> Divergence in AS variants of gene pairs presents an important layer of gene regulation, as reported35–38, and thus provides a genetic basis for species evolution and new species formation.
>
> This subfunctionalization or neofunctionalization of duplicated genes provides genetic novelty and a basis for species evolution and new species formation
>
> Gene expression variation may contribute to an increased complexity of regulatory networks after polyploidization.

>
> Alternative splicing can enhance transcriptome plasticity and proteome diversity.
>
> Estimates have suggested that ∼22%–30% of *Arabidopsis* intron-containing genes are alternatively spliced
>
> We predict that at least ∼42% of intron-containing *Arabidopsis* genes are alternatively spliced. This estimate is significantly higher than previous estimates based on cDNA/EST sequencing.
>
> Extensive Divergence in Alternative Splicing Patterns after Gene and Genome Duplication During the Evolutionary History of Arabidopsis
>
> Genome duplication (polyploidy) has been a common phenomenon among eukaryotes of various groups, including plants, animals, and some single-celled eukaryotes.
>
> Despite the importance of AS to gene expression, the conservation of AS patterns after WG duplication remains unknown, and AS events for a sizable set of duplicated gene pairs have not been examined and compared in plants
>
> By comparing each subgenome in tetraploids with its extant diploid progenitor

## Identification and analysis of alternative splicing events in Phaseolus vulgaris and Glycine max

> Animals tend to have very large introns and therefore the splicing machinery recognizes exons (exon definition) while in plants the spliceosome recognizes introns (intron definition) \[28].
