Expression pattern of tissue-specific ncRNAs and their neighboring genes by Northern blot and semi-quantitative RT-PCR. (a) Expression pattern of three C/D box snoRNAs (Zm-6, Zm-18, and Zm-38) and one unclassified ncRNA (Zm-73) in different tissues of maize by northern blot. (b) Expression pattern of four tRNAs in different tissues of maize by northern blot. (c) Expression pattern of the neighboring genes of Zm-6, tRNALeu (TAG), and tRNASer (GGA) in different tissues of maize by semi-quantitative RT-PCR. R, S, B, SP, FL, Sa, H, and K representing the root, stem, blade, sheath & petiole, flag leaf, stem apex, hypocotyl, and developing kernel, respectively. 7SL was used as an internal control for ncRNAs (a) and (b). The tubulin gene was used as an internal control for neighboring genes (c)
