Genetically resolving the
l-D1
locus in Upland cotton. (A) Genetic mapping of
l-D1
locus based on biparental mapping. (B) Orthologous mapping of
the l-D1
locus to the sequenced D genome donor (G. raimondii)
chromosome 2 (337 kb, 34 putative genes) (30), and (C) shuttle mapping using the orthologous
laciniate
(l-A2)
locus from diploid donor species G. arboreum (112 kb, 10
putative genes) (21).
(D) Fine mapping of
l-D1
locus using an association mapping panel and two sets (BC8 and
BC3) of isogenic lines (52 kb, putative four genes).
(E) Association analysis statistics, adjusting for
population structure for variants within candidate gene region of
l-D1
locus.
