ID Chromosome Marker Interval QTL Position in cM QTL Position Range in cM High-Effect Allele QTL Pvalue h2of QTLs Comparison to cotyledon opening QTL
Bay x Sha population1
S.BS3_10 3 ATHCHIB2-MSAT3.19 10.8 4 - 17.8 Bay P = 6.9 × 10-4 0.016 Same locus; higher variation allele has lower effect on opening.
Ler x Col population2
S.LCo2_45 2 C2_074-C2_075 45.6 41 - 54     Locus is the same or nearby (intervals overlap), has significant UV-B variation effect but no additive main effect. Ler allele median variance is high in +UV-B round 1 (P = 0.0039), and Ler allele median variance is low in -UV-B round 2 (P = 0.016).
S.Lco4_57 4 C4_089-C4_090 57.1 55 - 58 Col P = 3.5 × 10-5 0.043 New locus, no UV-B-specific effect.
