Disclaimer, National Library of Medicine The quality of the assembled genome was ascertained by performing several independent tests, as described in Supplementary Note 3. MAKER: an easy-to-use annotation pipeline designed for emerging model organism genomes. Animals require linolenic acid as a precursor for many biomolecules for their proper development and the maintenance of health and survival. The structure of the genomes of C. sativa and C. microcarpa appear to be identical indicating a common origin supporting the suggestion that C. microcarpa is the wild pre-domesticated hexaploid ancestor of C. sativa [36]. It is native to Central Asian areas. More than 80% of the 736 non-redundant genes31 governing various steps in acyl-lipid biosynthesis, accumulation and degradation were found to be retained in three copies (Supplementary Table 21). Branch lengths represent estimated nucleotide substitutions per site. 1). This study indicates that an altered fatty acid composition in plants can have an impact on the associated food web, showing the necessity for an adequate assessment of these plants. Ectopic expression of cDNAs from larkspur (Consolida ajacis) for increased synthesis of gondoic acid (cis-11 eicosenoic acid) and its positional redistribution in seed triacylglycerol of Camelina sativa. Journal of the American Oil Chemists' Society. The majority of the triplicated genes (78%) showed no significant differences in either expression levels or tissue specificity, which could impact manipulation of the crop phenotype. USA 108, 40694074 (2011). In other, classic transgenic approaches camelina seeds were genetically modified to produce the long-chain PUFAs eicosapentaenoic acid(EPA) and docosahexaenoic acid(DHA), that naturally occur in marine fish only and cannot be found in terrestrial animals [105, 106]. Front Plant Sci 8:1789. https://doi.org/10.3389/fpls.2017.01789, Browse J, Somerville C (1991) Glycerolipid synthesis: biochemistry and regulation. In many plant taxa, polyploidization and proliferation of transposable elements (TEs) are recognized as prevalent factors in plant genome expansion6,7. Colombo et al. Genome editing is supposed to induce changes in complex genomes of, for example, camelina, wheat or sugarcane [31, 34, 38] generating novel genotypes in plants. However, the evolutionary origin and mode of the polyploidization event that formed the C. sativa genome as well as the post-polyploidization evolutionary path leading to its diploidization are currently not understood. Gehringer A, Friedt W, Luhs W, Snowdon RJ. 2022 Mar 14;11(6):772. doi: 10.3390/plants11060772. When expressed in Camelina sativa seeds the recombinant proteins of specific chimeras elevated total lipid content of the seeds as well as increased seed size. We thank Doug Heath at Genome Prairie for project management support and Cathy Coutu for providing pod tissue for RNA extraction. Close. Depending on the target sequence and the designed gRNA, it is possible that homoeologous genes in only one or two of the sub-genomes of camelina are edited. The impact of artificial EPA and DHA added in the diets of a terrestrial crop pest of Brassicaceae plants, larvae of the cabbage white butterfly Pieris rapae, was tested [107]. In another publication, all gene copies encoding FAE1 were targeted causing an increase of oleic acid content from 13% up to 20% and a reduction of very-long-chain fatty acids from 12 to 1% [39]. The genomes of Cs-G1 and Cs-G2 are more closely related to each other than any of the diploids assayed, which could suggest an initial tetraploidisation event of two closely related species (that is, possibly an amphidiploid), subsequently followed by an additional hybridization event through which Cs-G3 joined, resulting in a hexaploid genome. Accessibility Using the assembled C. sativa genome as input, a de novo repeat library was constructed by using RECON and RepeatScout within RepeatModeler (Version 1.05; http://www.repeatmasker.org/RepeatModeler.html).

The Prairie Gold Project was established to generate genetic and genomics resources for this new crop, including the development of a genome sequence. C. sativa is an annual plant in the Brassicaceae family and cultivated mostly in Europe and in North America. Glob Change Biol Bioenergy 6(3):242251. Camelina sativa is a flowering plant in the family Brassicaceae and is usually known in English as camelina, gold-of-pleasure, or false flax, also occasionally wild flax, linseed dodder, German sesame, and Siberian oilseed. Tang, H. et al. 2018 Oct;127:834-842. doi: 10.1016/j.ympev.2018.06.031. Nguyen HT, Silva JE, Podicheti R, Macrander J, Yang W, Nazarenus TJ, Nam JW, Jaworski JG, Lu C, Scheffler BE, Mockaitis K, Cahoon EB. One of the sub-genomes contains six chromosomes, while the other two contain seven chromosomes each [49]. PUFAs are an important component of cellular membranes regulating their fluidity, in particular for adaptation to changing climate conditions. This approach produced 201,365 transcripts, which were used in the annotation of protein-coding genes in the C. sativa genome (Supplementary Fig. PLoS ONE 3, e3376 (2008). Rev. Bennetzen, J. L. Mechanisms and rates of genome expansion and contraction in flowering plants. 5). A ~10-fold coverage BAC library of C. sativa was constructed in the pIndiogoBAC vector by Bio S&T Inc. (Montreal, Canada). doi: 10.1093/molbev/msac074. Epub 2019 Sep 27. Here, the special focus is the potential of SDN-1 techniques to generate novel genotypes and the impact of intended changes in genome-edited plants in relation to the interactions in their respective environments. SDN-1 applications have potential to penetrate the whole genome and cause profound alterations in the biological characteristics of plants without introducing any additional DNA sequences. Thus, it contains multiple alleles of homologous genes. Genetica 115, 2936 (2002). (b) Reconstruction of the three sub-genomes of C. sativa. Careers. However, a number of additional unique GB associations observed in C. sativa, such as D/I, E/I, N/J, Q/V, O/W and O/R have not been reported in ancestral Brassicaceae karyotypes defined so far. Provided by the Springer Nature SharedIt content-sharing initiative. The predicted number of protein-coding genes in C. sativa is significantly higher than other currently sequenced plant genomes (Fig. The highly undifferentiated polyploid genome of C. sativa presents significant consequences for breeding and genetic manipulation of this industrial oil crop. The adoption of genetic engineering significantly contributed to crop improvement, such as increased seed and oil yield and enhanced drought resistance in camelina. https://doi.org/10.1111/pbi.13193, Kannan B, Jung JH, Moxley GW, Lee SM, Altpeter F (2018) TALEN-mediated targeted mutagenesis of more than 100 COMT copies/alleles in highly polyploid sugarcane improves saccharification efficiency without compromising biomass yield. Download BLAST Camelina sativa Genome Project Camelina sativa, an oilseed crop popular in Europe prior to the dominance of rapeseed and canola, is increasingly recognized as a valuable industrial oil platform. 19).

