Key Findings
- The study by Hainan University identified 12 AcHMA genes in the genome of Areca catechu (betel nut palm)
- These genes are unevenly distributed across six chromosomes and show varied expressions in different tissues
- AcHMA1 and AcHMA3 are significantly up-regulated in response to cadmium (Cd2+) and zinc (Zn2+) stress, suggesting their role in mitigating heavy metal effects
