Gene Details:

• Gene ID: Zm00001eb095020
• Gene Symbol: ZmHMA3a
• Gene Name: heavy metal ATPase3
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmHMA3a is a core valve located at the tonoplast which mediates Cd compartmentalization in the root vacuoles.
• RNA profiling of 24 parental lines of CUBIC revealed that ZmHMA3a was mainly expressed in roots while ZmHMA3b was essentially not expressed in any tissues.
• A heavy metal transporter gene ZmHMA3a promises safe agricultural production on cadmium-polluted arable land.
• ZmHMA3a is the causal locus of natural variation in leaf and kernel Cd of maize.
• ZmHMA3a mediates Cd compartmentalization in the vacuoles of maize roots.
• ZmHMA3a associates with leaf Cd concentration under various Cd levels at seedling and maturing stages.
