It is a unique desert plant with extreme longevity and two ever-elongating leaves. We present classifiation chromosome-level assembly of its genome my iphone wont connect to wireless network. We also present a refined, high-quality assembly of Gnetum montanum to enhance what is mathematics simple definition understanding of gnetophyte genome evolution.

High levels of cytosine methylation particularly at CHH motifs are associated with retrotransposons, whilst long-term deamination has resulted in an exceptionally GC-poor genome. This can last several thousand years, resulting in the longest-lived leaves in the plant kingdom 234. Ever since its first formal description in 5the biological curiosities of Welwitschia have been the leve,s of extensive discussion, including between Charles Darwin, Asa Gray, and Hooker 6.

The distribution of W. Jürgens pers. Welwitschia is the only species of the plant family Welwitschiaceae although recent molecular data suggest there are two genetically and geographically distinct populations that may correspond to sub-species 1. The species is within Gnetophyta, an ancient gymnosperm lineage that includes only two other genera, Gnetum family Gnetaceae and Ephedra family Ephedraceae.

Most phylogenetic analyses reveal that gnetophytes are monophyletic, with Welwitschia and Gnetum forming a clade that is sister to Ephedra 7. The divergence of Welwitschia and Gnetum is likely to have been over million years ago myagiven a welwitschioid fossil seedling, Cratonia cotyledonfound in early Cretaceous beds of Brazil niology. The relationship of gnetophytes to other gymnosperms and angiosperms has caused much speculation due to their conflicting phylogenetic placement 910unique morphological features biplogyand the extinction of critical seed plant groups Here, we report a high-quality chromosome-level sequence assembly of Welwitschia Supplementary Table 1.

Contig and scaffold N50 lengths were 1. Optical and chromosome-contact HiC maps for both Welwitschia and Gnetum were then produced and scaffolds were te and ordered to generate 21 and 22 pseudo-chromosomes for Welwitschiaand Gnetumrespectively Supplementary Fig. The pseudo-chromosomes represent These results agree with previous cytogenetic observations showing the karyotype of Welwitschia to comprise telocentric chromosomes differing considerably in total length A total te 26, protein-coding genes were predicted of which For Gnetumthe improved assembly shows a considerable enhancement over the previous release, with scaffold N50 lengths of The distribution of synonymous substitutions per synonymous site K S for all paralogous genes in the genomes of Welwitschia and Gnetumas well as for paralogous genes in collinear or syntenic regions, suggests an ancient whole-genome duplication WGD event for Welwitschiabut not Gnetum Fig.

In Welwitschiathere is a signature peak of duplicate genes with a K S value close to 1 Fig. The Gnetum genome is also devoid of intra-genomic collinear regions, while ard Welwitschia we detected pairs of paralogous genes in 47 such duplicated regions in the genome Supplementary Fig. Inter-genomic comparisons between both gnetophyte genomes further identified 21 genomic segments in the Gnetum genome, each corresponding to two sre segments in the Welwitschia genome Fig. The bands denote collinear regions where one region in Gnetum corresponds to two orthologous regions in Welwitschia.

Genes in light gray are non-homologs. Genes with the same leves are homologs and homologous genes are connected with dark gray bands when the two segments are alongside. The y axis on the left shows the number of retained duplicates and there is a small peak clasisfication K S of 1, which represents a WGD event. The y axis on the right shows the orthologue density between the two species.

For one-to-one orthologs between Welwitschia — Gnetum and Welwitschia — Ginkgo color-filled curves of kernel-density estimates the peaks represent species divergence events and K S values correspond with the degree of orthologue divergence. The K S values for anchor pairs from classifucation regions are indicated in orange left y axis.

The pale gray rectangle highlights the K S regions in which the paralogous genes were used for absolute dating. There were many more complete elements identified in Ginkgo 4, than in the other species, elements that were likely to have been derived from a peak of activity about 15 mya. Source data underlying Fig. Interestingly, although Welwitschia and Classificatioj have a similar number of chromosomes; 21 and 22, respectively, collinear regions from a single chromosome in Tje often found their orthologs distributed on several chromosomes in Welwitschia Fig.

In what is no correlation in statistics of this, when considering synteny by which paralogous genes are retained but gene collinearity has been lost wyatwe found an additional paralogous genes located in syntenic regions, giving further strong support to the WGD in Welwitschia Supplementary Fig. The majority In addition, there is no indication of subtelomeric tandem repeats in Welwitschiaalthough they do occur in Gnetum Supplementary Fig.

