Gene Details:

• Gene ID: Solyc02g085910
• Gene Symbol: SlLBD40
• Gene Name: LOB DOMAIN-CONTAINING PROTEIN 40
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• Overexpression of SlLBD40 significantly promoted fruit growth by promoting mesocarp cell expansion, while knockout of SlLBD40 showed the opposite result.
• The co-expression of SlMYC2 and SlLBD40 significantly stimulated the activation of SlEXPA5, leading to an increase in fruit size.
• These results indicated that fruit size was significantly enhanced in SlLBD40-OE plants and suppressed in SlLBD40-KO mutant plants.
• SlLBD40 regulates fruit size by controlling cell size.
• CRISPR/Cas9 targeted mutagenesis of SlLBD40, a lateral organ boundaries domain transcription factor, enhances drought tolerance in tomato.
