Gene Details:

• Gene ID:
• Gene Symbol: StbHLH93
• Gene Name: transcription factor bHLH93-like
• Genome:
• Species: Solanum tuberosum

Functional Descriptions:

• We identified a novel tuber-specific basic helix–loop–helix (bHLH) transcription factor, StbHLH93, based on the high-resolution transcriptome of potato tuber development.
• StbHLH93 is predominantly expressed in the subapical and perimedullary region of the stolon and developing tubers.
• Knockdown of StbHLH93 significantly decreased tuber number and size, resulting from suppression of stolon swelling.
• StbHLH93 directly binds to the plastid protein import system gene TIC56 promoter, activates its expression, and is involved in proplastid-to-amyloplast development during the stolon-to-tuber transition.
• StbHLH93 functions in the differentiation of proplastids to regulate stolon swelling.
