Genomics / Proteomics Yang, Ya [1], Moore, Michael [2], Brockington, Samuel [3], Smith, Stephen [4]. Functional and spatial heterogeneity of gene family evolution in non-model species: three strategies using Caryophyllales as an example. RNA-seq offers the ability to explore the patterns and drivers of plant diversification on a scale never before possible. However, most studies so far have been focusing on either resolving phylogenetic relationships, or exploring molecular evolution in a small number of gene families. Using a data set of over 200 transcriptomes and three genomes across Caryophyllales, including 104 newly sequenced transcriptomes, we found evidence for at least 21 ancient genome duplication events. From the data set of >15,000 genes per species, we discovered that many gene duplication events were associated with key adaptive trait changes such as the de novo assembly of the betalain synthesis pathway. Here we discuss three alternative strategies for interrogating transcriptomic and genomic data sets for large-scale patterns of gene family evolution: baited, all-by-all, and genome walking, and discuss moving forward putting gene family evolution into both functional and spatial perspectives.
