Transcription profiling of Arabidopsis wild type, tcp13, tcp14, tcp13/+ tcp14/+, and tcp13 tcp14 plants to identify targets of the mci genes.

ABSTRACT: In Antirrhinum, the equivalent mutant to the Arabidopsis cuc1 cuc2 double is called cup. We have cloned CUP and shown that it encodes a NAC-domain transcription factor homologous to CUC1 and CUC2. Yeast two-hybrid analysis shows that CUP interacts with TIC, an Antirrhinum TCP transcription factor. Moving back to Arabidopsis, the closest homologues to TIC encode TCP factors TCP13 and TCP14 which, we have now shown, also interact in two-hybrid experiments with CUC1 and CUC2. We have identified insertions in both TCP13 and TCP14. CUP, CUC1 and CUC2 play a role in the establishment of boundaries between lateral organs. As evolutionarily conserved interactors, we expect TCP13 and TCP14 to act in the same process. Homozygous tcp13 mutant flowers show mixed cell identity (mci) with the boundaries
