Map-based cloning of GLR1 . (a) The GLR1 locus was mapped in chromosome 5 between markers M1 and M2. Recombinants were identified from 1,447 F₂ glabrous plants. (b) Fine mapping of the GLR1 locus. The GLR1 locus was narrowed to a 21-kb genomic DNA region between markers M6 and M7. (c) The LOC_Os05g02720 (green) and LOC_Os05g02730 (red) are predicted in the candidate region. The annotated gene of LOC_Os05g02730 consists of two exons and one intron. (d) The relative expression levels of LOC_Os05g02720, LOC_Os05g02730 and LOC_Os05g02754 in young panicles of NIL^GLR1 and NIL^glr1 plants (T-test, P<0.05).
