Splicing: Unmasking exitrons
Eytan Zlotorynski.
Kalyna and colleagues characterized protein-coding exonic sequences that can undergo alternative splicing, which they termed exonic introns (exitrons; previously termed cryptic introns). They defined >1,000 exitrons in >3% of Arabidopsis thaliana coding genes, including in many genes annotated as intron-less, and found that they
