Gene Details:

• Gene ID: Zm00001eb133200
• Gene Symbol: Zmksl4 ZmKS3 ZmKSL2 ZmTPS11 ks4
• Gene Name: kaurene synthase4
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Generation and analysis of CRISPR-Cas9-derived loss-of-function Kaurene Synthase-Like 4 (Zmksl4) mutants demonstrated dolabralexin production deficiency, thus supporting Zmksl4 as the diterpene synthase responsible for the conversion of geranylgeranyl pyrophosphate precursors into dolabradiene and downstream pathway products.
• Zmksl4 mutants further display altered root-to-shoot ratios and root architecture in response to water deficit.
• these results demonstrate dolabralexin biosynthesis via Zmksl4 as a committed pathway node biochemically separating kauralexin and dolabralexin metabolism, and suggest an interactive role of maize dolabralexins in plant vigor during abiotic stress.