Recent bursts of non-autonomous elements have been observed in high-quality genome assemblies of two angiosperm species Camellia sinensis 18 what are the levels of classification in biology Oryza species 19 and may be a phenomenon that becomes more commonly observed as genome assembly qualities improve. Biklogy, retrotransposition of non-autonomous elements inhibits the retrotransposition frequency of complete elements, through competition wnat the proteins needed for amplification that are encoded by autonomous elements 1819hence explaining the high frequency of non-autonomous elements in Welwitschia.

Phylogenetic analysis of reverse transcriptase RT genes from complete retrotransposons Ty3- gypsy and Ty1- copia elements, containing all expected protein-coding domains what are the levels of classification in biology WelwitschiaGnetumAmborella what are the levels of classification in biology hereafter, Amborellaand Ginkgo biloba hereafter, Ginkgo revealed deep, ancient diverging clades containing sequences from WelwitschiaGnetum, and sometimes also Amborellabut excluding sequences from Ginkgo Fig.

Our previous work comparing full-length Ty3- gypsy and Ty1- copia elements yhe Gnetum with Pinus taeda 13were similar to the comparisons between Gnetum and Ginkgoin that most LTR clades were species-specific and had deep divergent histories, indicating the slow accumulation of ancient repeats independently in each lineage. These results contrast with the repeats from WelwitschiaGnetum and Amborellawhere multiple deeply diverging clades were not species-specific, oof retained elements from all three species.

Our analyses failed to uncover evidence of numerous Welwitschia -specific clades except perhaps some Ty3- gypsy clades, Fig. There were also many more complete autonomous elements identified in Ginkgo than in the gnetophytes or Amborella Supplementary Table 6. Solo-LTRs are thought to arise through excision-based DNA recombination, including between adjacent LTRs of the same element, leading to their removal and genome downsizing Perhaps, what are the levels of classification in biology higher frequency of solo-LTRs in Welwitschia compared with Gnetum reflects an elevated lecels of recombination-based removal of retroelements.

Overall, in the last two million years it appears that the Welwitschia genome has been impacted by the expansion of both autonomous and non-autonomous LTR repeats within a background of the ongoing reduction in all classsification of retroelements. We compared the DNA methylome of two types of somatic tissue basal meristem and young leaves in Welwitschia Classificxtion Tables 7 yhe 9Supplementary Note 2studying both greenhouse material and material collected in the wild see Plant Materials.

The global what is equity market risk premium levels of leveps in CG dinucleotide and CHG H represents A, T, or C trinucleotide sequence contexts were high in meristems and leaves, reaching on average The average methylation level of cytosines in the CHH context in both meristem and leaf tissue was Heat maps showing CG, CHG, and CHH methylation in the basal meristem of claseification male individual sampled in the wild MM1a young leaf from a male individual the newly emergent region, MY1and a male individual from the greenhouse, including the central region of the basal meristem CMthe peripheral part of the basal meristem PM and leaf L.

Despite the high average level of CHH methylation in Welwitschiavalues varied considerably between tissues and contributed substantially to the occurrence of genome-wide differentially methylated regions DMRs Fig. Furthermore, most genes directly involved in the deposition of methyl groups onto cytosine were upregulated in basal meristems clsssification. Because of the upregulation relational database definition in english genes involved biolofy both canonical and non-canonical RdDM pathways, we assessed what are the levels of classification in biology levels of uniquely mapped reads of 21, 22, 23, and 24 nt smRNAs Supplementary Table The hypermethylation of TEs in meristematic tissue is likely to have been reinforced by both canonical and non-canonical RdDM pathways due to the abundance and nature of 21 and 24 what are the levels of classification in biology siRNA.

Differential methylation of these elements reflects both developmental oof i. The latter may reflect responses to environmental stresses light, temperature, water experienced by the wild-collected plants growing in the Namibian desert. Beyond that, the reinforcement of TE silencing is crucial for the maintenance of genome integrity in stem cells and undifferentiated cells since these can develop into tissues such as reproductive organs. High levels of epigenetic silencing of TEs may also be an important, albeit costly response in terms of nutrients and energy requirements of the epigenetic machinery of repeat silencing to maintain meristem integrity in long-lived organisms.

Such low levels were also observed in regions identified as being collinear with Gnetumwhich are not so GC poor, suggesting that the nucleotide landscapes have arr considerably since the genera diverged Supplementary Fig. We found that TEs, including what are the levels of classification in biology protein-coding domains, had remarkably high levels of methylation, although their GC content was low The higher GC content in genes compared with other genomic domains could be tthe consequence of GC-biased gene conversion, which is reported to occur in recombination-rich regions of the genome Together, these results indicate that long-term deamination tye methylated cytosines has occurred particularly in the intergenic regions of Welwitschiareflected by the reduced GC content of What are the levels of classification in biology and incomplete LTR-RTs.

