Gene Details:

• Gene ID:
• Gene Symbol: IbpreproHypSys
• Gene Name: hydroxyproline-rich preprosystemin
• Genome:
• Species: Ipomoea batatas

Functional Descriptions:

• The expression of IbpreproHypSys, encoding the precursor of IbHypSys, was induced in sweet potato (Ipomoea batatas cv. Tainung 57) through wounding and IbHypSys treatments by using jasmonate and H2O2.
• These results indicated that IbpreproHypSys expression contributed towards sending and receiving the systemic signals that induced IPO expression.
• Analysing the genes involved in the phenylpropanoid pathway demonstrated that lignin biosynthesis was activated after synthetic IbHypSys treatment. IbpreproHypSys expression in sweet potato suppressed Spodoptera litura growth.
• In conclusion, wounding induced the expression of IbpreproHypSys, whose protein product was processed into IbHypSys. IbHypSys stimulated IbpreproHypSys and IPO expression and enhanced lignin biosynthesis, thus protecting plants from insects.
