英文摘要Key messageTFL1homologCorcanTFL1suppresses the initiation of inflorescence development and regulates the inflorescence morphology inCornus canadensis.AbstractIn flowering plants, there is a wide range of variation of inflorescence morphology. Despite the ecological and evolutionary importance, efforts devoted to the evolutionary study of the genetic basis of inflorescence morphology are far fewer compared to those on flower development. Our previous study on gene expression patterns suggested a CorTFL1-CorAP1 based model for the evolution of determinate umbels, heads, and mini dichasia from elongated inflorescences in Cornus. Here, we tested the function of CorcanTFL1 in regulating inflorescence development in Cornus canadensis through Agrobacterium-mediated transformation. We showed that transgenic plants overexpressing CorcanTFL1 displayed delayed or suppressed inflorescence initiation and development and extended periods of vegetative growth. Transgenic plants within which CorcanTFL1 had been down-regulated displayed earlier emergence of inflorescence and a reduction of bract and inflorescence sizes, conversions of leaves to bracts and axillary leaf buds to small inflorescences at the uppermost node bearing the inflorescence, or phyllotaxy changes of inflorescence branches and leaves from decussate opposite to spirally alternate. These observations support an important role of CorcanTFL1 in determining flowering time and the morphological destinies of leaves and buds at the node bearing the inflorescence. The evidence is in agreement with the predicted function of CorTFL1 from the gene expression model, supporting a key role of CorTFL1 in the evolutionary divergence of inflorescence forms in Cornus.
