Gene Details

Functions:

  • WI5 functions in xylem cell wall thickening through its xylanase activity and thereby regulates xylem water transport, the drought stress response, and plant growth in maize.
  • Maize WI5 encodes an endo-1,4-β-xylanase required for secondary cell wall synthesis and water transport in xylem.
  • WI5 functions in the formation of the secondary cell wall and plays an essential role in increasing the thickness of the internode xylem required for efficient water transport, thereby helping plants develop normally under high transpiration and water-stress conditions.
