Structural characteristics of the 1581 putative PPR sequences identified in A. angustifolia. A Frequency of the length in amino acid residues of the putative PPR sequences. B Pie chart showing the different subfamilies and classes into which the PPR family is subdivided as well as the number of putative PPR sequences that each one houses. C Frequency of the number of PPR motifs detected per sequence and separated according to the P and PLS subfamilies. The nucleotide sequence data of the 1581 PPRs for this study are deposited at NCBI in the nucleotide database under accession numbers OM156485 - OM158065
