Table III. Evolutionary conservation of putative core dPCD markers.
% ID reflects the sequence similarity between the Arabidopsis gene and the best blast hit in vertebrates. All genes belong to PLAZA 3.0 orthologous gene families that encompass the Magnoliophyta (RNS3, BFN1, and MC9) or Viridiplantae (SCPL48 and PASPA3) clade (not shown). AGI, Arabidopsis Genome Initiative gene code; HOM, homologous; Nuclease PA3-like, a predicted protease (GenBank accession number XP_005974529.1); CPVL, carboxypeptidase, vitellogenic-like.
