Guar (Cyamopsis tetragonoloba [L.] Taub.) is an important legume crop native to India and Pakistan. Seeds of this plant serve as a rich source of guar gum (galactomannan polysaccharide) used in the food industry as a stabilizer (E412), as well as a gelling agent in liquids for hydraulic fracturing for the oil and gas industry. Our team has attempted to create the first draft of the guar genome using a combination of Illumina short-read and MinION long-read sequencing technologies, achieving approximately 347X coverage of the total guar genome.


Elizaveta Grigoreva is a bioinformatician currently working in the plants and forest field in Saint-Petersburg State Forestry University and Sirius University of Science and Technology. One of her main projects is de novo genome assembly of the guar genome (Cyamopsis tetragonoloba [L.] Taub.) using a hybrid approach and metabolome-transcriptome integrative analysis.
