TLDR
Patterns of intron-position correspondence between widely diverged eukaryotic species have provided insights into the origins of the vast differences in intron number between eukARYotic species, and studies of specific cases of introns loss and gain have led to progress in understanding the underlying molecular mechanisms and the forces that control intron evolution.Abstract:
The origins and importance of spliceosomal introns comprise one of the longest-abiding mysteries of molecular evolution. Considerable debate remains over several aspects of the evolution of spliceosomal introns, including the timing of intron origin and proliferation, the mechanisms by which introns are lost and gained, and the forces that have shaped intron evolution. Recent important progress has been made in each of these areas. Patterns of intron-position correspondence between widely diverged eukaryotic species have provided insights into the origins of the vast differences in intron number between eukaryotic species, and studies of specific cases of intron loss and gain have led to progress in understanding the underlying molecular mechanisms and the forces that control intron evolution.read more

TL;DR: The discovery of the secreted protein gene clusters and the functional demonstration of their decisive role in the infection process illuminate previously unknown mechanisms of pathogenicity operating in biotrophic fungi.

Quality control of eukaryotic mRNA: safeguarding cells from abnormal mRNA function
Olaf Isken,Lynne E. Maquat +1 more
TL;DR: An overview of three quality control mechanisms--nonsense-mediated RNA decay, nonstop mRNA decay, and no-go mRNA decay--is provided, which surveys mRNAs during translation and degrades those m RNAs that direct aberrant protein synthesis.

Comparative Aspects of Animal Regeneration
Jeremy P. Brockes,Anoop Kumar +1 more
TL;DR: The evolutionary origins of regeneration and how regeneration may relate to both agametic reproduction and to ontogeny are considered, including examples of species that are able to regenerate large sections of the body plan.

RNA-based gene duplication: mechanistic and evolutionary insights.
TL;DR: A range of recent studies that have unveiled a significant number of functional retroposed gene copies in both mammalian and some non-mammalian genomes have provided fascinating general insights into molecular and evolutionary processes that have shaped genomes.
Journal ArticleDOI
Rapidly regulated genes are intron poor
TL;DR: It is proposed that introns can delay regulatory responses and are selected against in genes whose transcripts require rapid adjustment for survival of environmental challenges.

The Selfish Gene
TL;DR: In this paper, the authors take up the concepts of altruistic and selfish behaviour; the genetical definition of selfish interest; the evolution of aggressive behaviour; kinship theory; sex ratio theory; reciprocal altruism; deceit; and the natural selection of sex differences.

Selfish DNA: the ultimate parasite
Leslie E. Orgel,Francis Crick +1 more
TL;DR: The DNA of higher organisms usually falls into two classes, one specific and the other comparatively nonspecific, and it seems plausible that most of the latter originated by the spreading of sequences which had little or no effect on the phenotype.

Gene Regulation for Higher Cells: A Theory
Roy J. Britten,Eric H. Davidson +1 more
TL;DR: Direct support for the idea that regulation of gene activity underlies cell differentiation comes from evidence that much of the genome in higher cell types is inactive and that different ribonucleic acids are synthesized in different cell types.
