Gene Details:

• Gene ID: Zm00001eb217500
• Gene Symbol: WI5 Zmxyl
• Gene Name: wilted5
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The maize (Zea mays) wilty5 (WI5) mutant, which exhibits marked dwarfing and leaf wilting throughout most of its life cycle under normal growth conditions.
• WI5 mutant plants displayed a drought-sensitive phenotype, with wilting and progressive leaf chlorosis after the 3-leaf stage.
• Map-based cloning revealed that WI5 encodes an active endo-1,4-β-xylanase from glycosyl dehydration family 10, which mainly functions in degrading and reorganizing cell wall xylan.
• 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.
