Expression patterns of OsHsp18.0 in SH5 and Nipponbare in response to Xoo infection and heat treatment. (a) The relative expression of OsHsp18.0 in SH5 and Nipponbare in response to Xoo strain Zhe173 infection. qRT-PCR was performed using total RNA isolated from inoculated plants at five-leaf stage. The expression level (arbitrary units) was normalized using β-actin as an internal reference, and the normalized expression level of OsHsp18.0 in Nipponbare under non-infected condition at 0 h was set as 1. (b) The relative expression of OsHsp18.0 in SH5 and Nipponbare in response to five Xoo strains at 5 dpi. Normalized mRNA level in Nipponbare at 0 d was arbitrarily set as 1. (c) The relative expression of OsHsp18.0 in rice leaves of Nipponbare and SH5 after treated with 45 °C. The normalized expression level in leaves of Nipponbare at 0 h was set as 1. Bars represent means (three replicates) ±SD.
