Effect of Amiprophosmethyl on Mitotic Index and Micronucletion in Helianthus annuus Protoplasts

Key Points

• Mitotic index decreased in Helianthus annuus protoplasts treated with amiprophosmethyl, indicating a possible growth effect.
• Micronucleation frequency increased under treatment, suggesting potential genomic instability in plant cells.
• Assessment using protoplasts from sunflower (Helianthus annuus) reveals the direct impact of amiprophosmethyl on cell division processes.
• Findings may highlight the importance of examining chemical effects on plant cell biology and reveal risks for agricultural use.
