Chnical replicates of 96 samples grouped in three biological replicates. Asterisks indicate statistically substantial variations (P 0.05)HCT1i:HCT2i-in some of the HCT transgenics and higher in others, however the overall change within the group of plants analyzed was not substantial (P 0.05) (Fig. 5c). Nonetheless, there were important increases within the amounts of sugar released (Fig. 5c) and inside the corresponding calculated GlyT1 Inhibitor Synonyms saccharification efficiencies on the single and double HCT-downregulated plants (Fig. 5d).Regression evaluation of numerous cell wall parameters against saccharification efficiency inside the 15 plants tested showed an inverse correlation among lignin content and saccharification efficiency (Fig. 5e). Only weak optimistic correlations have been noticed among S/G and H/T ratios and saccharification efficiency (R2 = 0.26 and 0.33, respectively) (Fig. 5f,g).HCT1i:HCT2i-HCT1i:HCT2i-HCT1i-CHCT1i-HCT1i-CCSerraniYarce et al.
