TCP transcription factors
TCP functions
Known functions indicate that TCPs are regulators of growth: Outgrowth of branches in maize (tb1) Limiting growth of flower parts, causing flower
asymmetry (cycloidea and dichotoma in Antirrhinum)
Control of leaf curvature (cincinnata in Antirrhinum)
Suggested to regulate transition from mitosis to expansion by interaction with cell cycle gene promoters

Study of TCP gene function in fruit development
Modification of expression of selected genes by (early fruit specific) ectopic expression or knock-down by RNAi/amiRNA
Mapping of interactions between TCP proteins as well as between TCP proteins and other TFs (targetted/non-targetted)
Activity of the TPRP promoter in fruit
TPRP promoter works well untill at least mature green stage; 2A11 promoter is considered as alternative for later stages
Early stages
Mature green Breaker Ripe fruit
