Disentangling sources of gene tree discordance in phylogenomic datasets: Testing ancient hybridizations in Amaranthaceae s.l. Systematic Biology. Open Access
  • Ancient and rapid radiations can be difficult to resolve. We present a case where commonly used methods for detecting reticulate evolution are unable to distinguish ILS, uninformative gene trees, versus true reticulation events, even with genome scale data.
  • Our results support a broadly circumscribed Amaranthaceae s.l. that includes Chenopodiaceae.

  • ​De novo transcriptome assembly is error-prone, and any downstream analysis is probably worse, especially in plants where polyploidy is common. But how bad it is? We found that unless the polyploidy event happened less than ~10 or so million years ago, gene expression analyses using de novo assembled transcriptomes are actually not that bad.

  • Final chapter of Ya's Ph.D. dissertation. Ya spent two years cloning low-copy nuclear genes but got very little resolution. Allopolyploidy, rapid radiation, hybridization, and non-monophyly of morphologically well-defined unites--all the taxonomic challenges in one small clade. Nonetheless some interesting patterns emerged from chloroplast markers. ​​
