Analyses of rRNA and ribosomal proteins from wild type and wp1. A, rRNA analysis using Agilent 2100. RNA was isolated from 10-d-old wild-type seedlings (a), wp1w seedlings (b), wp1s seedlings (c), wild-type panicles (d), wp1w panicles (e), and wild-type roots as control (f). B, Western-blot analysis of chloroplast ribosomal proteins. Proteins were extracted from 10-d-old seedlings (a) and panicles (b). The proteins were hybridized with antibodies against RPL2, RPS3, and RPS18, respectively. Hsp90 was used as an internal control.
