Gene Details:

• Gene ID:
• Gene Symbol: IbEXP1
• Gene Name: expansin gene
• Genome:
• Species: Ipomoea batatas

Functional Descriptions:

• The expressions of IbEXP1, IbEXP2 and IbEXPL1 were significantly correlated with the changes in cell wall component content, and were related to the qualitative structure changes.
• Down-regulation of the IbEXP1 gene enhanced storage root development in sweetpotato.
• The transcript level of IbEXP1 was high in the fibrous root (FR) and petiole at the FR stage, but decreased significantly at the young storage root (YSR) stage.
• Elongation growth of the epidermal cells was significantly reduced, and metaxylem and cambium cell proliferation was markedly enhanced in the FRs of IbEXP1-antisense plants, resulting in an earlier thickening growth in these plants relative to WT plants.
• IbEXP1 is the first sweetpotato gene whose role in SR development has been directly identified in soil-grown transgenic sweetpotato plants.
