Expression pattern of
. (A) Northern analysis of OsPUB15 in different tissues of rice cultivars TP309 and Digu. The total RNAs extracted from various rice tissues were hybridized with 32P-labeled OsPUB15 probe, rRNA signals were used as a sample loading control. R, S, L, YP and MP denote root, stem, leaf, young panicle and mature panicle, respectively. (B) qRT-PCR analysis of OsPUB15 expression profiling in TP309 and Digu at 0, 1, 2, 3, 4, 5 and 6 days post inoculation (DPI) with the blast strain ZB15. The expression level of OsPUB15 at 0 day was set as 1.0. The expression level of rice ACTIN1 gene was used as an internal control for normalization of the data. Values are means ± SDs of three biological repeats.
