From: A genome survey of Moniliophthora perniciosa gives new insights into Witches' Broom Disease of cacao
An illustrated hypothetical model for WBD. Model correlating classical symptoms of green and dry broom in the field (A, C and E), M. perniciosa development inside cacao (B: biotrophic stage, D: transition from biotrophic to saprotrophic stage, F: saprotrophic stage) and molecular and cellular events displayed by the fungus in each developmental stages, based on genes annotated in genome survey (right side of the panel). Notice in B (right side) the presence of biotrophic mycelia in the apoplast surrounded by intact living cells. Also notice in C the presence of biotrophic mycelia (arrowhead) and saprotrophic mycelia (double arrowhead) inside a necrotic region. Micrographs scales: B left side: 15 μM; B right side: 25 μM; D: 50 μM; F: 50 μM.
