Fine mapping of qSER-7. a The genetic linkage map of qSER-7 region on chromosome 7. The number between markers indicate genetic distance in centimorgans. b Fine mapping of the qSER-7 locus with six homozygous recombinants. Genotypes and phenotypes of homozygous recombinant lines(R1-R6) were performed from BC4F4 population. The qSER-7 was narrowed down to a 28.4-kb interval between the markers RM3859 and Indel4374. Black and white bars indicate homozygous for II-32B and Huhan 1B, respectively. The number between markers indicate physical distance. The data represent the mean ± SD (n = 10), ** P ≤ 0.01, t-test. c Candidate region of the qSER-7 locus and the annotated genes in the rice genome annotation database (http:// rice.plantbiology.msu.edu/, MSU- version_7.0)
