Surface views of roots from susceptible (YZ—a–c) and resistant (BM13H—d–f) G. arboreum seedlings 5 days after inoculation with BRR spores in sterile culture. The roots became colonized in both accessions (black and brown patches, small arrows), but fungal growth is much more advanced on YZ roots, with abundant spores (arrowheads) already formed and more extended root blackening evident. Some BM13H roots support considerable fungal growth (e), but little sporulation. Bars = 0.5 mm.
