Table 1 QTL associated with tocopherol concentration or content using F2 seed and F2 plant populations.

From: Genetic variation of γ-tocopherol methyltransferase gene contributes to elevated α-tocopherol content in soybean seeds

  1. QTLs are detected using multiple QTL mapping (MQM) method in MapQTL 5. Permutation test (1000 times) was performed to determine genome wide significance threshold level (P < 0.05).
  2. aα% represents α-tocopherol concentration, γ% represents γ-tocopherol concentration, δ% represents δ-tocopherol concentration, α-content represents α-tocopherol content (μg per 100 mg dry weight seeds), and γ-content represents γ-tocopherol content (μg per 100 mg dry weigh seeds). bLOD means logarithm of odds, the peak of LOD value in the QTL range. cPVE means the percentage of phenotypic variance explained for the trait. dPositive values of additive effect (Add) mean the increased effect for the QTL was caused by KAS allele.
