Phylotranscriptomics reveals the phylogeny of Asparagales and the evolution of allium flavor biosynthesis.

ABSTRACT: Asparagales, the largest monocot order, is renowned for its ecological, economic, and medicinal significance. Here, we leverage transcriptome data from 455 Asparagales species to explore the phylogeny of Asparagales. Moreover, we investigate the evolutionary patterns of the genes involved in allium flavor formation. We not only establish a robust bifurcating phylogeny of Asparagales but also explore their reticulate relationships. Notably, we find that eight genes involved in the biosynthesis of allium flavor compounds underwent expansion in Allium species. Furthermore, we observe Allium-specific mutations in one amino acid within alliinase and three within lachrymatory factor synthase. Overall, our findings highlight the role of gene expansion, increased expression, and amino acid mutatio
