Gene Details:
- Gene ID:
- Gene Symbol: SlEIN4
- Gene Name: ETHYLENE INSENSITIVE4
- Genome: Tomato Genome version SL4.0
- Species: Solanum lycopersicum
Functional Descriptions:
- Our study pinpointed an ethylene receptor gene, SlEIN4, located on chromosome 4 through a genome-wide association study (GWAS) of fruit firmness in the 266 tomato core accessions.
- A single-nucleotide polymorphism (SNP) (A→G) of SlEIN4 distinguished lower (AA) and higher (GG) fruit firmness genotypes.
- Observed that overexpression of SlEIN4AA significantly delayed tomato fruit ripening and dramatically reduced fruit firmness at the red ripe stage compared with the control.
- SlEIN4 exerts a negative regulatory role in tomato ripening by impacting ethylene evolution through the abundant expression of ethylene pathway regulatory genes.
- SlEIN4 negatively regulates tomato fruit ripening by affecting ethylene downstream signalling.
