Global warming is a major abiotic stress factor, which limit rice production. Exploiting the genetic basis of natural variation in heat resistance at different reproductive stages among diverse exotic Oryza germplasms can help breeding heat-resistant cultivars. Here, we identified stable quantitative trait locus (QTL) for tolerance heading stage on chromosome 5 (qHTH5) O. rufipogon Griff. The corresponding gene, HTH5, pertains to pyridoxal phosphate-binding protein PLPBP (formerly called...
Low temperature is an environmental stress factor that always been applied in research on improving crop growth, productivity, and quality of crops. Polyunsaturated fatty acids (PUFAs) play important role cold tolerance, so its genetic manipulation the PUFA contents crops has led to modification sensitivity. In this study, we over-expressed ω-3 acid desaturase from Glycine max (GmFAD3A) drove by a maize ubiquitin promoter rice. Compared wild type (ZH11), ectopic expression GmFAD3A increased...
Wild species of crops serve as a valuable germplasm resource for breeding modern cultivars. Rice (Oryza sativa L.) is vital global staple food. However, research on genome evolution and diversity wild rice remains limited. Here, we present nearly complete genomes 13 representative species. By integrating with four previously published pangenome analysis, total 101,723 gene families are identified across the genus, including 9834 (9.67%) core families. Additionally, 63,881 absent in...
Abstract Background Drought is global environmental stress that limits crop yields. Plant-associated microbiomes play a crucial role in determining plant fitness response to drought, yet the fundamental mechanisms for maintaining microbial community stability under drought disturbances wild rice are poorly understood. We make explicit comparisons of leaf, stem, root and rhizosphere from drought-tolerant ( Oryza longistaminata ) stress. Results find microbiome was divided into...
High soils salinity is a main factor affecting agricultural production. Studying the function of salt-tolerance-related genes essential to enhance crop tolerance stress. Rab7 small GTP-binding protein that distributed widely among eukaryotes. Endocytic trafficking mediated by plays an important role in animal and yeast cells, but current understanding plants still very limited. Herein, we isolated vesicle gene, OsRab7 , from rice. Transgenic rice over-expressing exhibited enhanced seedling...
The ubiquitin 26S proteasome system (UPS) is critical for enabling plants to alter their proteomes integrate internal and external signals the photoperiodic induction of flowering. We previously demonstrated that HAF1, a C3HC4 RING domain-containing E3 ligase, essential precisely modulate timing Heading Date1 accumulation ensure appropriate responses under short-day conditions in rice (Oryza sativa). However, how HAF1 mediates flowering long-day remains unknown. In this study, we show OsELF3...
D1-cytoplasmic male sterility (CMS) rice is a sporophytic cytoplasmic male-sterile developed from Dongxiang wild that exhibits no-pollen-grain phenotype. A mitochondrial chimeric gene (orf182) was detected by genome sequencing and comparative analysis. Orf182 composed of three recombinant fragments, the largest which homologous to Sorghum bicolor sequences. In addition, orf182 found only in species collected China. Northern blot analysis showed transcripts were affected Rf genes...
Compared with root-associated habitats, little is known about the role of microbiota inside other rice organs, especially rhizome perennial wild rice, and this information may be importance for agriculture. Oryza longistaminata various agronomically valuable traits, including large biomass on poor soils, high nitrogen use efficiency, resistance to insect pests disease. Here, we compared endophytic bacterial archaeal communities network structures compartments O . using 16S rRNA gene...
Abstract Background Cytoplasmic male sterility (CMS) has greatly improved the utilization of heterosis in crops due to absence functional gametophyte. The newly developed sporophytic D1 type CMS (CMS-D1) rice exhibits unique characteristics compared well-known CMS-WA line, making it a valuable resource for breeding. Results In this research, novel CMS-D1 line named Xingye A (XYA) was established, characterized by small, transparent, and shriveled anthers. Histological terminal...
The growth of all methanogens is limited to a specific temperature range. However, Methanothermobacter thermautotrophicus can be found in variety natural and artificial environments, the temperatures which sometimes even exceed ranges thermophiles. As result, extent methane production survival are affected by remains unclear. To investigate mechanisms methanogenesis that Archaea have evolved cope with drastic shifts, responses were investigated under high (71°C) cold shock (4°C) using...
Cytoplasmic male sterility (CMS) has often been associated with abnormal mitochondrial open frames (ORF), orfH79 is a chimeric gene responsible for the CMS trait in Honglian (HL) rice. In this study, weakly produced ORFH79 protein significantly inhibited growth of E. coli an oxygen culture, however, transformants producing was indistinguishable from control under anaerobic incubation conditions. addition, lower respiration rate, wrinkled bacterial surfaces, and decreased pyruvate kinase...
The landraces preserved by indigenous worldwide exhibited larger variation in the phenotypes and adaption to different environments, which suggests that they comprise rich resources can be served as a gene pool for rice improvement. Despite extensive studies on cultivated rice, variations relationships between modern remain unclear. In this study, total of 20 varieties include 10 Oryza javanica collected from countries indica China were genotyped yielded sum 99.9-Gb resequencing raw data....
Oryza sativa ssp. javanica rice varieties exhibit a wide variation in the phenotypes of several important agronomic traits, including grain quality, shape, plant architecture, disease resistance, and high adaption to an unfavorable environment, indicating great potential for improvement. DNA molecular markers are basic critical tools genetic analysis gene mining. However, only few whole-genome analyses have been performed Javanica (tropical japonica rice), this has hampered utilization such...
Abstract Background Drought is a global environmental stress that limits crop yields. Microbial communities control many biogeochemical processes, and predictive understanding of how microbial assemble in response to drought central addressing the challenges caused by drought. Little known about microbiome assembly processes rice-ecosystems, particularly with regard their adaptation. Wild rice may serve as source superior tolerance candidate for breeding. There an urgent need explore wild...
