Phylogenetic and Expression Analyses of Peroxidases in lbf1 Mutants.

(A) Phylogenetic unrooted tree of Arabidopsis and flax peroxidase proteins. Branches marked by a dot correspond to individual peroxidase transcripts significantly more abundant (P value < 0.05, Bonferroni method) in inner (blue dot) or outer tissues (red dot) or less abundant in inner (pink dot) or outer tissues (green) of lbf1 mutant compared with the wild type.

(B) Heat map of transcript accumulation corresponding to flax peroxidases in clades A, B, and C containing known Arabidopsis lignin-related peroxidases.
