Inter-Species Gene Transfer Enabled by Selfish DNA

Researchers have discovered that certain roundworms carry a genetic element known as a Maverick, which is capable of transferring genes between species. Mavericks are massive mobile genetic elements that were previously thought to be inactive relics, but this study reveals their ability to mediate horizontal gene transfer. The Maverick in the roundworms contains viral genes and a fusogen protein, suggesting its ability to form virus-like particles and invade different cell types. Further research is needed to observe the Maverick in action and understand its mechanisms. This discovery could have practical applications in controlling parasites that infect agricultural crops and livestock. Additionally, similar massive transposons called Starships have been found in fungi, potentially playing a role in the spread of wheat diseases. Understanding these genetic transfer mechanisms is crucial for comprehending genome evolution.
