Diverse pathways to speciation revealed by marine snails
Trends Genet. 2024 Feb 22:S0168-9525(24)00002-7. doi: 10.1016/j.tig.2024.01.002. Online ahead of print.ABSTRACTSpeciation is a key evolutionary process that is not yet fully understood. Combining population genomic and ecological data from multiple diverging pairs of marine snails (Littorina) supports the search for speciation mechanisms. Placing pairs on a one-dimensional speciation continuum, from undifferentiated populations to species, obscured the complexity of speciation. Adding multiple axes helped to describe either speciation routes or reproductive isolation in the snails. Divergent ecological selection repeatedly...

Genetic adaptations for the oceanic success of fish eggs
Trends Genet. 2024 Feb 22:S0168-9525(24)00004-0. doi: 10.1016/j.tig.2024.01.004. Online ahead of print.ABSTRACTGenetic adaptations of organisms living in extreme environments are fundamental to our understanding of where life can evolve. Water is the single limiting parameter in this regard, yet when released in the oceans, the single-celled eggs of marine bony fishes (teleosts) have no means of acquiring it. They are strongly hyposmotic to seawater and lack osmoregulatory systems. Paradoxically, modern teleosts successfully release vast quantities of eggs in the extreme saline environment and recorded the most explosive r...

Directing RNA-modifying machineries towards endogenous RNAs: opportunities and challenges
Trends Genet. 2024 Feb 12:S0168-9525(24)00001-5. doi: 10.1016/j.tig.2024.01.001. Online ahead of print.ABSTRACTOver 170 chemical modifications can be naturally installed on RNA, all of which are catalyzed by dedicated machineries. These modifications can alter RNA sequence structure, stability, and translation as well as serving as quality control marks that record aspects of RNA processing. The diverse roles played by RNAs within cells has motivated endeavors to exogenously introduce RNA modifications at target sites for diverse purposes ranging from recording RNA:protein interactions to therapeutic applications.

Clocks at sea: the genome-editing tide is rising
Trends Genet. 2024 Feb 8:S0168-9525(24)00006-4. doi: 10.1016/j.tig.2024.01.006. Online ahead of print.ABSTRACTThe coastline is a particularly challenging environment for its inhabitants. Not only do they have to cope with the solar day and the passing of seasons, but they must also deal with tides. In addition, many marine species track the phase of the moon, especially to coordinate reproduction. Marine animals show remarkable behavioral and physiological adaptability, using biological clocks to anticipate specific environmental cycles. Presently, we lack a basic understanding of the molecular mechanisms underlying circat...

Finding genes and pathways that underlie coral adaptation
Trends Genet. 2024 Feb 5:S0168-9525(24)00003-9. doi: 10.1016/j.tig.2024.01.003. Online ahead of print.ABSTRACTMass coral bleaching is one of the clearest threats of climate change to the persistence of marine biodiversity. Despite the negative impacts of bleaching on coral health and survival, some corals may be able to rapidly adapt to warming ocean temperatures. Thus, a significant focus in coral research is identifying the genes and pathways underlying coral heat adaptation. Here, we review state-of-the-art methods that may enable the discovery of heat-adaptive loci in corals and identify four main knowledge gaps. To fi...

Online ahead of print.ABSTRACTPlant biotechnology plays a crucial role in developing modern agriculture and plant science research. However, the delivery of exogenous genetic material into plants has been a long-standing obstacle. Nanoparticle-based delivery systems are being established to address this limitation and are proving to be a feasible, versatile, and efficient approach to facilitate the internalization of functional RNA and DNA by plants. The nanoparticle-based delivery systems can also be designed for subcellular delivery and contr...

An ocean of diffusible information
Trends Genet. 2024 Feb 2:S0168-9525(24)00007-6. doi: 10.1016/j.tig.2024.01.007. Online ahead of print.ABSTRACTIn the ocean, free-living bacteria exist in a dilute world where direct physical interactions between cells are relatively rare. How then do they exchange genetic information via horizontal gene transfer (HGT)? Lücking et al. have explored the world of marine 'protected extracellular DNA' (peDNA), and find that extracellular vesicles (EVs) are likely to play an important role.PMID:38310066 | DOI:10.1016/j.tig.2024.01.007 (Source: Trends in Genetics : TIG)