Genomic DNA with high GC content is considered to be more thermostable 34yet incurs a higher biochemical cost compared with AT base synthesis What is the book thief mainly about has been shown that nutrient limitation provides a strong selection explain how gene therapy works on nucleotide usage in prokaryotes 36 classificahion plants 37 leading to a bias towards AT-rich teh.

Thus, it is possible that the long-term deamination of methylated cytosine residues, and a reduction in genome size after wht ancestral WGD event, would have resulted in a more streamlined, water and nutrient-efficient genome especially given the nutrient costs needed for high levels of methylation silencing, above that is better adapted to harsh, nutrient- and water-limited conditions. Unlike other plants, the shoot apical meristem of Welwitschia dies in the young plant shortly after the appearance of true leaves and meristematic activity moves to the basal meristem.

This meristem generates the two long-lived, highly fibrous, and strap-like leaves, which show indeterminate growth and emerge from two terminal grooves at the top of the stem like a conveyor belt 3383940 Fig. The number of genes associated with each category is indicated in brackets after the term description, classificatikn enrichment values are indicated by color, as shown in the color what are the levels of classification in biology.

The probability ot the node what are the levels of classification in biology gene s that are controlling differential gene expression between tissues is depicted by node color. The lines connecting each node indicate correlated gene expression between genes. Hypomethylated cytosines at CHH trinucleotides biokogy the promoter region of NCED4 negative values in particular correlate with increased expression in young leaf sections MY compared with basal meristem tissues MM.

To search for further signatures of indeterminate leaf growth, we characterized gene activity in the basal meristem compared with leaves using GO what is meant by classification of data class 11 and weighted gene co-expression network analyses WGCNA Fig.

Brassinosteroids play an important role in driving what are the levels of classification in biology growth and cell proliferation 4344 We, therefore, investigated whether classificatino upregulation of these genes was also associated with increased synthesis of brassinosteroids and observed, as expected, higher levels of castasterone in basal meristems compared with leaves Supplementary Fig. All these data are consistent with the ongoing meristematic activity required for the llevels, indeterminate growth of Welwitschia leaves in the environmentally stressful conditions experienced by the plants throughout their long lives.

To find genes that may have expanded in copy number in response to the unusual growth habit or to stress, we conducted a comprehensive characterization of expanded gene families in Welwitschia compared to other representative land plants Supplementary Fig. From these, we identified and further characterized genes in Welwitschia that had particularly increased in copy number and are known to be involved in stress responses.

We observed that both meristematic tissue and young leaf tissue had higher expression levels of these proliferated genes than old leaf sections Supplementary Fig. In Arabidopsisoverexpression of AtMYB11 is associated with reduced growth rate and reduced proliferation activity in meristem cells The expansion of R2R3-MYB genes might therefore be an adaptive response in Welwitschia for regulating cell division in the basal rae to enable the slow and continuous growth, elvels development, and maturation over the long periods when environmental conditions are unfavorable.

The upregulation of lignin biosynthesis pathway genes is associated with woody fibers laid down in early leaf development Supplementary Data 4. In addition, subfamilies of the SAUR genes small auxin upregulated RNA genes involved in regulating cell elongation in plants 54 were uniquely bioloty in copy number in Welwitschia Supplementary Note 6.

Typically, SAUR genes occur in plant genomes in 60— copies 54 whereas in Welwitschia there are specific expansions whxt gene members in two subfamilies SAUR17 and SAUR43,58 compared classivication six angiosperms, three gymnosperms, and one bryophyte species analyzed Supplementary Wbat. All of these genes are involved in the elongation and development of the highly fibrous strap-like leaves, acting to protect them from herbivory and shearing damage by wind and sandstorms.

Caseinolytic protease ClpP in plants has a role in maintaining functional proteins through the removal of misfolded, damaged, and whaat proteins in plastids 55 In Arabidopsis thaliana and Oryza sativa claesification, Clp proteases are more abundant in younger leaves than older ones 5758whereas some paralogues, like Clp 3 and Clp 5show higher expression in senescing Arabidopsis leaves 59perhaps associated with stress responses in these dying tissues.

These proteins are likely to be important in the transition of proplastids to photosynthetically active chloroplasts in the young leaf, which is one of the most hiology metabolic processes in plant growth 58 The expression of these proteins from the earliest emergence of the leaf to sections of the leaf 6 years later is likely to reflect the necessity to maintain protein homeostasis throughout the long life of the leaf, in the face of significant temperature and water stress. Further studies to investigate how Welwitschia is able to survive classufication such hostile environments involved exploring the heat shock proteins HSPswhich are known to protect other proteins from whar misfolding, denaturation, and aggregation under both temperature and salt stress We also observed that they were upregulated in the basal meristem compared with leaf sections Supplementary Fig.

In wild populations, the main body of the plant can remain healthy even when the leaves are largely destroyed.
