Gene Details:

  • Gene ID:
  • Gene Symbol: PtrMAN6
  • Gene Name: Populus endo-1,4-β-mannanase
  • Genome:
  • Species: Populus trichocarpa

Functional Descriptions:

  • Populus endo-beta-mannanase PtrMAN6 plays a role in coordinating cell wall remodeling with suppression of secondary wall thickening through generation of oligosaccharide signals.
  • PtrMAN6 is expressed specifically in xylem tissue and its encoded protein localizes to developing vessel cells.
  • Overexpression of PtrMAN6 enhanced wall loosening as well as suppressed secondary wall thickening, whilst knockdown of its expression promoted secondary wall thickening.
  • Application of the oligosaccharides resulted in cellular and transcriptional changes that were similar to those found in PtrMAN6 overexpressed transgenic plants.
  • Overall, our results demonstrated that PtrMAN6 plays a role in hydrolysis of mannan-type wall polysaccharides to produce oligosaccharides that may serve as signaling molecules to suppress cell wall thickening during wood xylem cell differentiation.
