Gene Details:

• Gene ID:
• Gene Symbol: StBEL5
• Gene Name: BEL1-related homeotic protein 5
• Genome:
• Species: Solanum tuberosum

Functional Descriptions:

• The level of StBEL5 mRNA increased in response to a short-day photoperiod in both leaves and stolons. Similar to sense mutants of POTH1, transgenic lines that overexpressed StBEL5 exhibited enhanced tuber formation even under noninductive conditions.
• Both StBEL5 and POTH1 sense lines exhibited an increase in cytokinin levels in shoot tips. StBEL5 lines also exhibited a decrease in the levels of GA 20-oxidase1 mRNA in stolon tips from long-day plants.
• Enhanced Tuber Formation in Transgenic Plants That Overexpress the BEL cDNA, StBEL5.
• These results indicate that the enhancement of tuber formation in StBEL5 overexpression lines is not mediated by an indirect increase in POTH1 expression.
• Using a transgenic approach, it is shown that the StPTB family of RNA-binding proteins regulate specific stages of development through an interaction with phloem-mobile transcripts of StBEL5.
