Gene Details:

• Gene ID: Zm00001eb254390
• Gene Symbol: ZmPIN1b pin2
• Gene Name: PIN-formed protein2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmPIN1a and ZmPIN1b modified maize root architecture and plant height.
• An ideal maize phenotype for highly dense cultivation could be produced by ZmPIN1a overexpression.
• For the pyramiding lines of ZmPIN1a antisense and ZmPIN1b antisense lines, weaker transport capabilities and more underdeveloped root systems were observed.
• Constitutive alteration of OsPIN1 expression (a homologous gene of maize ZmPIN1b and ZmPIN1c) changes the tiller number and shoot/root ratio, especially for adventitious root emergence and development.
• ZmPIN1b was highly expressed in leaves (similar to OsPIN1a), whereas ZmPIN1a was primarily expressed in roots at levels lower than that of ZmPIN1b.
