Furthermore, phylogenetic analyses under different distances and various levels of missing data (from 10% to 60% of 276 pairwise comparisons of 24 populations) did not change our conclusion (supplementary figs.

In the MO model, outlier sites would group populations either by species or by geography; whereas the neutral and linked sites would produce a phylogenetic pattern in which populations are clustered by geography rather than by species (Roda et al. We tested the neutrality of all 20 loci in our samples using Tajima’ D (Tajima 1989) and Fu and Li’s D* and F* (Fu and Li 1993). 2012; Liu et al. 2011). Nolte Griff Nr. Stärke: GlasGestaltungselement (GF) We demonstrated that O. nivara originated multiple times from different O. rufipogon populations and revealed that different O. nivara populations have evolved similar phenotypes under divergent selection, a reflection of recurrent local adaptation of ancient O. rufipogon populations to dry habitats. performed the common garden experiments in Guangxi. The occurrence of parallel evolution, or the repetition of evolutionary changes in similar environments strongly implicates the action of natural selection in biological diversification because random genetic drift is unlikely to generate such a pattern (Rundle et al. Principal coordinate analysis (PCoA) based on these sequences also indicated that all the samples were organized into two distinct groups that corresponded to their geographic origins rather than their species identity (fig. 218-637-8000 Jenelah Hirtz. The wild rice Oryza rufipogon and O. nivara offer a unique opportunity for studying adaptive divergence and ecological speciation (Sang and Ge 2007; Zheng and Ge 2010). A maximum likelihood (ML) tree of single genes was also constructed using the RAxML program (Stamatakis 2014), which were used to generate estimated species-tree by using ASTRAL (Mirarab et al. As a perennial, O. rufipogon is widely distributed throughout southern China, South and Southeast Asia, Papua New Guinea, and northern Australia, and grows in areas with year-round water, such as swamps and lakes; whereas O. nivara is an annual found within a more restricted distribution in South and Southeast Asia and usually inhabits ponds and swamps that dry up completely during the dry season (Sharma and Shastry 1965; Morishima et al. We performed whole-genome resequencing of pooled samples (Pool-Seq) for 15 O. rufipogon and 9 O. nivara populations (fig. 2015). The species differences were standardized to the smaller value of the two species and thus the scale represents the relative difference between species for individual traits. 2007; Zheng and Ge 2010). S12, Supplementary Material online), and the result should match the observed summary statistics if the model fits our data. Patton Dorothy, C/O Kate Link 101 Delaware Ave Apt, Oakmont, PA 15139. Butlin RK, Saura M, Charrier G, Jackson B, André C, Caballero A, Coyne JA, Galindo J, Grahame JW, Hollander J, Schematic diagram and test for single origin (SO) and multiple origin (MO) models. 1992; Zheng and Ge 2010; Banaticla-Hilario et al. GlasGestaltungselement (GF) 2d and supplementary fig. This study demonstrates an unequivocal case of parallel speciation in plants, in which all four criteria for parallel speciation are satisfied. S7, middle and bottom panels, Supplementary Material online). Our study thus demonstrates a convincing case of parallel ecological speciation as a consequence of adaptation to new environments. Seedlings were transplanted into soil cultures until the trefoil stage and then were planted in buckets (32 cm in diameter and 30 cm in height) filled with field soil. They are the most closely related species in the rice genus Oryza and are collectively regarded as the wild progenitors of cultivated rice (Oryza sativa L.) (Morishima et al. rufipogon) observed for the paired populations are in parentheses. However, it is unclear how general a phenomena parallel speciation is since it was only shown in a small number of animal species. and S.G. analyzed the Pool-Seq data and conducted various simulations. However, we found that the information on variation from the summary statistics could not be recovered with subset of the PLS components, probably because of the lack of multicollinearity of our statistics. For the Pool-Seq data, we generated the Neighbor-Joining (NJ) tree, as implemented in phylip v3.69 (Felsenstein 1989), based on the neutral SNPs (see below); this method was used because the neutral loci were desirable for inferring the shared ancestry and were free of the distortion role of selection on the affinity among populations (Beaumont and Balding 2004). Phylogenetic trees were then constructed using the data sets from different combinations of the SNP grouping criteria. The survival of all organisms depends critically upon interactions with the environment, mediated largely through the action of small molecules. Wenn Sie Ihre Nobilia Einbauküche um einen zusätzlichen Schrank erweitern möchten, kann es vorkommen, dass der gewünschte Griff nur schwer zu finden ist. In addition, neither premating nor postmating reproductive barriers were observed between populations within both O. rufipogon and O. nivara (figs. Street, Thomas William Walpole, Dave R. Vaughan, Anne Marie Swanton, Thomas A. 2000; Schluter 2009; Nosil 2012; Ostevik et al. Single-headed arrows stand for colonization or migration, and double-headed arrows indicate the gene flow between populations. (a–c) Neighbor-joining trees constructed with Wright’s FST distance based on neutral (a), outlier (b), and linked (c) SNPs of whole-genome resequencing data. The single handle 218 is characterised by its clean edges and brass look. Patton Electric, 326 E High St, Waynesburg, PA 15370. In this process, many changes such as flowering time and mating system promoted assortative mating and acted as premating barriers to genetic exchanges between species (Morishima et al.

These natural populations were sampled across four localities (Nepal, Myanmar, Laos, and Cambodia) by the authors, with the distance between two populations of each pair ranging from 1.3 to 44.9 km (supplementary table S1, Supplementary Material online). We removed duplicates showing identical 5′ coordinate (Fracassetti et al. 2016). The occurrence of parallel evolution, or the repetition of evolutionary changes in similar environments strongly implicates the action of natural selection in biological diversification because random genetic drift is unlikely to generate such a pattern (Rundle et al. Significance after correction for multiple testing is in the parentheses. As a result, a total of 18 summary statistics were used. Sie sind original verpackt. Separate analyses on individual population pairs revealed that 11 traits showed significantly higher values for QST than for FST across all six pairs (ranging from 14 to all 18 traits) (supplementary fig. Genomic DNA extraction, polymerase chain reaction (PCR) amplification and sequencing of the genes followed our previous studies (Zheng and Ge 2010; Liu et al. To validate the reliability of these SNPs, an Illumina Infinium BeadChip (Illumina Inc.) was customized using the probes designed from rice whole-genome resequencing data (Huang et al. The uppermost hierarchical level of the genetic structure was estimated using the statistic ΔK following the procedure described by Evanno et al.

Goodbye Bafana (2007) Goodbye First Love Goodbye to All That Goodbye World goodfellas Goodnight, Mr. Seeds were germinated at 30°C in an incubator, and the young seedlings were then transplanted to pots at three-leaf stage and finally planted randomly in the experiment garden of GAAS. 914-218-4637 STRUCTURE analysis showed that the best supported clustering (K = 2) suggested the deepest divergence between two regions (South Asia vs. Southeast Asia) rather than between the two species (fig.

S1, S2, and S6, Supplementary Material online; see Materials and Methods). Parallel ecological speciation in plants?