A detailed protocol is described in Supplementary Note 6. Bees on a low omega-3 diet had reduced levels of PUFAs in their body, a slightly reduced brain and a reduced hypopharyngeal gland. 42, 443461 (2008). Thus, there is need for debate on potential ecological risks when genome-edited organisms are released into the environment, also considering the speed of newly developed genome-edited plants and especially combinatorial and accumulating effects upon the release of many different genome-edited organisms.

Additionally, Csa16, Csa7 and Csa5/9 from Cs-G1, Cs-G2 and Cs-G3, respectively, carrying these two novel GB associations display further rearrangements resulting in a common organization of GBs as J/I/D/E/I/E/I/D (Fig. 4), 89,418 non-redundant C. sativa genes were predicted, of which 4,753 (5.3%) genes encoded two or more alternatively spliced isoforms (Supplementary Table 4). Jpn J. Bot 7, 389452 (1935). Inputs for Maker included the repeat-masked C. sativa genome assembly, 42,350 ESTs, a genome-guided de novo transcript assembly comprising 201,365 transcripts and a protein database containing annotated proteins from A. thaliana, A. lyrata, B. rapa and Thellungiella parvula. Camelina sativa (false flax, gold of pleasure, German sesame) is a relict oilseed crop of the Crucifer family (Brassicaceae) with centres of origin in SE Europe and SW Asia. Genome-edited C. sativa was used here as an example to illustrate how far biotechnology has come to generate novel, genetic combinations in an agriculturally relevant crop, and the likely and potential ecological impacts. Mol Plant 8(8):12741284. Plant Cell. For nuclei isolation, ~40g of fresh leaf tissue from 4-week-old etiolated DH55 seedlings was homogenized in 200ml ice-cold homogenization buffer (0.01M Trizma base, 0.08M KCL, 0.01M EDTA, 1mM spermidine, 1mM spermine, 0.5M sucrose plus 0.15% -mercaptoethanol, pH 9.49.5). Phosphorus is known as a key element associated with growth, energy, and cell signaling. In false flax (Camelina sativa), an important hexaploid oilseed crop closely related to Arabidopsis (Arabidopsis thaliana), the putative parental species as well as the origin of other Camelina species remained unknown.

The omega-3 dietary deficiency also greatly reduced the bees performance in both olfactory and tactile associative learning assays [104]. 12) was drawn using the statistical package R where the colours were 256 levels of rainbow, starting with red representing low values and ending with blue representing high values. Bethesda, MD 20894, Web Policies Genome Viewer Gene Expression Sequences The following sequences are available for this feature: . The intended trait and potentialunintentional changes to secondary metabolism are considered in the context of potential ecological consequences following a release to the environment. Cutinized and suberized barriers control, among others, water and ion transport in these tissues enabling the plants to withstand abiotic stresses, such as drought and salinity, and also biotic stresses acting as anti-microbial barriers [89, 90]. (2010) suggested that C. sativa is allohexaploid with three single-copy nuclear genes present as three paralogous copies in the genome [48]. In case genome-edited plants (e.g. Gout, J.-F., Kahn, D. & Duret, L. Paramecium Post-Genomics Consortium. Nat. A homozygous doubled haploid line and derived from C. sativa genotype SRS 933. Google Scholar, Iskandarov U, Kim HJ, Cahoon EB (2014) Camelina: An emerging oilseed platform for advanced biofuels and bio-based materials. This novel genetic variability can cause unwanted effects in the plants during their development or under stress conditions, and potentially disturb signalling pathways and ultimately plant-environmental interactions in case of a release. Ind Crops Prod 94:690710. Also, the whole-genome sequence for other crop species from the Brassicaceae family, e.g. To estimate transcript abundance, the whole-plant and tissue-wise expression of C. sativa genes was assessed using a Tophat and Cufflink-based method47. There are multiple examples demonstrating that an altered fatty acid content of plants can have an impact on the associated food web (e.g., insects that consume them). 14, 149159 (2004). Repeat annotation revealed that 28% (180.12Mb) of the assembled C. sativa genome comprises TEs (Supplementary Table 9).
