TL;DR:
The study found a clear correlation between the expression patterns of CorTFL1 and CorAP1 and the inflorescence architecture in a natural system displaying closed inflorescences and proposes that a TFL1-like and AP1- like gene-based model may explain variation of closed inflorescenceences in Cornus and other lineages.
