Unlabelled: In this study, we identified 19 intron losses, including 11 precise intron losses (PILs), six imprecise intron losses (IILs), one de-exonization, and one exon deletion in tomato and potato, and 17 IILs in Arabidopsis thaliana. Comparative analysis of related genomes confirmed that all of the IILs have been fixed during evolution. Consistent with previous studies, our results indicate that PILs are a major type of intron loss. However, at least in plants, IILs are unlikely to be as rare as previously reported.

The massive increase in the amount of plastid genome data have allowed researchers to address a variety of evolutionary questions within a wide range of plant groups. While plastome structure is generally conserved, some angiosperm lineages exhibit structural changes. Such is the case of the megadiverse order Asterales, where rearrangements in plastome structure have been documented.

Background: Primary transcripts are largely comprised of intronic sequences that are excised and discarded shortly after synthesis. In vertebrates, the shape of the intron size distribution is largely constant; however, most teleost fish have a diverged log-bimodal 'teleost distribution' (TD) that is seen only in teleosts. How the TD evolved and to what extent this was affected by adaptative or non-adaptive mechanisms is unknown.

Shrimp aquaculture is facing a serious disease, acute hepatopancreatic necrosis disease (AHPND), caused by (Vp). For sustainable shrimp aquaculture, massive losses of shrimp infected with Vp must be prevented. Research and selection of shrimp tolerant to Vp infection is a sustainable approach to reducing the risk of AHPND.

Article Synopsis
- Differences of sex development (DSD) in pigs, particularly XX DSD pigs, lead to atypical reproductive organ formation and significant economic losses in farming due to their underdeveloped gonads.
- * Anatomical analyses and whole-genome sequencing identified specific genetic mutations associated with XX DSD pigs, including notable SNPs in genes like IFITM1 and NOBOX.
- * The study's findings suggest that understanding these genetic changes can help explain the underlying causes of DSD in pigs and potentially aid in developing better breeding strategies.
