodes mannan synthase CSLA5, showed that plants overexpressed this gene had increased improved lodging resistance. STRONG2 appears to increase levels components, such as...
SUMMARY Plant height and flag leaf morphology critically affect plant yield because they determine above‐ground biomass photosynthate production. However, few genetic basis analyses gene mining studies on height, length, width have been performed, there is little available information about the evolution utilization of underlying natural alleles. This study conducted a genome‐wide association (GWAS) using 689 rice accessions collected from diverse regions across globe. The GWAS identified...
Summary Yield in rice is determined mainly by panicle architecture. Using map‐based cloning, we identified an R2R3 MYB transcription factor REGULATOR OF GRAIN NUMBER1 (RGN1) affecting grain number and Mutation of RGN1 caused absence lateral grains on secondary branches. We demonstrated that controls formation regulation LONELY GUY ( LOG ) expression, thus controlling shaping A novel favourable allele, C , derived from the Or‐I group wild affected architecture means longer panicles....
Anthocyanins accumulate in various organs of rice, and the regulatory genes involved pigmentation specific organs, such as pericarp, hull, leaf, apiculus, stigma have been elucidated. However, corresponding gene for rice culm has not clarified. The well-known MYB-bHLH-WD40 (MBW) complex plays vital role regulating anthocyanin biosynthesis pathway plants. core members MBW hierarchical regulation between these are fully elucidated rice. Here, by map-based cloning, we identified culm-specific
Rice (Oryza sativa L.) cultivars harbour morphological and physiological traits different from those of wild rice (O. rufipogon Griff.), but the molecular mechanisms underlying domestication remain controversial. Here, we show that awn long grain in near-isogenic NIL-GLA are separately controlled by variations within GLA (Grain Length Awn Development) gene, a new allele GAD1/RAE2, which encodes one member EFPL (epidermal patterning factor-like protein) family. Haplotype analyses transgenic...
The yield of rice is mostly affected by three factors, namely, panicle number, grain number and weight. Variation in numbers mainly caused tiller branches generated from axillary meristems (AMs). MOC1 encodes a putative GRAS family nuclear protein that regulates AM formation. Although several alleles have been identified, its variation germplasm resources remains unclear. In the present study we characterized novel moc1 allele named gnp6 which has thymine insertion coding sequence SAW motif...
Summary Upland rice is a distinctive drought‐aerobic ecotype of cultivated highly resistant to drought stress. However, the genetic and genomic basis for adaptation upland remains largely unclear due lack resources. In this study, we identified 25 typical accessions assembled high‐quality genome one varieties, IRAT109, comprising 384 Mb with contig N50 19.6 Mb. Phylogenetic analysis revealed lowland have distinct differentiation within japonica subgroup. Comparative analyses that adaptive...
To dissect the genetic mechanism of multi-seed pod in peanut, we explored QTL/gene controlling and analyzed interaction effect QTL environment. Two hundred forty eight recombinant inbred lines (RIL) from cross Silihong × Jinonghei 3 were used as experimental materials planted 8 environments 2012 to 2017. Three methods analysis performed. These included individual environment analysis, joint multiple environments, epistatic for QTL. Phenotypic data best linear unbiased prediction (BLUP) value...
There is a lot of research in genetic algorithm about structural optimization. But as far the large multi-goal program concerned, it limits application for reason its specialty and calculation. In order to explore new resolution, author proposed combining optimization, which based on gradient algorithm. Gradient used superpose, result got improve herd The superior compared with root best point chosen be incipient next step super position. This method can keep course also speed up searching,...
Flavonoids have anti-inflammatory, antioxidative, and anticarcinogenic effects. Breeding rice varieties rich in flavonoids can prevent chronic diseases such as cancer cardio-cerebrovascular diseases. However, most of the genes reported are known to regulate flavonoid content leaves or seedlings. To further elucidate genetic basis grains identify germplasm grains, a set core collections containing 633 accessions from 32 countries was used determine total (TFC) brown rice. We identified ten...
