Photocontrol of Fungal Spore Germination

- Summary
- Metrics

Abstract

Germination of Puccinia graminis f. sp. tritici uredospores is inhibited by continuous irradiation. Prehydration of spores enhances both dark germination and photoinhibition. Simultaneous irradiation with ineffective red (653 nanometers) and inhibitory far red light (720 nanometers) results in partial nullification of the inhibition brought about by far red light alone. This result would be consistent with the involveent of a photoreversible pigment system similar to phytochrome, operating via the high irradiance reaction.
