Fig. 3 Disease incidence and gene expression analysis. a, b Levels of Foc TR4 infection in selected transgenic and WT banana plants throughout the 3-year field trial. a WT and RGA2 lines, and b WT and Ced9 lines. Wet seasons (November–April) are indicated. The number of biological replicates (n) of each independent line at the start of the trial is provided in Supplementary Table 1. Data points are percentage of biological replicates infected at time of assessment. *0.01 < p < 0.05, **0.001 < p < 0.01 at trial end (Tukey's HSD test). c, d Analysis of RGA2 mRNA expression levels in transgenic and WT banana plants. c Analysis of transgene (RGA2-Nos) expression levels using primers designed to amplify a 96 bp fragment spanning the RGA2transgene/Nos terminator junction. d Analysis of RGA2 transgene and endogenous mRNA expression levels using primers designed to amplify a 92 bp fragment of both the RGA2transgene and RGA2 endogenous sequences. All values are normalized expression levels expressed relative to line RGA2-3. WT GN; TR4-susceptible M. acuminata ssp. malaccensis(Mal-S) and TR4-resistant M. acuminata ssp. malaccensis (Mal-R). A single biological replicate was analyzed with three technical replicates (n = 3). Data are mean ± SEM Table 1. DPM25, Dwarf Parfitt Mutant; GCTCV, Giant Cavendish Tissue Culture Variants; GN, Grand Nain; HSD, honest significant difference; TR4, tropical race 4. Data are percentage of biological replicates infected at time of assessment. *0.01 < p < 0.05, **0.001 < p < 0.01 at trial end (Tukey's HSD test). Fig. 1 Transgene expression cassettes and Southern analysis of selected transgenic lines. a RGA2 and b Ced9 expression cassettes. LB, left border; RB, right border. Determination of transgene copy number in c RGA2 and d Ced9 transgenic banana lines by Southern blot analysis. Genomic DNA from WT, RGA2 and Ced9 lines was digested with HindIII and XmaI, respectively. DNA molecular weight marker II (Roche) reference is indicated on the right hand side Protein sequence alignment of the RGA2 transgene sequence from TR4-resistant M. acuminata ssp. malaccensis (Mal-R) and the three consensus RGA2 homologous sequences from WT GN. Amino acid differences are highlighted Fig. 2 Characteristic symptoms of Foc TR4 in susceptible and resistant banana. External symptoms and reddish-brown internal vascular discoloration of Foc TR4 in infected WT Cavendish a and b compared with resistant transgenic lines RGA2-3 c and d, and Ced9-21 eand f
