Figure 1.
Allelic variants in the MdMYB44 promoter are associated with fruit malate content. A Nine genotypes formed by the SNP T/− and SNP A/G combinations in the Malus accessions. B, Boxplots showing the analysis between the genotypes (G1, G2, G3, G4, G5, G6, G7, G8, and G9) in the MdMYB44 promoter and fruit malate content in 135 Malus accessions. The instructions of boxplots were provided, and “n” represents number of individuals in each genotype (G1−G9). C, Transcription profiles of MdMYB44 in the F1 progenies from “Jonathan” × “Golden Delicious” with three genotypes (G1, G2, and G3) during apple fruit development. D, Transcription profiles of MdMYB44 in the F1 progenies from “Zisai Pearl” × “Red Fuji” with two genotypes (G4 and G5), parent “Zisai Pearl” with the genotype G7, and parent “Red Fuji” with the genotype G2, during fruit development. E, Correlation analysis between MdMYB44 expression levels and fruit malate content. Values represent the mean ± SE in C, D, and E. The * indicates significantly different values (P < 0.05); ** indicates significantly different values (P < 0.01).
