Functional description | Plant species | Gene name | Mutant | Phenotype | Reference |
|---|---|---|---|---|---|
YABBY transcription factor | Arabidopsis thaliana | AtYABBY1, AtFIL, AtAFO | Knockout fil | Altered floral organ number, position, identity, and development during flower development. Partial male sterility. | |
