Analysis of the yellow-colored compound produced by the ΔkojA_PkojA::wA strain by UPLC-MS. The chromatograms of the yellow-colored compound denoted as A. oryzae sample and the YWA1 standard by UPLC (a) and MS (b) are shown. The UPLC chromatograms are taken at 280 nm, while the MS chromatograms are taken at m/z: 277. X-axes; retention time (min): Y-axes; absorbance at 280 nm (a) and signal intensity (b)
