Phylotranscriptomics Reveals the Reticulate Evolutionary History of a Widespread Diatom Species Complex

Abstract: In contrast to surveys based on a few genes that often provide limited taxonomic resolution, transcriptomes provide a wealth of genomic loci that can resolve relationships among taxonomically challenging lineages. Diatoms are a diverse group of aquatic microalgae that includes important bioindicator species and many such lineages. One example is Nitzschia palea, a widespread species complex with several morphologically based taxonomic varieties, some of which are critical pollution indicators. Morphological di… Show more

“…Light microscopy (LM) counts distinguished strains based on their length, width, and fibula density features (Additional file 1: Table S2). These features overlapped with the morphometric ranges provided by Çiftçi et al [41], except for TCC907 (Additional file 1: Table S3). This strain is reported to be a recent putative hybrid, and it had many morphological deformities due to culture conditions.…”

“…The number of total clusters that we obtained after the removal of TCC13903 and the clusters that passed all filtering steps are listed in Table 1. TCC907 had the lowest average number of reads per cluster in the meta-reference, probably due to the higher genetic polymorphism of its allopolyploid genome [41].…”
