History and prospects of flax genetic markers.

Flax ( L.) is known as a dual-purpose crop, producing both fiber and oil, which have a wide range of uses. Successful flax breeding requires knowledge on the genetic determinants of flax traits.

Identification and Analysis of , , , and Gene Families in .

(β-ketoacyl-acyl carrier protein (ACP) synthases II), (fatty acid thioesterases), (stearoyl-ACP desaturase), and (fatty acid desaturases) are the vital gene families involved in fatty acid (FA) synthesis in L. However, information on the number and location of these genes and which ones are key to the formation of FAs in fruit seeds and pulp was not complete. Our study aimed to solve this issue using the available genomic sequences and transcriptome data that we obtained.

Nanopore Data-Driven Chromosome-Level Assembly of Flax Genome.

Flax is an important crop grown for seed and fiber. Flax chromosome number is 2n = 30, and its genome size is about 450-480 Mb. To date, the genomes of several flax varieties have been sequenced and assembled.

is a pathogenic fungus that infects flax and causes significant yield losses. In this study, we assembled the genomes of four highly virulent strains using the Oxford Nanopore Technologies (ONT, R10.4.

Expression of and Genes in Developing Seeds of Flax Varieties under Different Growth Conditions.

Flax seed is one of the richest plant sources of linolenic acid (LIN) and also contains unsaturated linoleic acid (LIO) and oleic acid (OLE). Stearoyl-ACP desaturases (SADs) and fatty acid desaturases (FADs) play key roles in the synthesis of flax fatty acids (FAs). However, there is no holistic view of which genes from the and families and at which developmental stages have the highest expression levels in flax seeds, as well as the influence of genotype and growth conditions on the expression profiles of these genes.

Comparative Genomic Analysis of Strains with Different Virulence on Flax.

Key , , and Genes Involved in the Fatty Acid Synthesis in Flax Identified Based on Genomic and Transcriptomic Data.

(fatty acid desaturase) and (stearoyl-ACP desaturase) genes play key roles in the synthesis of fatty acids (FA) and determination of oil composition in flax ( L.). We searched for and genes in the most widely used flax genome of the variety CDC Bethune and three available long-read assembled flax genomes-YY5, 3896, and Atlant.

Flax ( L.) is attacked by numerous devastating fungal pathogens, including , , and (). The effective control of flax diseases follows the paradigm of extensive molecular research on pathogenicity.

Development and Complex Application of Methods for the Identification of Mutations in the and Genes Resulting in the Reduced Content of Linolenic Acid in Flax Oil.

Flax is grown worldwide for seed and fiber production. Linseed varieties differ in their oil composition and are used in pharmaceutical, food, feed, and industrial production. The field of application primarily depends on the content of linolenic (LIN) and linoleic (LIO) fatty acids.

Isolating L. Nuclear DNA Enabled Assembling High-Quality Genome.

High-quality genome sequences help to elucidate the genetic basis of numerous biological processes and track species evolution. For flax ( L.)-a multifunctional crop, high-quality assemblies from Oxford Nanopore Technologies (ONT) data were unavailable, largely due to the difficulty of isolating pure high-molecular-weight DNA.
