What is genetic modification (GM) of crops and how is it done?

This site attempts to track all plant genomes with published sequences, and at least some of the genomes currently in the process of being sequenced. Genomes are divided into four states:. Have we missed a published genome sequence? Get in touch and let me know! For a table of sequenced plant genomes with additional statistics and information: Plant Genome Statistics. Amborella Amborella trichopoda is believed to represent the earliest diverging lineage of flowering plants angiosperms still alive today.

While that doesn't mean it represents the ancestral state of flowering plants, comparing amborella to the major flowering plant lineages -- the eudicots, monocots, and magnoliids the last of which still doesn't have even a single published genome, someone please get on that! As the species is found only in New Caledonia and isn't exactly common even there, we are very fortunate that this sole representative species has survived to the present day.

The first draft of the Amborella trichopoda genome was released at the twentieth Plant and Animal Genome Conference in January of The genome is currently covered by Fort Lauderdale restrictions, but is available for download from the Amborella Sequencing project's website. Amborella Genome Database. Columbine Aquilegia sp. Comparing the columbine genome sequence with other eudicot genomes should be very interesting for several groups of plant biologists comparative genomicists and evolutionary biologists in particular.

The current assembly is only to the scaffold level no pseudomolecules and consists of megabases of sequence spread over scaffolds. Current gene annotations identify 25, genes identified by a mixture of EST sequencing and homology to other sequenced genomes.

You can view in CoGe with GenomeView. As with all sequenced angiosperm genomes, columbine has an ancient whole genome duplication. However, is this the paleohexaploidy event shared among the rosids and asterids? Columbine's whole genome duplication. It was domesticated in Asia about 7, years ago, and cultivated for its rhizomes and seeds as a food crop. It is particularly noted for its 1,year seed longevity and exceptional water repellency, known as the lotus effect.

The latter property is due to the nanoscopic closely packed protuberances of its self-cleaning leaf surface, which have been adapted for the manufacture of a self-cleaning industrial paint, Lotusan. The final assembly has a contig N50 of The genome notably lacks the paleo-triplication observed in other eudicots, but reveals a lineage-specific duplication.

Comparisons of the available sequenced genomes suggest a minimum gene set for vascular plants of 4, genes. Strikingly, the sacred lotus has 16 COG multi-copper oxidase family proteins with root-specific expression; these are involved in root meristem phosphate starvation, reflecting adaptation to limited nutrient availability in an aquatic environment.

The slow nucleotide substitution rate makes the sacred lotus a better resource than the current standard, grape, for reconstructing the pan-eudicot genome, and should therefore accelerate comparative analysis between eudicots and monocots. Sugar beets are a relatively recent agricultural innovation with selective breeding of beets for high sugar content only starting in and production not being adopted on a wide scale until the Napoleonic wars, during which large parts of Europe were essentially cut off from trade with the Caribbean, until then Europe's primary source of sugar from sugar cane.

Beets belong to the Caryophyllales an order of flowering plants which also includes the true cacti and many carnivorous plants. The Caryophyllales are currently believed to be more closely related to the Asterids than the Rosids, but are not included within either group.

The beet genome is currently at version 0. The genome is based upon a doubled haploid line called KWS Version 1. For more information and to download the genome, visit the sugar beet genome sequencing group's website. Published in in Nature The genome of the recently domesticated crop plant sugar beet Beta vulgaris. The asterids are a group of plants within the eudicots that include species like the solanacious vegetables Tobacco, Tomato, Potato, Peppers and Eggplant and the sunflowers.

The tomato Solanum lycopersicum genome paper was published in Nature in May The version of the genome currently loaded into CoGe is assembled into pseudomolecules [1]. The most recent assembly is 2. Read more about the tomato genome project here. Because of its extreme stress tolerance and unusual morphology, it is an important donor of germplasm for the cultivated tomato Solanum lycopersicum.

Introgression lines ILs in which large genomic regions of S. Here we describe a high-quality genome assembly of the parents of the IL population. By anchoring the S. Our work paves a path toward further tomato improvement and for deciphering the mechanisms underlying the myriad other agronomic traits that can be improved with S. It was sequenced by a group of scientists at the Cold Spring Harbor Laboratory.

It has also been used in biochemical analysis of fruit sucrose accumulation 3. Potatoes are arguably the second most important non-grass crop grown around the world. Both breeding and genomic analysis of the potato have been hampered by the fact that most cultivated potatoes are recent tetraploids.

The genome of potato was published by an international consortium with corresponding authors hailing from the United States, China, and the Netherlands in It is the first publicly available genome from within the asterid clade. To avoid the complexities introduced by tetraploidy, the genome consortium focused on a diploid potato variety and used doubled-monoploid technology to create an "instantly inbred line.

The potato lineage has experienced one additional tetraploidy since the ancient hexaploidy shared by the asterids and rosids. A total of 39, protein coding genes were annotated in the current assembly. Download link. Genome sequence and analysis of the tuber crop potato. Nature , — DOI Clustering analysis of the predicted genes of eggplant along with the genes of three other solanaceous plants as well as Arabidopsis thaliana revealed that, of the 35, clusters generated, 4, were exclusively composed of eggplant genes that would perhaps confer eggplant-specific traits.

