AS changes in response to wheat polyploidization. A, The number of AS events in TAA10, ETW, TQ18, and XX329. Allohexaploid XX329 was resynthesized by the maternal parent ETW and the paternal parent TQ18. ETW was ploidy-reversed from hexaploid cultivar wheat TAA10 with high karyotype stability, produced by recurrent backcrossing. B, The number of polyploidization-responsive AS events in wheat, including lost AS events, new AS events, QDASE, and ATI. C, Comparison of density distribution of PSI before and after wheat polyploidization. P value was calculated using the Kolmogorov–Smirnov test. Blue, before polyploidization; red, after polyploidization. D, GO enrichment analysis of ASGs responsive to polyploidization. The color scale from white (low) to dark red (high) represents differential log₁₀(P value) of GO enrichment, and only significantly enriched terms (P < 0.05) are indicated.
