It is generally believed that maize ( Zea mays L. ssp. ) arose as a tetraploid; however, the two progenitor genomes cannot be unequivocally traced within genome of modern maize. We have taken new approach to investigate origin genome. isolated and sequenced large genomic fragments from regions surrounding five duplicated loci their orthologous in sorghum, then we compared these sequences with rice Within studied segments, identified 11 genes were conserved location, order, orientation....
Abstract Background Characterization of genetic variations in maize has been challenging, mainly due to deterioration collinearity between individual genomes the species. An international consortium research groups combined resources develop haplotype version 3 (HapMap 3), built from whole-genome sequencing data 1218 lines, covering predomestication and domesticated Zea mays varieties across world. Results A new computational pipeline was set up process more than 12 trillion bp data, a...
Abstract Maize is an important crop with a high level of genome diversity and heterosis. The sequence typical female line, B73, was previously released. Here, we report de novo assembly corresponding male representative Mo17. More than 96.4% the 2,183 Mb assembled can be accounted for by 362 scaffolds in ten pseudochromosomes 38,620 annotated protein-coding genes. Comparative analysis revealed large gene-order gene structural variations: approximately 10% genes were mutually nonsyntenic,...
Abstract Maize (Zea mays) is an excellent cereal model for research on seed development because of its relatively large size both embryo and endosperm. Despite the importance in agriculture, genome-wide transcriptome pattern throughout has not been well characterized. Using high-throughput RNA sequencing, we developed a spatiotemporal atlas B73 maize based 53 samples from fertilization to maturity embryo, endosperm, whole tissues. A total 26,105 genes were found be involved programming...
Soil salinity is one of several major abiotic stresses that constrain maize productivity worldwide. An improved understanding salt-tolerance mechanisms will thus enhance the breeding salt-tolerant and boost productivity. Previous studies have indicated maintenance leaf Na+ concentration essential for salt tolerance, difference in exclusion has previously been associated with variation tolerance between varieties. Here, we report identification functional characterization a quantitative trait...
Significance Helitrons are unusual rolling-circle eukaryotic transposons with a remarkable ability to capture gene sequences, which makes them of considerable evolutionary importance. Because lack typical transposon features, they challenging identify and estimated comprise at most 2% sequenced genomes. Here, we describe HelitronScanner, generalized tool for their identification based on motif-extracting algorithm proposed initially in study natural languages. HelitronScanner overcomes the...
Ustilaginoidea virens (Cooke) Takah is an ascomycetous fungus that causes rice false smut, a devastating emerging disease worldwide. Here we report 39.4 Mb draft genome sequence of U. encodes 8,426 predicted genes. The has ~25% repetitive sequences have been affected by repeat-induced point mutations. Evolutionarily, close to the entomopathogenic Metarhizium spp., suggesting potential host jumping across kingdoms. possesses reduced gene inventories for polysaccharide degradation, nutrient...
Drought is one of the major factors limiting global maize production. Exposure to long-term drought conditions inhibits growth and leads yield losses. Although several drought-responsive genes have been identified functionally analyzed, mechanisms underlying responses water recovery treatments not fully elucidated. To characterize how seedling respond stress at transcriptional level, we analyzed physiological differentially expressed (DEGs) in inbred line B73 under deficit conditions.The...
The early maize (Zea mays) seed undergoes several developmental stages after double fertilization to become fully differentiated within a short period of time, but the genetic control this highly dynamic and complex process remains largely unknown. Here, we report high temporal-resolution investigation transcriptomes using 31 samples collected at an interval 4 or 6 h first six days development. These time-course were clearly separated into four distinct groups corresponding fertilization,...
Abstract A complete telomere-to-telomere (T2T) finished genome has been the long pursuit of genomic research. Through generating deep coverage ultralong Oxford Nanopore Technology (ONT) and PacBio HiFi reads, we report here a assembly maize with each chromosome entirely traversed in single contig. The 2,178.6 Mb T2T Mo17 base accuracy over 99.99% unveiled structural features all repetitive regions genome. There were several super-long simple-sequence-repeat arrays having consecutive...
Abstract Setaria italica (foxtail millet), a founder crop of East Asian agriculture, is model plant for C4 photosynthesis and developing approaches to adaptive breeding across multiple climates. Here we established the pan-genome by assembling 110 representative genomes from worldwide collection. The composed 73,528 gene families, which 23.8%, 42.9%, 29.4% 3.9% are core, soft dispensable private genes, respectively; 202,884 nonredundant structural variants were also detected....
Maize (Zea mays) originated in tropical areas and is thus susceptible to low temperatures, which pose a major threat maize production. Our understanding of the molecular basis cold tolerance limited. Here, we identified bZIP68, basic leucine zipper (bZIP) transcription factor, as negative regulator maize. Transcriptome analysis revealed that bZIP68 represses cold-induced expression DREB1 factor genes. The stability transcriptional activity are controlled by its phosphorylation at conserved...
