The relative expression levels of candidate genes and their KASP markers. a-c The expression and KASP result of Zm00001d039769. d-f The expression and KASP result of Zm00001d039913. a and d The relative expression levels of candidate genes for the two parents. Three independent experiments each using three biological replicates were used to generate these data. b and e Genotyping with KASP markers designed for each candidate gene. c and f The genotype of two KASP markers and their respective associations with fracture angle phenotype in the F2:3 population. * and ** denote significance at the level of 0.05 and 0.01, respectively
