Gene family evolution in the carnivorous clade of Caryophyllales.

Carnivorous plants have long been a fascination to both scientists and the general public. Carnivory appears across the tree of life multiple times, with an estimated nine independent origins of this adaptation. Obtaining nitrogen through animal sources allows these plants to survive in nutrient poor soil. However, this requires investment in trapping and digestive mechanisms. With a single origin and multiple different mechanisms of capturing prey, the carnivorous clade in Caryophyllales represents one of the most species rich developments of carnivory. Between the diverse morphology and wide distribution, this clade provides a rich evolutionary history for studying carnivory. Here, we use transcriptome data to help resolve some of the major family relationships of this clade and further analyze gene and genome duplications that are present in this group. We also use a time series data set consisting of Drosera binata and Nepenthes alata, to identify genes that change in expression between life stages and gene family evolution associated with this change.
