Abstract

Eukaryotic genes can be classified into intronless (no introns), intron-poor (three or fewer introns per gene) or intron-rich. Early eukaryotic genes were mostly intron-rich, and their alternative splicing into multiple transcripts, giving rise to different proteins, might have played pivotal roles in adaptation and evolution. Interestingly, extant plant genomes contain many gene families with one or sometimes few sub-families with genes that are intron-poor or intronless, and it remains unknown when and how these intron-poor or intronless genes have originated and evolved, and what their possible functions are. In this study, we identified 33 such gene families that contained intronless and intron-poor sub-families. Intronless genes seemed to have first emerged in early land plant evolution, while intron-poor sub-families seemed first to have appeared in green algae. In contrast to intron-rich genes, intronless genes in intron-poor sub-families occurred later, and were subject to stronger functional constraints. Based on RNA-seq analyses in Arabidopsis and rice, intronless or intron-poor genes in AP2, EF-hand_7, bZIP, FAD_binding_4, STE_STE11, CAMK_CAMKL-CHK1 and C2 gene families were more likely to play a role in response to ...Continue Reading
