Cytochrome P450 93G1 Is a Flavone Synthase II That Channels Flavanones to the Biosynthesis of Tricin O-Linked Conjugates in Rice1[C][W]
TLDR
It is established that CYP93G1 is a key branch point enzyme channeling flavanones to the biosynthesis of tricin O-linked conjugates in rice and functional diversification of F2H and FNSII in the cytochrome P450 CYP 93G subfamily may represent a lineage-specific event leading to the prevalent cooccurrence of flavone C- and O- linked derivatives in grasses today.

Completion of Tricin Biosynthesis Pathway in Rice: Cytochrome P450 75B4 Is a Unique Chrysoeriol 5′-Hydroxylase1
TLDR
It is reported here that CYP75B4 a unique flavonoid B-ring hydroxylase indispensable for tricin formation in rice and recruitment of chrysoeriol-specific 5′-hydroxyl enzyme activity by an ancestral CYP 75B sequence may represent a key event leading to the prevalence oftricin-derived metabolites in grasses and other monocots today.

Sorghum extracellular leucine-rich repeat protein SbLRR2 mediates lead tolerance in transgenic Arabidopsis.
TLDR
Investigations revealed the Pb(II)-induced transcriptional activation of SbLRR2 and several highly conserved AtPDR12 homologs in sorghum seedlings, suggesting the possibility of a common molecular mechanism for P b(II) tolerance in diverse plant species. Expand
Fibre‐specific regulation of lignin biosynthesis improves biomass quality in Populus
TLDR
It is demonstrated that fibre‐specific suppression of lignin biosynthesis resulted in the improvement of wood biomass quality and saccharification efficiency and presents an effective strategy to precisely regulate lign in biosynthesis with desired growth performance. Expand
The Arabidopsis R2R3 MYB Transcription Factor MYB15 Is a Key Regulator of Lignin Biosynthesis in Effector-Triggered Immunity
TLDR
It is demonstrated that regulation at the transcriptional level is key to pathogen-induced lignification and that MYB15 plays a central role in this process. Expand
Disrupting Flavone Synthase II Alters Lignin and Improves Biomass Digestibility1[OPEN]
TLDR
The tricin-deficient fnsII mutant was analyzed further and 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. Expand
OsCAldOMT1 is a bifunctional O-methyltransferase involved in the biosynthesis of tricin-lignins in rice cell walls
TLDR
Cell wall structural analyses establish OsCAldOMT1 as a bifunctional O-methyltransferase predominantly involved in the two parallel metabolic pathways both dedicated to the biosynthesis of tricin-lignins in rice cell walls. Expand
Recruitment of specific flavonoid B-ring hydroxylases for two independent biosynthesis pathways of flavone-derived metabolites in grasses.
In rice (Oryza sativa), OsF2H and OsFNSII direct flavanones to independent pathways that form soluble flavone C-glycosides and tricin-type metabolites (both soluble and lignin-bound), respectively.Expand
Convergent recruitment of 5´-hydroxylase activities by CYP75B flavonoid B-ring hydroxylases for tricin biosynthesis in Medicago legumes.
TLDR
Investigation of a subgroup of cytochrome P450 (CYP) 75B subfamily flavonoid B-ring hydroxylases (FBHs) from two tricin-accumulating legumes revealed that these Medicago legumes had acquired thetricin pathway through molecular evolution of CYP75B FBHs subsequent to speciation from other non-tricin-coating legumes.

Termite Gut Microbiota Contribution to Wheat Straw Delignification in Anaerobic Bioreactors
Lignin is a major lock for lignocellulose valorization in biorefineries, prompting a need to find new ligninolytic systems. Termites are efficient lignocellulose degraders, and a large part of this...
