“…Flaxseed contains 37–42% oil, classified as a dry oil due to high alpha-linolenic acid (ALA) content. In recent years with genetic modifications through mutation breeding, modified genotypes contain less than 5% linolenic acid in the oil suitable for edible purposes 2 , 3 . Flaxseed was found to be very beneficial for human health because of its omega-3 fatty acids (alpha-linolenic acid), lignans, and fiber 4 .…”

This study aimed to investigate the effect of yellow and brown seed coat color of flax on lignan content, seed yield, and yield components under two contrasting environments of non-stress and water stress conditions. The water stress environment intensified the discrimination between the two seed color groups as the yellow seeded families had lower values for seed yield components under the water stress. Heritability and the genetic advance for seed yield were significantly higher in brown-seeded families than those of yellow-seeded ones at water stress conditions. Secoisolariciresinol diglucoside (SDG) as the chief lignan in flaxseed was more abundant in yellow-seeded families under the non-stress environment but under water stress conditions, it increased in brown seeded families and exceeded from yellow ones. Considering that the brown and yellow seed color families were full sibs and shared a similar genetic background but differed in seed color, it is concluded that a considerable interaction exists between the flax seed color and moisture stress concerning its effect on seed yield and yield components and also the seed SDG content. Brown-seeded genotypes are probably preferred for cultivation under water stress conditions for better exploitation of flax agronomic and nutritional potentials.

The flax seed is rich with lignans and α-linolenic acid plus antioxidant effects. The purpose of this study was to estimate the effect of flax seed on recovery of acute renal failure in rats. Twenty four rats were divided into four groups (each group has six individuals). One group was used as negative control (n=6), whereas the other three groups (n=18) injected with glycerol to induce acute renal failure. One of three groups fed on basal diet as positive control (C+), while the second and third groups (FS1 and FS2) was fed on 5 and 7% flax seeds for 28 days. In acute renal failure by glycerol in rats, kidneys, liver and heart weight was significantly increased when compared with negative control. RAPD amplifies the target genomic DNA with five primers generated a total of 116, 142 DNA fragments in liver and spleen, respectively. In liver, fifteen band of thirty eight (39.47 %) were polymorphic, whereas twenty three bands were monomorphic for all treatments. The highest level of polymorphism (55.56 %) was observed in primer 5 and the lowest level of polymorphism was 16.7% in primer 1. In spleen, total of bands resulted from five random primer was forty two bands, the polymorphic bands were sixteen (38.1 %) and the monomorphic band were twenty six bands (61.9 %).

Little is known about the evolutionary relationships among Linum species, basically because of the lack of transferable molecular markers. Currently, expressed sequence tags available in public databases provide an opportunity for the rapid and inexpensive development of simple sequence repeat (SSR) markers in wild flax species. In this regard, fifty expressed sequence tag-derived microsatellite markers (EST-SSRs) were evaluated for polymorphism and transferability in 50 Linum usitatissimum cultivars/accessions and 11 Linum species. Among them 23 EST-SSRs were polymorphic in L. usitatissimum, while 2-4 alleles were detected (average 2.26 per locus). The polymorphism information content value ranged from 0.08 to 0.55 (average 0.38). Forty one genic markers (95.3%) produced strong amplicons in at least two of the 11 Linum species. The percentage of cross amplification ranged from 34.1% to 92.7% in L. tauricum and L. bienne, respectively. Moreover, the rate of transferability was associated positively with the botanical section. Our results suggest that the high degree of EST-SSRs transferability to Linum species can be a useful enhancement of the current database of SSR markers for future genetic and evolutionary studies.
