Variation of Lignan Content for Sesame Seed Across Origin and Growing Environments

Abstract

Sesame lignan, including sesamin and sesamolin has been reported to have various content according to accessions and environmental factors. The objective of this study were to analyze the lignan variation of 143 sesame accessions from core collection in Korea and to test the effects of growing years and locations on lignan and lipid content of Korea sesame elite lines. The results showed that the core sesame germplasm in Korea has broad variation of lignan content from 2.33 to 12.17 mg/g with an average 8.18 mg/g. Among tested sesame accessions, the IT184615 had the highest lignan content of as 12.17 mg/g. So this accession will be a good genetic resource for developing a high lignan sesame variety. The sesamin and sesamolin content for sesame accessions across origin had significant difference. The average lignan content of accessions collected from Russia (10.0 mg/g) and Nepal (9.08 mg/g) were relatively higher than other countries. The sesamin and sesamolin content for sesame accessions across seed coat color had significant difference. The average lignan content of sesame with white, brown and black seed coat color was 8.61, 7.51, and 5.49 mg/g, respectively. The variation of lignan and lipid content was significantly different across elite lines, locations and growing years. Therefore, it is important to find sesame accessions having high lignan content with environmental stability.

Fine Mapping of a Major Pleiotropic QTL Associated with Sesamin and Sesamolin Variation in Sesame (Sesamum indicum L.)

“…The CV of sesamin in Wuchang and Yangluo was 65.12% and 58.03%, respectively, and that of sesamolin was 34.85% and 35.53%, respectively. These results are consistent with previous reports supporting that sesamin and sesamolin contents in seeds are influenced by environmental conditions [ 18 , 19 ].…”

“…Sesamin and sesamolin contents in sesame seed are quantitative polygenic traits controlled by additive and dominance effects [ 13 , 14 , 15 ]. The sesamin and sesamolin contents vary broadly in sesame germplasms [ 16 , 17 , 18 ]. Their contents are influenced by other seed components, including oil, protein, and lignin.…”

“…The same correlations have also been found in an RIL population between seed oil, protein, and sesamin contents by Wu et al [ 23 ]. In addition to seed components, differences in the content of seed lignans can also be correlated with the seed color and growing conditions [ 16 , 18 , 24 ].…”

The Effect of Water Stress on Bioactive Compounds in Australian-Grown Black Sesame

“…The fatty acid profiles of the eleven black sesame varieties are categorized based on carbon saturation levels into saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA). The composition of these fatty acids in sesame seeds varies with the seed variety and environmental factors such as soil type, weather, and growing conditions [3,60,87,88]. The SFAs, such as palmitic acid (C16:0), margaric acid (C17:0), stearic acid (C18:0), arachidic acid (C20:0), and behenic acid (C22:0), were present in all the black sesame varieties.…”

Multivariate analysis to discriminate the origin of sesame seeds by multi-element analysis inductively coupled plasma-mass spectrometry

“…Several studies have reported that the contents of the main components in sesame seeds are different depending on the origin of production, cultivating environment, and varieties (2)(3)(4)(5). Some studies have discriminated the origins of sesame seed and sesame oil by combining the quality components with the statistical method according to the origin of sesame seeds (6)(7)(8).…”
