Summary

[edit]
Description
Français : Cycle de vie du champignon phytoparasite Microbotryum violaceum Une plante en bonne santé est infectée par des téliospores de M. violaceum (1) . Les téliospores germent, subissent une méiose et produisent des sporidies semblables à des levures (2). La conjugaison a lieu sur la plante entre sporidies de types sexuels opposés (3). Les hyphes dicaryotes poussent dans la plante (4) et passent l'hiver dans les tissus végétatifs (5). L'année suivante, l'infection est systémique (6) et toutes les fleurs produisent des téliospores diploïdes dans les anthères (7) et sont transmises par des pollinisateurs (8) sur une autre plante saine (1).
