General Information

General Information	Comment	Organism
malfunction	the lignin of the fnsII mutant is completely devoid of tricin, indicating that FNSII activity is essential for the deposition of tricin-bound lignin in rice cell walls. The mutant also shows substantially reduced lignin content with decreased syringyl/guaiacyl lignin unit composition. The loss of tricin in the mutant lignin appears to be partially compensated by incorporating naringenin, which is a preferred substrate of OsFNSII. The fnsII mutant is further revealed to have enhanced enzymatic saccharification efficiency, suggesting that the cell wall recalcitrance of grass biomass may be reduced through the manipulation of the flavonoid monomer supply for lignification	Oryza sativa
metabolism	the enzyme plays an essential role in tricin lignification in the cell wall	Oryza sativa
