Figure 6From: Gene expression analysis of flax seed developmentPutative 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-ZIPIII family and AS1) and abaxial (YABBY and KANADI families) gene expression establishes organ polarity. EST distribution of flax unigenes used to compile this graph is listed in Additional File 2.Back to article page
