A recent study by the Indian Institute of Science (IISc), Bengaluru, has identified self-fertilisation, or uniparental reproduction, as a critical trait enabling plants to become invasive. Researchers examined 28 species from the daisy family, finding that all 11 invasive species studied could reproduce uniparentally, unlike most native and non-invasive alien species. This ability allows a single plant to establish new populations, displacing local flora and altering ecosystems, highlighting the importance of reproductive strategy in weed-risk assessment.
