Fungal growth stops after a narrow interface between the plant's vascular bundles and the fungus has been established. After the micropylar region is reached, hyphae grow further towards the base of the ovary. Within the style, hyphae from different spores join and grow further towards the transmitting tissue. Growth is mainly observed in one direction, i.e. After attachment of spores (asco‐ or conidiospores) to the exposed stigmatic hairs of the ovary style, hyphae penetrate the plant cell wall and the fungus grows within the stigmatic hair cells (yellow line). (B/C) Schematic overview of fungal infection within the rye ovary and the corresponding fluorescence micrograph of a KOH/aniline blue‐stained infected rye ovary. (A) An in vitro method to cultivate isolated rye ovaries on agar plates allows microscopic observation of the early pathogenic development of C. Major aspects of the life cycle of Claviceps purpurea.
