Gene expression plays a crucial role in how organisms adapt to environmental changes, but the impact of gene organization on this process during invasions is still under-researched.
A study using the invasive species Ciona robusta revealed that neighboring genes tend to be co-expressed and a significant percentage of stress-responsive genes are physically clustered, with their expression influenced by their spatial arrangement.
High salinity challenges were shown to disrupt this coordinated expression, indicating that gene clustering and organization affect adaptability during environmental stress.
