Major-Effect Alleles at Relatively Few Loci Underlie Distinct Vernalization and Flowering Variation in Arabidopsis Accessions
Figure 2
Fine-mapping and allelic analysis of the QTL on chromosome 1.
(A) Fine-mapping of the QTL – the later flowering time variation co-segregated with marker 538D and 12INS. (B) FAS1 expression in Col-0 and two recombinants plants Rec17 and Rec18. (C) FT expression in Col-0, Rec17 and Rec18. FT expression level was normalized to UBC. (D and E) Segregation analysis of the F2 population obtained from Rec17 (D) and Rec18 (E) crossed to Col-0 respectively. Error bars in (B) and (C) show S. D. from three experimental replicates, in (D) and (E) shows S. D. of at least 20 individuals.
