  <dc:description xmlns:ns0="xml" ns0:lang="en">The adaptive radiation of Bromeliaceae (pineapple family) is one of the most diverse  among Neotropical flowering plants. Diversification in this group was facilitated by  shifts in several adaptive traits or “key innovations” including the transition from C3 to  CAM photosynthesis associated with xeric (heat/drought) adaptation. We used  phylogenomic approaches, complemented by differential gene expression (RNA-seq)  and targeted metabolite profiling, to address the mechanisms of C3/CAM evolution in  the extremely species-rich bromeliad genus, Tillandsia, and related taxa. Evolutionary  analyses of whole-genome sequencing and RNA-seq data suggest that evolution of  CAM is associated with coincident changes to different pathways mediating xeric  adaptation in this group. At the molecular level, C3/CAM shifts were accompanied by  gene expansion of XAP5 CIRCADIAN TIMEKEEPER homologs, a regulator involved  in sugar- and light-dependent regulation of growth and development. Our analyses  also support the re-programming of abscisic acid-related gene expression via  differential expression of ABF2/ABF3 transcription factor homologs, and adaptive  sequence evolution of an ENO2/LOS2 enolase homolog, effectively tying  carbohydrate flux to abscisic acid-mediated abiotic stress response. By pinpointing  different regulators of overlapping molecular responses, our results suggest plausible  mechanistic explanations for the repeated evolution of correlated adaptive traits seen  in a textbook example of an adaptive radiation.</dc:description>
