SAUR36 Antibody

Functional Roles of SAUR36

SAUR36 is a positive regulator of leaf senescence and mediates auxin-induced developmental processes:

Key Research Findings:

• Leaf Senescence Promotion:

  • SAUR36 knockout mutants exhibit delayed senescence, retaining chlorophyll and photosystem II activity longer than wild-type plants .

  • Overexpression (without 3′ UTR) triggers premature senescence, marked by elevated ion leakage and senescence-associated gene expression .

• Auxin Responsiveness:

  • Contains an auxin response element (TGTCTC) in its 5′ UTR .

  • Transcript levels increase 20-fold within 6 hours of auxin (NAA) treatment .

• Cell Expansion Regulation:

  • saur36 mutants display 67% larger epidermal cells, suggesting SAUR36 inhibits cell expansion .

Research Gaps and Future Directions

• Antibody Validation: No studies directly report SAUR36 antibody use. Cross-reactivity with other SAURs (e.g., SAUR63) must be tested.

• Developmental Stage-Specificity: SAUR36’s 3′ UTR-mediated transcript destabilization suggests antibody utility in distinguishing protein levels during senescence .

• Agricultural Relevance: SAUR36 homologs in crops (e.g., IbSAUR36 in sweet potato) influence root development , highlighting translational potential.
