Analysis of OsXTH19 RNAi-expressing and OsXTH19-over-expressing transgenic plants. (A) Expression of OsXTH19 in 7-d-old rice seedling. OsXTH19 transcript levels were examined by real-time RT-PCR in wild-type (WT), OsXTH19 RNAi (lines R3, R4 and R10), and OsXTH19-over-expressing (OX15 and OX18) transgenic plants. Relative transcript levels of OsXTH19 compared with those for the WT plant are shown. Results represent the means ± s.d. of triplicate biological samples. (B) Comparison of the heights of WT, OsXTH19 RNAi and OsXTH19-over-expressing transgenic plants grown for 28 d under normal growth conditions. Results represent the means ± s.d. of eight plants for each line.
