Figure 4- Natural Variation in COR28 is associated with
covariation in period and flowering time
The SNP in COR28 associated with period variation causes a
tryptophan (W) to serine (S) amino acid change within the second exon
(A). Accessions carrying the 58S allele had periods 1.29h longer on
average than those with the 58W allele based on the 191-accession data
from this study (B). Out of the 191 accessions originally phenotyped, 16
had the 58S allele (red triangular points). Globally, 5 further 58S
accessions were identified (orange triangles) and all were found in the
south of Sweden (C). Accessions carrying the 58S allele also had
flowering times delayed by 89.23 days compared to those carrying the 58W
allele (data shown is based on flowering times from plants grown under
Swedish conditions previously published in Li et al. 2010 (D).
