Gene Details:
- Gene ID:
- Gene Symbol: GhKNL1
- Gene Name: class II KNOX protein 1
- Genome: TM1_NBI
- Species: Gossypium hirsutum
Functional Descriptions:
- Overexpression of GhKNL1 reduces the expression of GhXTH1, Gh1,3-β-G, the cell wall protein GhAGP4, and SCW biosynthesis genes such as GhCesA4, thus resulting in decreased fiber length and thinner SCWs.
- GhHUB2 ubiquitinates GhKNL1 and directs its degradation through the ubiquitin–26S proteasome-dependent pathway. Our study thus reveals a novel function of HUB2 in plants.
- GhKNL1, which is predominantly expressed in developing fibers.
- hHUB2 negatively regulated GhKNL1 protein levels and lead to the disinhibition of genes such as GhXTH1, Gh1,3-β-G, GhCesA4, GhAGP4, GhCTL1, and GhCOBL4, thus promoting fiber elongation and enhancing SCW biosynthesis.
