Figure Lengend Snippet: Mean, standard deviation, and minimum and maximum values of tocopherols and tocotrienols in 230 lines of Mv Toborzó/Tommi population in 2 years (2014 and 2019).

Article Snippet: Commercial tocopherols (α-, β-, γ-, and δ-tocopherol; Merck, Darmstadt, Germany) were dissolved in ethanol (purity > 99.5% for spectrophotometric purposes), and this concentrate was used to identify and quantify the components.

Figure Lengend Snippet: Principal component analysis based on the content and composition of tocols in the grain. AT = α-tocopherol, ATT = α-tocotrienol, BT = β-tocopherol, BTT = β-tocotrienol, GT = γ-tocopherol, tocol = total tocol content, and TKW = thousand-kernel weight (where the most determinant traits contributing to Factor 1 were BT (−0.8607), BTT (−0.9239), and tocol (−0.9814), while it was AT (−0.6417) and ATT (−0.8032) for Factor 2).

Figure Lengend Snippet: Pie diagrams of the relative contribution of genotype (G), environment (E, 2 years), and genotype × environment interaction (G × E) to the total sum of squares for the tocol content and composition of bread wheat, where ( a ) AT = α-tocopherol, ( b ) ATT = α-tocotrienol, ( c ) BT = β-tocopherol, ( d ) BTT = β-tocotrienol, ( e ) tocol = total tocol content, and ( f ) TKW = thousand-kernel weight (Martonvásár, 2014 and 2019, n = 230).

Figure Lengend Snippet: HPLC chromatographic analysis of ethanol extracts of wild-type Synechocystis sp. PCC 6803, slr1736 null mutant, and slr1736 null mutant complemented with HPT1. A, Wild-type Synechocystis sp. PCC 6803 transformed with control vector. Peak 4 corresponds to α-tocopherol at 4.6 min. B, slr1736 null mutant lacking tocopherol peak at 4.6 min. C, slr1736 null mutant complemented with Arabidopsis HPT1 with tocopherol signal apparent at 4.6 min. A compound eluting at 8.5 min represents the tocol internal standard (peak 5). Peak 1 corresponds to the solvent front, and peaks 2 and 3 are two unknown compounds.
