Time-lapse imaging analysis of A. oryzae penetration into steamed rice. The sections of koji Y50 (a, b) and Y90 (c, d), A. oryzae (green), rice cells (red), were imaged every 10 or 20 min for 14 h by fluorescent microscopy. See also Additional files 4, 5: Movies S3 and S4. Time-lapse images (a, b) and broader images at 14 h (b, d). a Some hyphae changed the growth direction after hitting the rice cell shape (arrows).
