Putative flax unigenes representing organ polarity transcription factors. Organ polarity transcription factor ESTs are most abundant during cotyledon primordia differentiation of heart-stage embryos. Adaxial (HD-ZIPIIIfamily andAS1) and abaxial (YABBYandKANADI家庭)基因表达establishes organ polarity. EST distribution of flax unigenes used to compile this graph is listed in Additional File2.
