- AHL14 and AHL29 are Arabidopsis transcription factors that repress seed oil accumulation.
- They inhibit oil deposition by directly suppressing PDH-E1 β1 and BCCP2, key fatty acid biosynthesis genes.
- AHL14 and AHL29 physically interact and cooperatively repress oil accumulation.
- KIN10 phosphorylates AHL14, leading to its proteasomal degradation, which alleviates repression of oil accumulation.
- AHL14 and AHL29 indirectly suppress WRI1 expression, another regulator of oil production negatively regulated by KIN10.
- The study reveals a KIN10-AHL14-AHL29 module that fine-tunes oil production in seeds, complementing the KIN10-WRI1 pathway.
