Distribution of the peroxisomal transporter involved in the uptake of fatty acids, ATP, and NAD in green plants. Homologs genes for CTS (At4g39850), PNC1 (At3g05290), PNC2 (At5g27520), and PXN (At2g39970) were identified in 22 fully sequenced plant genomes from PLAZA 2.0 (http://bioinformatics.psb.ugent.be/plaza) using BLASTP (Altschul et al., 1997). For rice only Oryza sativa ssp. japonica was taken into account. The reciprocal hit was chosen if it was in both directions among the three best hits in the other genome. As a cut-off value we used a normalized sequence identity greater than 25%.
