Gene Details:

• Gene ID: Zm00001eb048020
• Gene Symbol: AN1
• Gene Name: anther ear1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The Anther ear1 (AN1) gene product is involved in the synthesis of ent-kaurene, the first tetracyclic intermediate in the gibberellin (GA) biosynthetic pathway.
• Mutations causing the loss of AN1 function result in a GA-responsive phenotype that includes reduced plant height, delayed maturity, and development of perfect flowers on normally pistillate ears.
• The semidwarfed stature of AN1 mutants is in contrast with the more severely dwarfed stature of GA-responsive mutants at other loci in maize and may be caused by redundancy in this step of the GA biosynthetic pathway.
• AN1 increase in number of brace root whorls.
• DNA gel blot analysis indicated that AN1 is a single-copy gene that lies entirely within the deletion of the AN1-bz2-6923 mutant.
