Gene Details:

• Gene ID: Zm00001eb179190
• Gene Symbol: ZmBADH2a aldh11
• Gene Name: aldehyde dehydrogenase11
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• These results suggest that ZmBADH2a and ZmBADH2b redundantly participate in 2AP biosynthesis in maize, and represent the creation of the world’s first aromatic maize by simultaneous genome editing of the two BADH2 genes.
• Here, we characterized the two maize BADH2 homologs, ZmBADH2a and ZmBADH2b. We generated ZmBADH2a and zmbadh2b single mutants and the ZmBADH2a-zmbadh2b double mutant by CRISPR/Cas in four inbred lines. A popcorn-like scent was only noticeable in seeds from the double mutant, but not from either single mutant or in wild type.
• These results demonstrated that ZmBADH2a and ZmBADH2b are both involved in 2AP biosynthesis and only their combined inactivation results in 2AP accumulation in maize.
