Gene Details:

• Gene ID: NbS00007680g0013.1
• Gene Symbol: NbEXPA1
• Gene Name: α-expansin protein
• Genome:
• Species: Nicotiana benthamiana

Functional Descriptions:

• NbEXPA1, an α-expansin, is plasmodesmata-specific and a novel host factor for potyviral infection.
• Among the differentially accumulated PD protein candidates, we show that an α-expansin designated NbEXPA1, a cell wall loosening protein, is PD-specific.
• Silencing of NbEXPA1 inhibits plant growth and TuMV infection, whereas overexpression of NbEXPA1 promotes viral replication and intercellular movement.
• These data suggest that NbEXPA1 is a host factor for potyviral infection. This study not only generates a PD-proteome dataset that is useful in future studies to expound PD biology and PD-mediated virus–host interactions but also characterizes NbEXPA1 as the first PD-specific cell wall loosening protein and its essential role in potyviral infection.