Between eggplant and tomato, 16, pairs of genes were deduced to be orthologous, and 9, eggplant scaffolds could be mapped onto the tomato genome. Furthermore, 56 conserved synteny blocks were identified between the two species.

The detailed comparative analysis of the eggplant and tomato genomes will facilitate our understanding of the genomic architecture of solanaceous plants, which will contribute to cultivation and further utilization of these crops. One research group, composed mostly of Korean scientists published their genome assembly in Nature Genetics while a second group including many Chinese scientists published their version of the genome in PNAS a short while later. The pepper genome is large as plant species with published genomes go at 3.

The researchers who published the genome found that much of that size comes from a single bloom of long terminal repeat retrotransposon activity which occurred only , years ago. This popularity derives from its well-characterized susceptibility to diverse pathogens and, especially, its amenability to virus-induced gene silencing and transient protein expression methods. Here, we report the generation of a fold coverage draft genome sequence of N.

The estimated genome size of N. The current assembly consists of approximately , scaffolds, spanning 2. Of the approximately 16, N. The usefulness of the sequence was demonstrated by the retrieval of N. The sequence will also be useful for comparative genomics in the Solanaceae family as shown here by the discovery of microsynteny between N. The monkey flower Mimulus guttatus genome is not yet complete. Phytozome suggests citing this manuscript if you publish whole genome scale analyses of the monkey flower genome.

Fraxinus excelsior Unpublished but available under Ft. Lauderdale from a group lead by Richard Buggs in England. Data on the genome sizes and the phylogeny of Genlisea suggest that this is a derived state within the genus. Thus, G. Here we report sequencing and de novo draft assembly of G. The assembly consists of 10, contigs of the total length of Its comparison with the genome of Mimulus guttatus, another representative of higher core Lamiales clade, reveals striking differences in gene content and length of non-coding regions.

Genome contraction was a complex process, which involved gene loss and reduction of lengths of introns and intergenic regions, but not intron loss. The gene loss is more frequent for the genes that belong to multigenic families indicating that genetic redundancy is an important prerequisite for genome size reduction. The miniature genome of a carnivorous plant Genlisea aurea contains a low number of genes and short non-coding sequences.

Identifying genes involved in synthesis of bioactive compounds could enable breeding berry varieties with enhanced health benefits. Results: Toward this end, we annotated a draft blueberry genome assembly using RNA-Seq data from five stages of berry fruit development and ripening.

Genome-guided assembly of RNA-Seq read alignments combined with output from ab initio gene finders produced around 60, gene models, of which more than half were similar to proteins from other species, typically the grape Vitis vinifera.

Comparison of gene models to the PlantCyc database of metabolic pathway enzymes identified candidate genes involved in synthesis of bioactive compounds, including bixin, an apocarotenoid with potential disease-fighting properties, and defense-related cyanogenic glycosides, which are toxic.

Cyanogenic glycoside CG biosynthetic enzymes were highly expressed in green fruit, and a candidate CG detoxification enzyme was up regulated during fruit ripening. Candidate genes for ethylene, anthocyanin, and other biosynthetic pathways were also identified. RNA-Seq expression profiling showed that blueberry growth, maturation, and ripening involve dynamic gene expression changes, including coordinated up and down regulation of metabolic pathway enzymes, cell growth-related genes, and putative transcriptional regulators.

Analysis of RNA-seq alignments also identified developmentally regulated alternative splicing, promoter use, and 3' end formation. Conclusions: We report genome sequence, gene models, functional annotations, and RNA-Seq expression data which provide an important new resource enabling high throughput studies in blueberry.

In terms of taxonomy, cranberries are in the core Ericales, an order for which genome sequence data are currently lacking. In addition, cranberries produce a host of important polyphenolic secondary compounds, some of which are beneficial to human health. Whereas next-generation sequencing technology is allowing the advancement of whole-genome sequencing, one major obstacle to the successful assembly from short-read sequence data of complex diploid and higher ploidy organisms is heterozygosity.

The genome size of V. The number of predicted genes was 36, and represents Of the predicted genes, 30, were assigned to candidate genes based on homology. Shotgun sequencing of the cranberry genome, with an average sequencing coverage of 20X, allowed efficient assembly and gene calling.

The differential accumulation and elimination of repetitive DNA are key drivers of genome size variation in flowering plants, yet there have been few studies which have analysed how different types of repeats in related species contribute to genome size evolution within a phylogenetic context. This question is addressed here by conducting large-scale comparative analysis of repeats in 23 species from four genera of the monophyletic legume tribe Fabeae , representing a 7. Phylogenetic analysis and genome size reconstruction revealed that this diversity arose from genome size expansions and contractions in different lineages during the evolution of Fabeae. In turn, this enabled an analysis of how each major repeat type contributed to the genome size variation encountered. Repeat analysis within a phylogenetic framework also revealed profound differences in the extent of sequence conservation between different repeat types across Fabeae.
