Publication Type: Peer Reviewed Journal Publication Acceptance Date: 10/1/2014 Publication Date: 11/7/2014 Citation: Zhan, G.M., Tian, Y., Wang, F.P., Chen, X., Guo, J., Jiao, M., Huang, L.L., Kang, Z.S. 2014. A novel fungal hyperparasite of Puccinia striiformis f. sp. tritici, the causal agent of wheat stripe rust. PLoS One. 9(11):e111484. Interpretive Summary: The causal fungus of wheat stripe rust was previously reported to be infected by three fungi: Lecanicillium lecanii, Microdochium nivale and Typhula idahoensis. Here, we report a novel hyperparasite of the stripe rust fungus. This hyperparasitic fungus was identified as Cladosporium cladosporioides based on morphological characteristics observed by light and scanning electron microscopy together with molecular data. The hyperparasite reduced the production and viability of urediniospores and, therefore, could potentially be used for biological control of wheat stripe rust. Technical Abstract: Puccinia striiformis f. sp. tritici (Pst), the causal fungus of wheat stripe rust, was previously reported to be infected by Lecanicillium lecanii, Microdochium nivale and Typhula idahoensis. Here, we report a novel hyperparasite on Pst. This hyperparasitic fungus was identified as Cladosporium cladosporioides (Fresen.) GA de Vries based on morphological characteristics observed by light and scanning electron microscopy together with molecular data. The hyperparasite reduced the production and viability of urediniospores and, therefore, could potentially be used for biological control of wheat stripe rust. |
