Figure 5From: Applying genotyping (TILLING) and phenotyping analyses to elucidate gene function in a chemically induced sorghum mutant populationPhenotype of the bmr mutants. A. A section of the leaf blade from BTx623, P5A3, and P7H6. B. Cross section of young stems before histochemical staining showing the light brown color in bmr mutants. Free-hand sections (~200 μm thickness) were prepared with a razor blade. C. The same section as in B after histochemical staining for lignin with acidified phloroglucinol showing the reduction in lignin in both mutants. The pictures were arranged as wild-type BTx623, P5A3, and P7H6 from left to right.Back to article page
