Figure 5. Phenotypes and DI values for introgressed lines.

(A and B) Segregating phenotypes obtained from crossing CYC^majRAD^maj/CYC^chaRAD^cha to the double mutant cyc rad/cyc rad. Yellow dotted line shows where the rims of the lateral and dorsal tube meet and highlights the difference between the effect of A. charidemi alleles (left) and those of A. majus (right). (C) DI _cor values for the genotypes in (A and B). Note that the A. charidemi alleles give a higher DI _cor value than the A. majus alleles (two-sided t-test _114.87df = 7.24, p<0.001). (D) DI _lat values for progeny obtained from CYC^majRAD^maj/CYC^chaRAD^cha crossed to the double mutant cyc rad/cyc rad. The A. charidemi alleles give a higher DI _lat value than the A. majus alleles (two-sided unpaired t-test ₅₀₈df = 6.73, p<0.001). (E) DI _lat values for progeny from a plant heterozygous for a recombinant allele (CYC^majRAD^maj/CYC^chaRAD^maj) crossed to the double mutant cyc rad/cyc rad. Plants carrying the CYC^cha allele have a higher DI _lat value than those carrying the CYC^maj (two-sided t-test _202.37df = 3.14, p = 0.002). (F) DI _lat values for progeny from a plant heterozygous for a recombinant allele (CYC^majRAD^maj/CYC^majRAD^cha) crossed to the double mutant cyc rad/cyc rad. Plants carrying the RAD^cha allele are not significantly different from those carrying RAD^maj (two-sided t-test _202.37df = 3.14, p = 0.002). Bars indicate standard errors.
