Gene Details:

• Gene ID: Solyc08g066500
• Gene Symbol: SlHB8
• Gene Name: HD-Zip III family transcription factor 8
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• The SlHB8 acts as a negative regulator in tapetum development and pollen wall formation in Tomato.
• Report the isolation of one HD-Zip III family transcription factor, SlHB8, whose expression levels decreased as pollen development progressed.
• SlHB8 knockout using CRISPR/Cas9 increased pollen activity, subsequently inducing fruit setting, whereas overexpression displayed opposite phenotypes.
• Overexpression lines under control of the 35 s and p2A11 promoters revealed that SlHB8 reduced pollen activity by affecting early pollen development.
• The study findings demonstrate that SlHB8 is involved in tapetum development and degradation and plays an important role in anther development.
