Gene Details:

• Gene ID: Zm00001eb203950
• Gene Symbol: ZmVPS29 vps29
• Gene Name: vacuolar protein sorting29
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmVPS29 increased auxin accumulation during early kernel development by enhancing auxin biosynthesis and transport and reducing auxin degradation and thereby improved kernel development.
• Overexpression of ZmVPS29 conferred a slender kernel morphology and increased the yield per plant in different maize genetic backgrounds.
• ZmVPS29 might play a role in the maintenance of auxin homeostasis in vivo by regulating auxin accumulation in maize kernel development through a combination of auxin biosynthesis, transport and degradation.
• Positional cloning and transgenic analysis revealed that qKM4.08 encodes ZmVPS29, a retromer complex component.
• Further study showed that ZmVPS29 increased auxin accumulation during early kernel development by enhancing auxin biosynthesis and transport and reducing auxin degradation and thereby improved kernel development.
• Sequence analyses suggest that ZmVPS29 has been under purifying selection during maize domestication and likely in breeding processes as well.
