ALT A nine-part graphic showing the use of untargeted metabolomics to analyze metabolite abundance in four genetically distinct diploid and neo-autotetraploid pairs of Spirodela polyrhiza. The findings revealed that while whole genome duplication (WGD) typically increases cellular metabolite levels, the relative abundance per biomass does not change significantly due to increased cell size associated with WGD. The PCA plots, heatmaps, and Venn diagrams indicate that variations in metabolite abundance are primarily driven by strain-specific differences, rather than by changes in ploidy alone. However, WGD still exerts a discernible quantitative and qualitative influence on the phytochemical composition of these strains, each with potential ecological implications.

ALT The graphic shows how read mapping and the called allele dosage in allo- and autopolyploids differ due to the structure of the reference genome. Reads (gray) are shown aligning the reference genome (black), with alleles for the focal variant in pink or yellow. (A) In an allotetraploid with two subgenomes (subgenome K in light gray and subgenome N in dark gray), reads are mapped to one haplotype of each parental subgenome, and diploid genotypes are called. (B) In an autotetraploid with no preferential pairing, all reads are mapped to a single haplotype. Here, reads are aligned to a haplotype carrying the yellow A allele at the focal variant.
