Other claims from this paper (10)
- Observation The m30 maize mutant had fewer internodes.
- Observation The m30 maize mutant had shorter internodes.
- Observation The m30 maize mutant had wider internodes.
- Observation Map-based cloning identified ZmCYP90D1 as a candidate gene encoding a cytochrome P450 member.
- Observation ZmCYP90D1 was constitutively expressed, most strongly in basal internodes.
- Observation ZmCYP90D1 protein localized to the nucleus.
- Mechanism A G-to-A substitution was identified as the causal m30 mutation and produced a truncated protein.
- Intervention effect Loss of ZmCYP90D1 function altered hormone-responsive gene expression, especially brassinosteroid-responsive genes.
- Observation Typhasterol concentration was reduced in the ZmCYP90D1 loss-of-function context.
- Mechanism Authors inferred that ZmCYP90D1 influences height and stalk diameter through brassinosteroid-mediated division and growth.
