AtCesA8-driven OsSUS3 expression leads to largely enhanced biomass saccharification and lodging resistance by distinctively altering lignocellulose features in rice

Abstract: BackgroundBiomass recalcitrance and plant lodging are two complex traits that tightly associate with plant cell wall structure and features. Although genetic modification of plant cell walls can potentially reduce recalcitrance for enhancing biomass saccharification, it remains a challenge to maintain a normal growth with enhanced biomass yield and lodging resistance in transgenic plants. Sucrose synthase (SUS) is a key enzyme to regulate carbon partitioning by providing UDP-glucose as substrate for cellulose … Show more

“…Based on the chemical pretreatments with grassy biomass established in our previous works [15][16][17], here we performed various acid and alkali pretreatments with poplar biomass residues (WT) using a series of concentrations of H 2 SO 4 , NaOH, CaO and green liquor (Na 2 S + Na 2 CO 3 ) under different incubation temperatures, and then determined biomass saccharification by calculating hexose yields (% biomass) released from enzymatic hydrolysis of pretreated biomass residues (Additional file 1: Fig. S4).…”

“…Dried and milled poplar was used for analysis of sugar yield. Chemical pretreatment and sequential enzymatic hydrolysis were performed as described previously with minor modifications [16,59]. For H 2 SO 4 pretreatment: the well-mixed biomass samples were treated with 6 mL H 2 SO 4 under various concentrations (0%, 1%, 2%, 4%, 8% v/v) at 120 °C for 20 min, then shaken under 150 rpm at 50 °C for 2 h. For NaOH pretreatment: the well-mixed biomass samples were incubated with 6 mL NaOH under various concentrations (0%, 1%, 2%, 4%, 8% w/v) shaken at 50 °C for 2 h. For CaO pretreatment, the well-mixed biomass samples were treated with CaO at various concentrations (0%, 2%, 5%, 10%, 20% w/w) shaken at 50 °C for 48 h. For Na 2 S + Na 2 CO 3 pretreatment, solution was prepared by mixing Na 2 S and Na 2 CO 3 with a sulfidity (percent ratio of Na 2 S to the sum of Na 2 S and Na 2 CO 3 on Na 2 O basis) of 30%.…”

“…Cellulose crystallinity was not reported, but saccharification was reduced, perhaps due to the increased lignin. A similar approach in transgenic rice (Oryza sativa) lines overexpressing OsSuSy3 under a SCW-specific or a constitutive promoter resulted in dramatic improvements in multiple bioenergy-relevant characteristics (Fan et al, 2017(Fan et al, , 2019. The effects on cell wall composition were similar using either promoter.…”
