The structure and expression characterization of Xa7. (a) Gene structure of Xa7. The schematic map shows the EBEAvrXa7 (110–136 bp upstream of the ATG start code), the coding region (black rectangle), and the 5′ and 3′UTR regions (gray rectangles). The numbers indicate the distance from ATG code initiation site for each element or substructure. (b) The deduced amino acid sequence of XA7. The transmembrane helices are underlined. (c) Expression pattern of Xa7 gene after inoculation with Xanthomonas oryzae pv. oryzae (Xoo) strain PXO86 and PXO99, respectively. The average expression level of Xa7 in IRBB7 at 0 d was set as “1”. The expression levels of other time point were used to compare with that of 0d. The data represents the mean ± standard deviation (n = 3 replicates). Student’s t-test analysis indicates a significant difference (compared with control, ** P < 0.01)
