Transcriptional Downregulation of rpL32 in Rice Figure 1. Northern blot analysis of rpL32_8.1 under salt stress. (A) Pokkali shoot (B) PB1 shoot (C) Pokkali root (D) PB1 root. t0.0 to t24.0 indicate the time of treatment (in h) with 200 mM NaCl ranging from 0 h to 24 h. The graphical representation of the data was deduced by normalizing the densitometric intensity of rpL32 genes on the blot with that of 28S rRNA in the corresponding lane of the EtBr gel. doi:10.1371/journal.pone.0028058.g001 Figure 2. Northern blot analysis of rpL32 genes located on chromosome 9 under salt stress. (A) rpL32_9.3, (B) rpL32_9.2, (C) rpL32_9.1. t0.0 to t24.0 indicate the time after treatment of the Pokkali rice seedlings with 200 mM NaCl ranging from 0 to 24 h. All analyses were done as mentioned for Figure 1. doi:10.1371/journal.pone.0028058.g002 PLoS ONE | www.plosone.org 3 November 2011 | Volume 6 | Issue 11 | e28058
