Anaerobic digestion assay of Indica rice straw and rice husk. a Accumulated methane production from day 0 to day 19, in wild-type Minghui 86 (MH86) rice plants, and derived WRI1 transformants. b Maximum methane potential values for MH86, and WRI1 transformants. c Accumulated methane production from day 0 to day 13 (rice straw) and from day 0 to day 25 (rice husk), maximum methane collection values are marked with red circles. d Maximum methane potential values for rice straw and rice husks. Nml: Normal ml (normalized to 1.01325 bar and 273.2 K); TS, Total solids. Mean value ± SD from three biological replicates for MH86, and of five replicates of two lines for WRI1 rice. Indica rice was used to collect rice straw and rice husks for C and D. Asterisks indicate a statistical difference compared to the wild type, significant at *p ≤ 0.05 or **p ≤ 0.01 (Student´s t-test)
