Map position of teosinte branched1
--John Doebley, Pamela vander Weil and Adrian Stec
We mapped teosinte branched1 (tb1) relative to seven molecular
marker loci that are near it on the long arm of chromosome 1. The mapping
population was based on a cross of W22 by a tb1-ref/tb1-ref homozygous
plant. The F1 from this cross was backcrossed to a tb1-ref/tb1-ref
plant. A total of 232 backcross plants were assayed. The tb1 stock
was given to us by Charles Burnham. Locus order and recombination fractions
were determined using computer program MAPMAKER Macintosh version 2.0.
The map with recombination fraction between loci is shown below:
