  • The different entries represent putative Arabidopsis CYP703A2 orthologs that were identified in EST databases encompassing algae, bryophytes, gymnosperms, monocots, and eudicots. The strong bias for expression in flowers buds, male organs, and tissues before anthesis is apparent. Analyses at the genome level in C. reinhardtii and P. patens are shown at top.

  • a These ESTs correspond to O. sativa CYP703A3.

  • b These ESTs correspond to Arabidopsis CYP703A2.

  • c These ESTs correspond with 99.6% identity to L. japonicus CYP703A7.
