Geographical isolation facilitates the emergence of distinct phenotypes within a single species, but reproductive barriers or selection are needed to maintain the polymorphism after secondary contact. Here, we explore the processes that maintain intr

Comparative transcriptomics show that the initial emergence of C4 photosynthesis in Alloteropsis semialata coincides with few changes in gene expression within mature leaves, with secondary adaptation occurring in geographically isolated populations.
