Sorghum, an African grass related to sugar cane and maize, is grown for food, feed, fibre fuel. We present initial analysis of the ∼730-megabase Sorghum bicolor (L.) Moench genome, placing ∼98% genes in their chromosomal context using whole-genome shotgun sequence validated by genetic, physical syntenic information. Genetic recombination largely confined about one-third sorghum genome with gene order density similar those rice. Retrotransposon accumulation recombinationally recalcitrant...
Correlated gene arrangements among taxa provide a valuable framework for inference of shared ancestry genes and the utilization findings from model organisms to study less-well-understood systems. In angiosperms, comparisons are complicated by recurring polyploidy extensive genome rearrangement. New sequences improved analytical approaches clarifying angiosperm evolution revealing patterns differential loss after duplication retention associated with some morphological complexity. Because...
In the early 1990s an outbreak of papaya ringspot virus (PRSV) in groves Puna district Hawaii caused severe damage to important crop. Since then, planting two transgenic cultivars resistant — called 'SunUp' and 'Rainbow' has helped maintain yields. SunUp is a red-fleshed fruit that expresses coat protein gene mild mutant PRSV, conferring resistance via post-transcriptional silencing. Rainbow yellow-fleshed (and therefore more popular) F1 hybrid bred from SunUp. Now draft genome sequence...
The draft genome of the pear ( Pyrus bretschneideri ) using a combination BAC-by-BAC and next-generation sequencing is reported. A 512.0-Mb sequence corresponding to 97.1% estimated size this highly heterozygous species assembled with 194× coverage. High-density genetic maps comprising 2005 SNP markers anchored 75.5% all 17 chromosomes. encodes 42,812 protein-coding genes, these, ∼28.5% encode multiple isoforms. Repetitive sequences 271.9 Mb in length, accounting for 53.1% genome, are...
Large-scale (segmental or whole) genome duplication has been recurring in angiosperm evolution. Subsequent gene loss and rearrangements further affect copy numbers fractionate ancestral linkages across multiple chromosomes. The fragmented "multiple-to-multiple" correspondences resulting from this distinguishing feature of evolution complicates comparative genomic studies. Using a robust computational framework that combines information orthologous duplicated regions to construct local...
Coffee, tea, and chocolate converge Caffeine has evolved multiple times among plant species, but no one knows whether these events involved similar genes. Denoeud et al. sequenced the Coffea canephora (coffee) genome identified a conserved gene order (see Perspective by Zamir). Although this species underwent fewer duplications than related relevant caffeine genes experienced tandem that expanded their numbers within species. Scientists have seen independent expansions in distantly of tea...
Ray Ming, Robert Paull, Qingyi Yu and colleagues report the genome sequences of two cultivated pineapple varieties one wild relative. Their analysis supports use as a reference for monocot comparative genomics provides insight into evolution crassulacean acid metabolism photosynthesis. Pineapple (Ananas comosus (L.) Merr.) is most economically valuable crop possessing (CAM), photosynthetic carbon assimilation pathway with high water-use efficiency, second important tropical fruit. We...
High oil and protein content make tetraploid peanut a leading food legume. Here we report high-quality genome sequence, comprising 2.54 Gb with 20 pseudomolecules 83,709 protein-coding gene models. We characterize functional groups implicated in seed size evolution, content, disease resistance symbiotic nitrogen fixation. The B subgenome has more genes general expression dominance, temporally associated long-terminal-repeat expansion the A that also raises questions about A-genome...
In addition to the genomes of Arabidopsis (Arabidopsis thaliana) and poplar (Populus trichocarpa), two near-complete rosid genome sequences, grape (Vitis vinifera) papaya (Carica papaya), have been recently released. The phylogenetic relationship among these four placement their three independent, fractionated tetraploidies sum a powerful comparative genomic system. CoGe, platform multiple whole or provides an integrative Web-based system find align syntenic chromosomal regions visualize...
Abstract The ordering and orientation of genomic scaffolds to reconstruct chromosomes is an essential step during de novo genome assembly. Because this process utilizes various mapping techniques that each provides independent line evidence, a combination multiple maps can improve the accuracy resulting chromosomal assemblies. We present ALLMAPS, method capable computing scaffold maximizes colinearity across collection maps. ALLMAPS robust against common errors, generates sequences are...
Abstract Background Sacred lotus is a basal eudicot with agricultural, medicinal, cultural and religious importance. It was domesticated in Asia about 7,000 years ago, cultivated for its rhizomes seeds as food crop. particularly noted 1,300-year seed longevity exceptional water repellency, known the effect. The latter property due to nanoscopic closely packed protuberances of self-cleaning leaf surface, which have been adapted manufacture industrial paint, Lotusan. Results genome China...
Sex determination in papaya is controlled by a recently evolved XY chromosome pair, with two slightly different Y chromosomes controlling the development of males (Y) and hermaphrodites (Y h ). To study events early sex evolution, we sequenced hermaphrodite-specific region (HSY) its X counterpart, yielding an 8.1-megabase (Mb) HSY pseudomolecule, 3.5-Mb sequence for corresponding region. The larger than region, mostly due to retrotransposon insertions. differs from large-scale inversions,...
The vast majority of eukaryotic organisms reproduce sexually, yet the nature sexual system and mechanism sex determination often vary remarkably, even among closely related species. Some species animals plants change across their lifespan, some contain hermaphrodites as well males females, determine with highly differentiated chromosomes, while others according to environment. Testing evolutionary hypotheses regarding causes consequences this diversity requires interspecific data placed in a...
Abstract Tea is an important global beverage crop and largely clonally propagated. Despite previous studies on the species, its genetic evolutionary history deserves further research. Here, we present a haplotype-resolved assembly of Oolong tea cultivar, Tieguanyin. Analysis allele-specific expression suggests potential mechanism in response to mutation load during long-term clonal propagation. Population genomic analysis using 190 Camellia accessions uncovered independent histories parallel...
Abstract Lychee is an exotic tropical fruit with a distinct flavor. The genome of cultivar ‘Feizixiao’ was assembled into 15 pseudochromosomes, totaling ~470 Mb. High heterozygosity (2.27%) resulted in two complete haplotypic assemblies. A total 13,517 allelic genes (42.4%) were differentially expressed diverse tissues. Analyses 72 resequenced lychee accessions revealed independent domestication events. extremely early maturing cultivars preferentially aligned to one haplotype domesticated...
Abstract To date, little is known about the evolution of fern genomes, with only two small genomes published from heterosporous Salviniales. Here we assembled genome Alsophila spinulosa , as flying spider-monkey tree fern, onto 69 pseudochromosomes. The remarkable preservation synteny, despite resulting an ancient whole-genome duplication over 100 million years ago, unprecedented in plants and probably speaks to uniqueness ferns. Our detailed investigations into stem anatomy lignin...
