Amino acid sequence alignment of two putative nuclear-encoded rpl23 transcripts in Geranium maderense. The 5′-plastid transit peptide and the cleavage site indicated by the black bar were predicted by TargetP (Nielsen et al. 1997; Emanuelsson et al. 2000). The conserved domains of the 50S and 60S ribosomal proteins L23 indicated by gray bars were predicted by NCBI Conserved Domain Database (Marchler-Bauer et al. 2015). The BLOSUM62 protein substitution matrix with a threshold of one was used to assess similarity between residues. The identical and 60–99% similarity residues were highlighted in black and gray, respectively.
