Introns are ubiquitous features of all eukaryotic cells. Introns need to be removed from nascent messenger RNA through the process of splicing to produce functional proteins. Here we show that the physical presence of introns in the genome promotes cell survival under starvation conditions. A systematic deletion set of all known introns in budding yeast genes indicates that, in most cases, cells with an intron deletion are impaired when nutrients are depleted. This effect of introns on growth… 
Intron-mediated induction of phenotypic heterogeneity
TLDR
It is shown that introns can mediate inducible phenotypic heterogeneity that confers a clear fitness advantage and suggest that duplicated ribosomal protein genes in yeast contribute to resolving the evolutionary conflict between precise expression control and environmental responsiveness.
1 Intron-mediated induction of phenotypic 2 heterogeneity 3
TLDR
Differential intron-mediated regulation of RP genes thus provides a way to diversify the population when starvation looms in natural environments and suggests that duplicated RP genes in yeast serve to resolve the evolutionary conflict between precise expression control and environmental responsiveness.
Ribosomal intron-mediated switch governs yeast survival in starvation
TLDR
This work has found that osmotic stress leads to bimodal expression of the small ribosomal subunit protein Rps22B mediated by intron retention in its transcript, and suggests that duplicated RP genes serve to resolve the evolutionary conflict between precise expression control and environmental responsiveness.
Gene Architecture Facilitates Intron-Mediated Enhancement of Transcription
TLDR
This review highlights several potential mechanisms through which looping interactions may enhance transcription, and suggests that the splicing-facilitated changes in gene architecture may play a critical role in regulation of transcription in yeast as well as in higher eukaryotes.
Intronic RNA: Ad'junk' mediator of post-transcriptional gene regulation.
First Come, First Served: Sui Generis Features of the First Intron
TLDR
Recent progress in the underlying mechanisms of intron function is reviewed by focusing on unique features of the first intron that is located in close proximity to the transcription start site, which includes the distinct deposition of epigenetic marks and nucleosome density on thefirst intronic DNA sequence.
Intron distribution and emerging role of alternative splicing in fungi.
TLDR
The intronic landscape in fungi is described and the newly discovered functions of alternative splicing in various cellular processes are presented to outline areas particularly in pathogenesis and clinical drug resistance for future studies that could lead to the development of much needed new therapeutics.
Transcriptional regulation of genes bearing intronic heterochromatin in the rice genome
TLDR
This study investigates the genome-wide distribution of intronic TEs and their epigenetic states in the Oryza sativa genome and demonstrates that heterochromatin is a common epigenetic feature associated with actively transcribed genes in the rice genome.
Splicing modulators elicit global translational repression by condensate-prone proteins translated from introns
TLDR
Creating an overburden of condensate-prone proteins derived from introns represses translation and prevents further production of harmful truncated proteins, and appears to contribute to the antiproliferative and proapoptotic activity of splicing modulators.

Deletion of many yeast introns reveals a minority of genes that require splicing for function.
TLDR
It is shown that although the presence of introns may optimize gene expression and provide benefit under stress, a majority of intrins could be removed with minor consequences on growth under laboratory conditions, supporting the view that many introns could be phased out of Saccharomyces cerevisiae without blocking cell growth.
Introns: The Functional Benefits of Introns in Genomes
TLDR
The existence throughout the long evolutionary history is explained, only if selective advantages of carrying introns are assumed to be given to cells to overcome the negative effect of introns.
The intronome of budding yeasts.
Genome-wide bioinformatic and molecular analysis of introns in Saccharomyces cerevisiae.
TLDR
It is suggested that the current set of 228 yeast introns is still not complete, and that additional intron-containing genes remain to be discovered in yeast, but that splicing in yeast may not be as rigidly determined by splice-site conservation as had previously been thought.
Intron Evolution in Saccharomycetaceae
TLDR
Analysis of a comprehensive set of 250 orthologous introns in the 20 species that comprise the Saccharomycetaceae finds evidence that loss of a small number of introns is mediated by micro-homology, and that the number of intron losses is diminished in yeast species that have lost the microhomology end joining and nonhomologous end joining machinery.
Global Profiling of the Cellular Alternative RNA Splicing Landscape during Virus-Host Interactions
TLDR
This study identifies 240 modified alternative splicing events upon infection which belong to transcripts frequently involved in the regulation of gene expression and RNA metabolism and confirms modifications to transcript-specific peptides resulting from AS in virus- infected cells.
The Transcriptional Landscape of the Yeast Genome Defined by RNA Sequencing
TLDR
A quantitative sequencing-based method is developed for mapping transcribed regions, in which complementary DNA fragments are subjected to high-throughput sequencing and mapped to the genome, and it is demonstrated that most (74.5%) of the nonrepetitive sequence of the yeast genome is transcribed.
Intron gain and loss in the evolution of the conserved eukaryotic recombination machinery.
TLDR
It is postulate that at least one duplication event occurred shortly after the divergence of plants from animals and fungi and that a respective homolog has been retained in a protist group, the apicomplexa.
