Association of C3H12 with a bacterial resistance QTL. A, Colocalization of C3H12 and a minor resistance QTL against Xoo strain PXO61. B, Increased susceptibility to Xoo strain PXO61 was associated with suppression of C3H12 in C3H12-RNAi (38Ri) plants. neg, Negative transformant. Bars represent means (five replicates for lesion area and three replicates for gene expression) ± sd. The letter “a” above the bars indicates that a significant difference between transgenic plants and wild-type (WT) Minghui 63 was detected at P < 0.01. C, F2 plants carrying the C3H12 allele from Mudanjiang 8 were less susceptible to PXO61 than the plants carrying the C3H12 allele from Minghui 63 at relatively consistent genetic background for other resistance loci.
