Germicide Fenaminosulf Promots Gall Formation of Zizania latifolia without directly affecting the growth of endophytic fungus Ustilago esculenta.

ABSTRACT: Zizania latifolia is a popular aquatic vegetable in China because of its enlarged edible stems resulting from persistent infection by a fungal endophyte, Ustilago esculenta. Fenaminosulf (FM) is a germicide that can be used to improve agricultural crop yields. In Z. latifolia fields, appropriate spraying of FM not just controls diseases, but also promotes an earlier harvest of Z. latifolia. In this study, we show that the timing of gall formation was advanced and the plant's yield was increased significantly under a high concentration treatment of FM. Yet FM had a strong inhibitory effect on the growth of U. esculenta in vitro, while the transcript levels of mating-type alleles, cell metabolism-related genes and chitin synthase genes were all substantially downregulated. Through a transcri
