  1. aPPR protein data of Arabidopsis are from Small and Peeters [92]. The PPR class represents the number contigs longer than 150 aa, which is the minimum length of PPR proteins identified in Arabidopsis. bThe number of total contigs and the number of intact contigs aligned to the reference sigma factors are shown. Intact contigs are those with start/stop codons on 5′ and 3′ ends, and without any internal stop codons.
