“…Se is an essential micronutrient for organisms and has beneficial effects on animal and human health [ 4 ], although toxicity can occur with acute or chronic ingestion of excess Se [ 5 ]. Se is taken up from the soil by plants in two forms: inorganic (selenate and selenite) and organic (selenomethionine and selenocysteine) [ 6 ]. Both inorganic and organic forms can be good dietary sources of selenium for humans [ 6 ].…”

Lentil (Lens culinaris Medik.) is an excellent source of protein and carbohydrates and is also rich in essential trace elements for the human diet. Selenium (Se) is an essential micronutrient for human health and nutrition, providing protection against several diseases and regulating important biological systems. Dietary intake of 55 μg of Se per day is recommended for adults, with inadequate Se intake causing significant health problems. The objective of this study was to identify and map quantitative trait loci (QTL) of genes controlling Se accumulation in lentil seeds using a population of 96 recombinant inbred lines (RILs) developed from the cross “PI 320937” × “Eston” grown in three different environments for two years (2012 and 2013). Se concentration in seed varied between 119 and 883 μg/kg. A linkage map consisting of 1,784 markers (4 SSRs, and 1,780 SNPs) was developed. The map spanned a total length of 4,060.6 cM, consisting of 7 linkage groups (LGs) with an average distance of 2.3 cM between adjacent markers. Four QTL regions and 36 putative QTL markers, with LOD scores ranging from 3.00 to 4.97, distributed across two linkage groups (LG2 and LG5) were associated with seed Se concentration, explaining 6.3–16.9% of the phenotypic variation.

“…An intermediate metabolite selenocystathionine (KEGG C05699) was detected, which is involved in selenocompound metabolism and formed as a by-product of cystathionine synthesis by the enzyme cystathionine beta-synthase (Çakır, Turgut-Kara, & Arı, 2012;Haug, Graham, Christophersen, & Lyons, 2007). Selenocystathionine is consumed as a functional food supplement, because it is involved in the hyper-accumulation of selenium, which is an anti-cancer agent (Çakır et al, 2012).…”

“…In addition, crude ethanol and ethyl acetate extracts of the roots have shown cytotoxic activity, apoptosis-inducing effects (Karagö z et al 2007;Arican et al 2012) and antioxidant effects, which enhanced the phagocytic activity of lymphocytes (Hasancebi S., unpublished data). In addition, this plant was shown to take up selenium as a secondary accumulator (Ari et al 2010), and a selenocysteine methyltransferase gene of this plant was isolated and characterized (Cakir et al 2012). Successful application of plant biotechnology for plant improvement requires the development of efficient and healthy in vitro regeneration systems.…”

Kahraman (2015) Effects of long-term culture of Astragalus chrysochlorus callus onmorphology, genetic structure, gene expression and metabolism, AbstractThe objective of this study was to investigate the phenotypic and genetic effects of long-term (12 years) in vitro culturing of Astragalus chrysochlorus callus tissue. Murashige and Skoog medium supplemented with 0.5 mg/l 2,4-dichlorophenoxyacetic acid was used for the production of young callus (2 months old) from hypocotyl explants. Morphological analysis showed that long-term cultures were well adapted, with greener and more friable calli, and a higher growth index (2.11^0.39) was compared with that in short-term cultures (1.2^0.73). Genetic variation between the two types of calli was investigated by randomly amplified polymorphic DNA analysis, which showed different amplification patterns with a polymorphism level of about 45%. We furthermore measured RNA transcript levels for two key enzymes of the important stress-related phenylpropanoid pathway, PAL and C4H, via quantitative polymerase chain reaction. The gene expression levels of C4H and PAL were 0.205-and 0.584-fold lower in old cultures than in young cultures. Metabolic analysis by high performance thin layer chromatography clearly showed differences in flavonoid type metabolic content. Together, these data show that long-term culturing of callus tissue leads to genetic heterogeneity and variations in secondary metabolite content.
