2003) and interestingly, auxin appears to play an important role in establishing a part of this growth pattern. e. , 2010). , 2010). The process of leaf serration shows many similarities to that of leaflet formation in dissected leaves. For example, leaf dissection in Cardamine hirsuta also relies on the activity of CUC boundary-specifying genes in the area delimiting leaflet primordia and on the activity of KNOX genes at the leaflet initiation position, which cause a delay in cell differentiation relative to cell proliferation.

2008; Nole-Wilson and Krizek, 2006). SPT, which has been mentioned above for its role in other aspects of gynoecium morphogenesis, is also a major factor in the formation of carpel marginal tissues. In spt mutants, the stigma and the style are reduced, the septum is distorted and the transmitting tract is not properly formed (Alvarez and Smyth, 1999). , 2001). Some other factors have also been specifically related to transmitting tissue development. , 2007). HEC proteins are able to physically interact with SPT in yeast two hybrid assays, so it has been suggested that HEC and SPT function together in this process.

In fact, in the double mutant apetala2 (ap2) ag, organs with carpel characteristics still develop in the first whorl of the flower (Bowman, 1991). This observation led to the conclusion that other genes involved in carpel identity were present and were, like AG, negatively regulated by the A-class gene AP2. D). In the quadruple ap2 ag shp1 shp2 mutant, all carpelloid structures disappear. , 2001). Two other putative transcription factors required for the development of carpel tissues are encoded by the bHLH gene SPT and the YAB gene CRABS CLAW (CRC), which seem to act downstream of AG/SHP.
