Introns are integral elements of eukaryotic genomes that perform various important functions and actively participate in gene evolution. We review six distinct roles of spliceosomal introns: (1) sources of non-coding RNA; (2) carriers of transcription regulatory elements; (3) actors in alternative and trans-splicing; (4) enhancers of meiotic crossing ...

AbstractIntrons of plant tubulin genes are useful molecular tools to study IME (Intron Mediated Enhancement of gene expression) and to define plant genetic and evolutionary relationships through ILP (Intron Length Polymorphism). Here we show that the intron present within the 5′UTR sequence of some rice β‐tubulin genes can sustain IME in rice ...

Accumulating evidence that introns are highly restricted in their phylogenetic distribution strongly supports the view that introns were inserted late in eukaryotic evolution into preformed genes and, hence, that exon-shuffling played no role in the assembly of primordial genes.

Intron Biology, Focusing on Group II Introns, the Ancestors of Spliceosomal Introns
2015Self-splicing group II introns are large ribozymes and mobile retroelements initially identified in the mitochondrial and chloroplast genomes of lower eukaryotes and plants and subsequently found in bacteria and archaea. Group II introns display structural, functional and mechanistic similarities to eukaryotic pre-mRNA nuclear introns, which may have ...

Intron Splicing and Intron-mediated Enhanced Expression in Monocots
1992Publisher Summary The basic recognition sites (5 ‘ , 3‘, and branchpoint) for intron splicing in plants do not differ significantly from those of vertebrates. It is also demonstrated, by the mutations of splice-site recognition sequences, that the 5 ‘ GT or 3‘ AG dinucleotides are essential for proper splicing in monocots.
